New current meter at Stevens will feed data into NOAA’s real-time information system to allow ships to navigate more safely in New York harbor

April 29, 2013

NOAA is using data from a new current meter in New York harbor, operated by one of its academic partners, New Jersey’s Stevens Institute of Technology, to provide enhanced real-time information to mariners travelling through the nation’s second busiest port.

The Stevens current meter measures the  direction, speed, and volume of ocean currents in the harbor’s navigation channels, north of the Narrows between Brooklyn and Staten Island.  Its data will be used in NOAA’s Physical Oceanographic Real-Time System (PORTS®) system, which delivers real-time environmental observations, forecasts and other geospatial information to mariners in 21 major U.S. harbors. The system makes maritime commerce more safe and efficient by giving ship captains instant measurements of the water levels and temperatures, and the direction and speed of the current and wind as they come in and out of port.

Stevens is a partner in the NOAA-led U.S. Integrated Ocean Observing System (IOOS®) , and is the first academic institution that is part of IOOS to have its research data incorporated into the NOAA real-time PORTS program.

"This new sensor will provide crucial current information halfway between the Verrazano Narrows Bridge and Manhattan, the primary navigation route into New York and New Jersey ports. It’s a great addition to PORTS,” said Richard Edwing, director of NOAA’s Center for Operational Oceanographic Products and Services. “This collaboration between Stevens and NOAA gives us access to previously untapped data to help us address marine commerce and other coastal issues.  It also lays the groundwork for future federal-regional collaborations.”

By providing real-time tide, current, and other information, NOAA’s PORTS program helps reduce the chances for accidents. Also, enhanced marine information can increase the amount of cargo moved through a port and harbor by enabling mariners to safely use every inch of dredged channel depth.

“This is how the national IOOS network – with federal, regional, academic, and private sector partnerships – is bringing more data and information to the table from more sources than the government has had access to before,” said Zdenka Willis, U.S. IOOS program director. “In these tough economic times, IOOS is really helping us do more for our nation at lower cost.”

IOOS brings together timely, reliable, and accurate data and information decision makers need to take action to improve safety, enhance the economy and protect the environment. These data provide a larger picture of the interaction between the ocean and global climate systems and advance our understanding of potential climate change impacts on our marine ecosystems and coastal communities.

NOAA’s Office of Response and Restoration has launched a new online mapping tool for the Great Lakes that will give decision makers, resource managers, and environmental responders better information as they clean up hazardous materials and restore the coastal and estuarine environments.

The new Great Lakes Environmental Response Management Application (ERMA®) tool features the most comprehensive collection of environmental contaminant data in the region, as well as information on natural resources, habitats, weather, water levels, and currents.

Great Lakes ERMA adds to ERMA coverage in other regions around the nation, and focuses on coastal areas in the Great Lakes Basin from Minnesota to New York and from Ontario to Quebec in Canada. It integrates both static and real-time data from NOAA and other partners into a centralized, easy-to-use format.

By combining environmental contaminant data from NOAA’s Great Lakes Query Manager database with ecological, recreational, cultural, and commercial information, resource managers can compare environmental conditions over time and between locations.

ERMA helps to illustrate progress in cleaning up contaminated sediment and restoring the health of the Great Lakes, both across the basin and in Areas of Concern -- areas identified by the U.S. and Canada as polluted and in need of cleanup and restoration.

As part of the Great Lakes Restoration Initiative, NOAA developed Great Lakes ERMA,  in collaboration with EPA, U.S. Coast Guard, and University of New Hampshire.

In addition to addressing environmental cleanup and restoration under the initiative, Great Lakes ERMA also improves planning, communication, and coordination for emergency responses to pollution incidents, such as oil and chemical spills. It integrates information from a variety of sources into a common picture, which can provide the response team with a quick visualization of the situation.

NOAA continues to work with federal, state, regional and non-governmental partners in the Great Lakes to incorporate additional, regionally relevant data and information into Great Lakes ERMA, including restoration projects and alternatives, potential climate change impacts, spill response plans, and environmental modeling and forecasts.

Sanctuaries establishes new business advisory council

September 12, 2013

NOAA’s Office of National Marine Sanctuaries has established a new business advisory council to give its director the views of industry leaders as they work with corporate partners in marine resource protection.

“The ocean is a fundamental part of the U.S. economy, security, history, and culture,” said Daniel J. Basta, director of the Office of National Marine Sanctuaries.“However, the relationship between the conservation and commercial sectors is not well understood or coordinated. We hope this council will help us bridge that divide.”

Business leaders will be invited to join the council, which will consist of 15 volunteers representing industries such as travel and tourism, recreation, fishing, transportation, energy, and marketing. Members will be appointed by the national marine sanctuaries director and serve two- to three-year terms.

Council members will serve as liaisons between their industries and NOAA, keeping sanctuary leadership informed of issues and concerns, as well as providing information to their respective sectors about national marine sanctuary system initiatives. The council will not have a role in providing advice on regulatory or administrative matters.

The council will work with sanctuary leadership on strategies to use the sanctuary system’s recreational value and beauty to aid local economies, engage the corporate sector and other non-traditional partners in marine resource protection, and develop projects to sustain and protect the sanctuaries and other marine protected areas, among other initiatives.

For additional information about the business council, visit http://sanctuaries.noaa.gov/management/bac/

NOAA’s Office of National Marine Sanctuaries serves as trustee for a system of 14 marine protected areas, encompassing more than 170,000 square miles of America’s ocean and Great Lakes waters. Through active research, management, and public engagement, national marine sanctuaries sustain healthy environments that are the foundation for thriving communities and stable economies. Authority for the business advisory council is provided under the National Marine Sanctuaries Act.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter, Instagram and our other social media channels.

Partners deploy underwater robots to improve hurricane science

September 9, 2013

A fleet of underwater robots is descending into waters off the east coast to collect data that could help improve storm intensity forecasts during future hurricane seasons. Several regions of the NOAA-led U.S. Integrated Ocean Observing System (IOOS®) are partnering to deploy 12 to 16 autonomous underwater robotic vehicles, also known as gliders, from Nova Scotia to Georgia.  

The gliders will be available through the peak fall Atlantic storm season to collect data on ocean conditions, which will help improve scientists’ understanding of hurricanes and pave the way for future improvements in hurricane intensity forecasts.  

“When storms are moving along our coasts, lives depend on accurate forecasts,” said Zdenka Willis, U.S. IOOS program director. “The unmanned gliders will allow us to collect data even in the middle of the storm and eventually provide this information to NOAA’s National Weather Service to help improve forecast precision so decision makers can keep people safe.”

Scientists will deploy the first gliders in the fleet in early September and continue deploying from different locations throughout the next two to three weeks. Each glider will be deployed for three to eight weeks, collecting data into October.

The underwater gliders can travel thousands of miles and continuously collect and send back ocean data. They can operate for several months at a time and can dive repeatedly to collect three-dimensional ocean observations.

Rutgers University is leading this combined science mission involving all three of the east coast IOOS regions: Northeast, Mid-Atlantic and Southeast. In addition to glider data, the mission will use satellite, moored buoy and coastal radar data. During the mission, the gliders will also collect acoustic data about fish and mammal migrations to improve the understanding of their behaviors.  

Collected glider data will go through NOAA’s National Data Buoy Center to NOAA’s National Weather Service, the U.S. Navy and other data users for modeling. Data from the glider missions will also be public and available on the IOOS Glider Asset Map and at http://www.ndbc.noaa.gov/gliders.php

In addition to NOAA funding, provided through the IOOS regions, other funding sources for the project include the Office of Naval Research, the Environmental Protection Agency, NASA, a private donor from the University of Delaware, and Canada’s Ocean Technology Network.

IOOS is a federal, regional and private sector partnership working to enhance the ability to collect, deliver and use ocean information. IOOS delivers the data and information needed to increase understanding of our ocean and coasts so that decision makers can act to improve safety, enhance the economy, and protect the environment.

After a thoughtful and deliberate review, today NOAA released a report on the National Weather Service’s performance during hurricane/post tropical cyclone Sandy. The report, Hurricane/Post Tropical Cyclone Sandy Service Assessment, reaffirms that the National Weather Service provided accurate forecasts for Sandy, giving people early awareness of the significant storm churning toward the mid-Atlantic and Northeast. The report includes recommendations to improve products and services to fully meet customer and partner needs in the future.

“We found that core partners highly value the National Weather Service and thought the forecasts for Sandy were quite good – forecasters performed well predicting the track of this extremely large and complex storm, which undoubtedly saved lives,” said Peyton Robertson, director of NOAA’s Chesapeake Bay Office and team leader for the Sandy Assessment. “But we also found problems with NOAA’s ability to communicate the impacts associated with storm surge, one of the most significant hazards associated with Sandy.”

The report includes 23 recommendations for service improvements, identifying better storm surge forecasts as the highest priority. Although surge forecasts for Sandy were available two days before the storm, the team found that officials in New York and New Jersey needed information sooner and in more user-friendly, unified formats, including GIS maps and warnings that provide specific local impacts. Among others, the report recommends that NOAA unify public communications of forecast information and expand the use of social science to develop products, services and communication tools to drive public preparedness and response to severe weather.

The National Weather Service has already implemented one of the team’s recommendations and is developing an action plan to ensure that the team’s remaining recommendations become reality. Earlier this year, the National Hurricane Center moved to change its policy to issue forecasts and warnings for dangerous storms like Sandy, even when they are expected to become post-tropical cyclones by landfall. This policy will be in place for the June 1 start of hurricane season.

“I’m committed to implementing these recommendations to give America a National Weather Service that is second to none,” said Dr. Louis Uccellini, director of NOAA’s National Weather Service. “We will achieve better storm surge forecasts, and more accurate and reliable weather forecasts across the board, with increased high performance computing capacity that is planned within the next few years to support improved numerical weather prediction models.”

He explained that the agency’s structure and operations were last modernized two decades ago, and much of the agency’s communications capacity was designed in the 1980s.

This spring Congress passed the Sandy Supplemental Appropriations Act, providing NOAA with unprecedented opportunity to strengthen the National Weather Service. The Act provides $48 million in supplemental funding to the agency’s FY13 budget for Sandy recovery efforts and to improve response and recovery capability for future weather events. The funding will allow the National Weather Service to make critical improvements in high-speed computing, higher resolution weather prediction models and key observation systems, among other projects that will improve the agency’s support to local communities for extreme weather events.

Sandy was a complex storm, resulting in 72 direct deaths across eight states and at least 75 indirect deaths, damages in excess of $50 billion, storm surge in excess of eight feet and up to three feet of snow in some places. At close to 1,000 miles in diameter, it was among the largest storms ever to strike the United States. The storm caused impacts in 24 states.

NOAA formed a team to assess the National Weather Service’s performance before and during the storm, as it does for destructive or deadly weather events. Team members were selected from across NOAA and other government agencies. The team’s charter called for the review of three key areas: the issuance and communication of watches and warnings during Sandy; National Weather Service’s use of the Internet to communicate with the customers and partners; and the development and communication of storm surge forecasts and information across NOAA.

The National Weather Service is the primary source of weather data, forecasts and warnings for the United States and its territories. Working with partners, NOAA’s National Weather Service is building a Weather-Ready Nation to support community resilience in the face of increasing vulnerability to extreme weather.

Polar-orbiting satellite retires

April 10, 2013

POES Satellite in orbit.

After nearly 11 years of helping the National Oceanic and Atmospheric Administration (NOAA) predict weather and climate patterns and save lives in search and rescue operations, NOAA announced today it has turned off the NOAA-17 Polar-Orbiting Environmental Satellite (POES). It was one of NOAA's longest operating spacecraft, which have a typical lifespan of three years.This Image is from the last operational morning orbit of NOAA-17 on May 26, 2007.

After nearly 11 years of helping the National Oceanic and Atmospheric Administration (NOAA) predict weather and climate patterns and save lives in search and rescue operations, NOAA announced today it has turned off the NOAA-17 Polar-Orbiting Environmental Satellite (POES). It was one of NOAA's longest operating spacecraft, which have a typical lifespan of three years. The shutdown will result in no data gap, as NOAA-17 was being used as a back-up satellite and was removed from service after several key systems on board became inoperable.

NOAA will continue operating several POES spacecraft – NOAA-15, NOAA-16, NOAA-18 and NOAA-19 – in addition to the nation’s newest polar-orbiting satellite, Suomi NPP, launched October 28, 2011. NOAA’s POES spacecraft fly a lower, pole to pole orbit capturing atmospheric data from space that feed NOAA’s weather and climate prediction models.

NOAA began the deactivation process of NOAA-17 on February 18, with the final shut down occurring today. Launched in June 2002, NOAA-17 made 55,000 orbits of the globe, traveling more than 1.5 billion miles while collecting huge amounts of valuable temperature, moisture and image data.

“NOAA-17 helped our forecasters see the early development of severe weather from tornadoes and snow storms to hurricanes, including the busiest hurricane season on record - 2005. It also tracked subtle changes in the environment that signaled the onset of drought and wildfire conditions,” said Mary Kicza, assistant administrator of NOAA’s Satellite and Information Service. “NOAA-17’s long life is a credit to the engineers who built and operated it and the technology that sustained it. Although we say farewell to NOAA-17, we still operate a dependable fleet of satellites that continue to provide crucial data.”

NOAA-17 was part of the international Search and Rescue Satellite-Aided Tracking (SARSAT) network of satellites. SARSAT, which began in 1982, has rescued more than 33,000 people worldwide, including more than 7,000 in the United States and its surrounding waters by detecting distress signals from emergency beacons.

Deactivating NOAA-17 also heralds a significant change for polar-orbiting satellite operations worldwide with NOAA now exclusively flying afternoon orbit spacecraft while its key international partner, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), flies mid-morning orbit spacecraft. This results in significant savings for U.S. taxpayers, because sharing data helps produce more accurate and uniform data for forecasters. Through the Initial Joint Polar System agreement, NOAA and EUMETSAT established a shared satellite system by exchanging instruments and coordinating the operations of their polar-orbiting satellites to provide operational meteorological and environmental forecasting and global climate monitoring services worldwide. 

NOAA and its partners at the National Aeronautics and Space Administration (NASA) are continuing to build the next generation of polar-orbiting satellites, the Joint Polar Satellite System (JPSS), which is scheduled to launch the JPSS-1 satellite in 2017.

NOAA’s JPSS represents significant technological and scientific advances for more accurate weather forecasting, helping build a Weather Ready Nation — saving lives and property, while promoting economic prosperity. JPSS provides continuity for critical observations of our vast atmosphere, oceans, land, and cryosphere — the frozen areas of the above planet. NOAA, working in partnership with NASA, ensures an unbroken series of global data for monitoring and forecasting environmental phenomena and understanding our Earth.

2012 was one of the 10 warmest years on record globally

August 6, 2013

State of the Climate in 2012 - report cover.

Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released online today by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA’s National Climatic Data Center in Asheville, N.C., serving as lead editors, was compiled by 384 scientists from 52 countries (highlights, full report). It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments on land, sea, ice, and sky. 

“Many of the events that made 2012 such an interesting year are part of the long-term trends we see in a changing and varying climate — carbon levels are climbing, sea levels are rising, Arctic sea ice is melting, and our planet as a whole is becoming a warmer place," said Acting NOAA Administrator Kathryn D. Sullivan, Ph.D. “This annual report is well-researched, well-respected, and well-used; it is a superb example of the timely, actionable climate information that people need from NOAA to help prepare for extremes in our ever-changing environment."

Conditions in the Arctic were a major story of 2012, with the region experiencing unprecedented change and breaking several records. Sea ice shrank to its smallest “summer minimum” extent since satellite records began 34 years ago. In addition, more than 97 percent of the Greenland ice sheet showed some form of melt during the summer, four times greater than the 1981–2010 average melt extent.

The report used dozens of climate indicators to track and identify changes and overall trends to the global climate system. These indicators include greenhouse gas concentrations, temperature of the lower and upper atmosphere, cloud cover, sea surface temperature, sea-level rise, ocean salinity, sea ice extent and snow cover. Each indicator includes thousands of measurements from multiple independent datasets.

Highlights:

Warm temperature trends continue near Earth’s surface: Four major independent datasets show 2012 was among the 10 warmest years on record, ranking either 8th or 9th, depending upon the dataset used. The United States and Argentina had their warmest year on record. La Niña dissipates into neutral conditions:  A weak La Niña dissipated during spring 2012 and, for the first time in several years, neither El Niño nor La Niña, which can dominate regional weather and climate conditions around the globe, prevailed for the majority of the year.  The Arctic continues to warm; sea ice extent reaches record low: The Arctic continued to warm at about twice the rate compared with lower latitudes. Minimum Arctic sea ice extent in September and Northern Hemisphere snow cover extent in June each reached new record lows. Arctic sea ice minimum extent (1.32 million square miles, September 16) was the lowest of the satellite era. This is 18 percent lower than the previous record low extent of 1.61 million square miles that occurred in 2007 and 54 percent lower than the record high minimum ice extent of 2.90 million square miles that occurred in 1980. The temperature of permafrost, or permanently frozen land, reached record-high values in northernmost Alaska. A new melt extent record occurred July 11–12 on the Greenland ice sheet when 97 percent of the ice sheet showed some form of melt, four times greater than the average melt this time of year. Antarctica sea ice extent reaches record high: The Antarctic maximum sea ice extent reached a record high of 7.51 million square miles on September 26. This is 0.5 percent higher than the previous record high extent of 7.47 million square miles that occurred in 2006 and seven percent higher than the record low maximum sea ice extent of 6.96 million square miles that occurred in 1986. Sea surface temperatures increase: Four independent datasets indicate that the globally averaged sea surface temperature for 2012 was among the 11 warmest on record.  After a 30-year period from 1970 to 1999 of rising global sea surface temperatures, the period 2000–2012 exhibited little trend. Part of this difference is linked to the prevalence of La Niña-like conditions during the 21st century, which typically lead to lower global sea surface temperatures. Ocean heat content remains near record levels: Heat content in the upper 2,300 feet, or a little less than one-half mile, of the ocean remained near record high levels in 2012. Overall increases from 2011 to 2012 occurred between depths of 2,300 to 6,600 feet and even in the deep ocean. Sea level reaches record high: Following sharp decreases in global sea level in the first half of 2011 that were linked to the effects of La Niña, sea levels rebounded to reach record highs in 2012. Globally, sea level has been increasing at an average rate of 3.2 ± 0.4 mm per year over the past two decades. Sea ice concentration reached a new record low in mid-September 2012.

Ocean salinity trends continue: Continuing a trend that began in 2004, oceans were saltier than average in areas of high evaporation, including the central tropical North Pacific, and fresher than average in areas of high precipitation, including the north central Indian Ocean, suggesting that precipitation is increasing in already rainy areas and evaporation is intensifying in drier locations. Tropical cyclones near average: Global tropical cyclone activity during 2012 was near average, with a total of 84 storms, compared with the 1981–2010 average of 89. Similar to 2010 and 2011, the North Atlantic was the only hurricane basin that experienced above-normal activity. Greenhouse gases climb: Major greenhouse gas concentrations, including carbon dioxide, methane, and nitrous oxide, continued to rise during 2012. Following a slight decline in manmade emissions associated with the global economic downturn, global CO2 emissions from fossil fuel combustion and cement production reached a record high in 2011 of 9.5 ± 0.5 petagrams (1,000,000,000,000,000 grams) of carbon , and a new record of 9.7 ± 0.5 petagrams of carbon  is estimated for 2012. Atmospheric CO2 concentrations increased by 2.1 ppm in 2012, reaching a global average of 392.6 ppm for the year. In spring 2012, for the first time, the atmospheric CO2concentration exceeded 400 ppm at several Arctic observational sites. Cool temperature trends continue in Earth’s lower stratosphere: The average lower stratospheric temperature, about six to ten miles above the Earth’s surface, for 2012 was record to near-record cold, depending on the dataset. Increasing greenhouse gases and decline of stratospheric ozone tend to cool the stratosphere while warming the planet near-surface layers.

The 2012 State of the Climate report is peer-reviewed and published annually as a special supplement to the Bulletin of the American Meteorological Society. This year marks the 23rd edition of the report, which is part of the suite of climate services NOAA provides to government, the business sector, academia, and the public to support informed decision-making. The full report can be viewed online.

Explorers discover northernmost Atlantic seeps, deep-sea canyon diversity, off U.S. Northeast

August 2, 2013

Ocean explorers in July on NOAA Ship Okeanos Explorer discovered a wide diversity of seafloor features and communities of life in the largely unexplored deep-sea canyons off the northeast U.S. coast. Now through August 16, as the expedition continues, the public can join the mission as “citizen scientists,” at oceanexplorer.noaa.gov/okeanos, to see live seafloor video and listen as scientists discuss their observations in real time. During the expedition’s July leg, there were nearly 60,000 visits to the live streaming video.

Canyons represent some of the most striking features of the continental slope off the U.S. East Coast and may also be among the most productive areas in the deep sea. Organic matter and nutrient-rich sediments are often concentrated in these areas and strong currents flow through the steep and rugged terrain of the canyons, exposing hard substrates. With an increase in food availability and a variety of different habitat types across varying depths, submarine canyons may contain higher biodiversity and biomass than the adjacent continental slope, and are likely places to observe deep-sea corals, sponges, and other deep-sea marine organisms.

Close-up of methane hydrate observed at a depth of 1,055 meters, near where bubble plumes were detected in previous sonar data. Pressure and cold temperatures create methane hydrate where molecules of natural gas are trapped in an ice-like cage of water molecules. Methane hydrates, a hydrate patch and chemosynthetic communities were seen during this dive, but no active seepage was observed. Seeps were investigated at other locations.

During the July leg of the expedition, the ship’s multibeam sonar detected bubbles rising from the seafloor in several locations about 90 nautical miles southeast of Nantucket, Mass. These water-column plumes were traced to seafloor seeps where explorers observed chemosynthetic communities of life supported by chemicals rather than by sunlight. These are the northernmost seeps detected to date on the U.S. Atlantic margin.

The discoveries are expected to help fisheries and other ocean resource managers make better-informed decisions about how to manage, use and protect the ocean and its resources. Scientists believe the need to learn more about these relatively undisturbed canyon ecosystems is becoming more urgent, particularly as the potential for fishing, marine mining, and hydrocarbon exploration extends into the deep sea.

“We found these little-explored canyons are highly dynamic,” said Tim Shank, a deep-sea biologist from Woods Hole Oceanographic Institution, who participated from ashore. “With each dive of the ROVs (remotely operated vehicles that are undersea robots with cameras), we documented vertical walls with jagged rock failures, collapsed features, and extensive debris fields. Each canyon also appeared to host different biological communities — even different depths within the same canyon would reveal different types of coral and sponge ecosystems.

“As we explored different sides and depth zones of these canyons, we discovered a broad physical and biological diversity,” said Shank. “One canyon would host great animal diversity but low animal abundance and the next canyon would reveal just the opposite. As with any new deep-sea region we explore, we observed many suspected new species and remarkable range extensions of known species. All these observations will be highly informative to design and implement ocean conservation and management strategies in the near future.”

Explorers also observed several instances of new coral life establishing itself, hundreds of skate and cat shark eggs on the seafloor and attached to deep-sea corals, and numerous octopus and squid guarding clutches of eggs. Initial impressions revealed these canyons are hot spots for biodiversity, hosting more than 25 species of corals, and hundreds of associated animals.

Andrea Quattrini, a Ph.D. student from Temple University in Philadelphia, said the expedition provided an immense opportunity for the ocean science and management communities to educate and train the next generation of explorers and deep-sea scientists.

“Their ability to interact with thirty to forty scientists with different areas of expertise, and the free exchange of ideas and discussion, further advanced the exploration and findings by defining new questions and outlining exciting avenues for future research,” she said.

Teachers may take advantage of an Expedition Educational Module at http://go.usa.gov/jn2h. The site provides products tied to the expedition including standards-based lesson plans and ocean-career connections.

Brendan Roark, a geographer from Texas A&M University who participated in the expedition from the ship, believes corals in the area may live as long as 4,000 years. “Deep-sea corals provide a new archive that can help us reconstruct past ocean and climate conditions,” he said. “They grow in a shrub-like fashion and most importantly, they deposit annual growth rings much like trees do. Because of their extremely long life spans, they may develop high resolution records of oceanographic and climate variability.”

An international team of more than 40 scientists and students – partners from multiple federal agencies and academic institutions – located mostly on shore, participated in the expedition’s first leg, receiving data and live video from the ship via telepresence-technology, using satellite and Internet pathways. The science team included several scientists at sea and others in Washington D.C., 12 U.S. states and two nations.

Scientists on the expedition’s July leg mapped 7,209 square kilometers of seafloor as they explored areas between 560 meters (1,837 feet) and 2,135 meters (7,005 feet) deep, in and between Block, Alvin, Atlantis, Veatch and Hydrographer canyons. The second leg is exploring Welker, Oceanographer, Lydonia, Nygren and Heezen canyons as well as Mytilus Seamount, one of the easternmost seamounts along the submerged northeast New England Seamount Chain within the U.S. Exclusive Economic Zone. Very little information exists for these areas. Scientists on both expedition legs are obtaining valuable data using the latest technologies including state-of-the-art multibeam sonar and NOAA’s new 6,000-meter ROV, Deep Discoverer, coupled with the Seirios camera sled and lighting platform.

Federal agencies remapping coastal areas damaged by Hurricane Sandy

August 20, 2013

A day after the administration released the Hurricane Sandy Rebuilding Task Force progress report, three federal agencies have announced plans for remapping parts of the East Coast, where Hurricane Sandy altered seafloors and shorelines, destroyed buildings, and disrupted millions of lives last year.

NOAA, the U.S. Geological Survey, and the U.S. Army Corps of Engineers are using emergency supplemental funds provided by Congress to survey coastal waters and shorelines, acquiring data that will update East Coast land maps and nautical charts.

Using ships, aircraft, and satellites, the agencies will measure water depths, look for submerged debris, and record altered shorelines in high priority areas from South Carolina to Maine, as stipulated by Congress in the Disaster Relief Appropriations Act of 2013. The areas to be remapped will be based on their relative dangers to navigation, effects from the storm, and discussions with state and local officials as well as the maritime industry.

“Our approach is to map once, then use the data for many purposes,” said NOAA Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “Under the Ocean and Coastal Mapping Integration Act, NOAA and its federal partners are taking a 'whole ocean' approach to get as much useful information as possible from every dollar invested to help states build more resilient coastlines.”

The data, much of which will be stored at NOAA’s National Geophysical Data Center, and through NOAA’s Digital Coast, will be open to local, state, and federal agencies as well as academia and the general public. The information can be applied to updating nautical charts, removing marine debris, replenishing beaches, making repairs, and planning for future storms and coastal resilience.

The three federal agencies are collaborating for greater topographic and hydrographic coverage and to promote efficiency. Earlier this year, a NOAA navigation response team surveyed the waters around Liberty Island and Ellis Island in New York harbor, measuring water depths and searching for debris that could cause a danger to navigation. Also, NOAA Ship Thomas Jefferson began surveying the approaches to the Delaware Bay in June.

NOAA plans to contract with commercial firms for additional hydrographic survey projects and high resolution topographic and bathymetric elevation data and imagery in the region.

The U.S. Geological Survey will collect very high-resolution elevation data to support scientific studies related to the hurricane recovery and rebuilding activities, watershed planning and resource management. USGS will collect data in coastal and inland areas depending on their hurricane damages and the age and quality of existing data. The elevation data will become part of a new initiative, called the 3D Elevation Program, to systematically acquire improved, high-resolution elevation data across the United States.

“The human deaths and the powerful landscape-altering destruction caused by Hurricane Sandy are a stark reminder that our nation must become more resilient to coastal hazards,” said Kevin Gallagher, associate director for Core Science Systems at USGS. "Sandy's most fundamental lesson is that storm vulnerability is a direct consequence of the elevation of coastal communities in relation to storm waves. Communities will benefit greatly from the higher resolution and accuracy of new elevation information to better prepare for storm impacts, develop response strategies, and design resilient and cost-efficient post-storm redevelopment."

The Army Corps of Engineers and its Joint Airborne Lidar Bathymetry Technical Center of Expertise are covering particular project areas in Massachusetts, Virginia, and New Jersey. They will coordinate operations, research, and development in airborne lidar bathymetry and complementary technologies for USACE, NOAA, and the U.S. Navy.

Preliminary U.S. damage estimates are near $50 billion, making Sandy the second-costliest cyclone to hit the United States since 1900. There were at least 147 direct deaths recorded across the Atlantic basin due to Sandy, with 72 of these fatalities occurring in the mid-Atlantic and northeastern United States. This is the greatest number of U.S. direct fatalities related to a tropical cyclone outside of the southern states since Hurricane Agnes in 1972.

NOAA confirms wreck is lost 19th century U.S. Coast Survey steamer

August 27, 2013

In 1852, W.A.K. Martin painted this picture of the Robert J. Walker. The painting, now at the Mariner's Museum in Newport News, Virginia, is scheduled for restoration.

More than 153 years after it was lost in a violent collision at sea, government and university maritime archaeologists have identified the wreck of the ship Robert J. Walker, a steamer that served in the U.S. Coast Survey, a predecessor agency of NOAA.

The Walker, while now largely forgotten, served a vital role as a survey ship, charting the Gulf Coast ? including Mobile Bay and the Florida Keys ? in the decade before the Civil War. It also conducted early work plotting the movement of the Gulf Stream along the Atlantic Coast.

Twenty sailors died when the Walker sank in rough seas in the early morning hours of June 21, 1860, ten miles off Absecon Inlet on the New Jersey coast. The crew had finished its latest surveys in the Gulf of Mexico and was sailing to New York when the Walker was hit by a commercial schooner off New Jersey. The side-wheel steamer, carrying 66 crewmembers, sank within 30 minutes. The sinking was the largest single loss of life in the history of the Coast Survey and its successor agency, NOAA.

“Before this identification was made, the wreck was just an anonymous symbol on navigation charts,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “Now, we can truly honor the 20 members of the crew and their final resting place. It will mark a profound sacrifice by the men who served during a remarkable time in our history.”

Built in 1847, the Walker was one of the U.S. government’s first iron-hulled steamers, and was intended for the U.S. Revenue Service, the predecessor of the United States Coast Guard. Instead, the Walker and some of its sister steamers were sent to the U.S. Coast Survey.
Admiral Robert J. Papp, commandant of the Coast Guard, said that Walker represented the transition from sail to steam for government vessels, “reflecting the enduring need of the United States to harness the power of new technology to promote its maritime interests.”

“Coast Guardsmen are always saddened by the loss of life at sea and especially so when those lost were working to make the lives of other mariners safer by charting the waters of the United States,” Papp said.

The U.S. Coast Survey is NOAA’s oldest predecessor organization, established by President Thomas Jefferson in 1807 to survey the coast and produce the nation’s nautical charts. In 1860, as the Civil War approached, the Coast Survey redoubled efforts to produce surveys of harbors strategically important to the war effort along the Gulf and Atlantic coasts.

The New York Herald, in reporting the Walker’s loss on June 23, 1860, noted that a “heavy sea was running, and many of the men were doubtless washed off the spars and drowned from the mere exhaustion of holding on, while others were killed or stunned on rising to the surface by concussion with spars and other parts of the wreck.”

NOAA is able to confirm the identity of the Walker using various criteria, including the ship's unique paddlewheel flanges.

The Walker wreck site initially was discovered in the 1970s by a commercial fisherman. The wreck's identity has been a mystery despite being regularly explored by divers. Resting 85 feet underwater, the vessel’s identity was confirmed in June as part of a private-public collaboration that included research provided by New Jersey wreck divers; Joyce Steinmetz, a maritime archaeology student at East Carolina University; and retired NOAA Corps Capt. Albert Theberge, chief of reference for the NOAA Central Library.

While in the area to conduct hydrographic surveys after Hurricane Sandy for navigation safety, NOAA Ship Thomas Jefferson sailed to the wreck site and deployed its multibeam and sidescan sonar systems. Hydrographers searched likely locations based on analysis of historical research by Vitad Pradith, a physical scientist with NOAA’s Office of Coast Survey.

A NOAA Maritime Heritage diving team, on a separate Hurricane Sandy-related mission in the area, was able to positively identify the Walker. Key clues were the size and layout of the iron-hulled wreck, and its unique engines, rectangular portholes, and the location of the ship, which was found still pointing toward the Absecon lighthouse, the final destination of a desperate crew on a sinking vessel.

“The identification of Walker is a result of excellent collaboration with the local community,” said James P. Delgado, director of maritime heritage for NOAA’s Office of National Marine Sanctuaries. “We look forward to working with our local partners to share Walker’s story with the public in a manner that both promotes educational dive tourism and protects this nationally significant wreck and gravesite.”

NOAA’s intent is not to make the wreck a sanctuary or limit diving, but to work with New Jersey’s wreck diving community to better understand the wreck and the stories it can tell.

“We want to enhance the dive experience and support the dive industry with enhanced access to this wreck,” Delgado said. “New Jersey is home to some of the most accomplished wreck divers who not only understand history and wrecks, but who have also been in the forefront of wreck exploration. We look forward to working with them on the Walker.”

NOAA’s Marine Debris Program announced today that it provided $967,000 through NOAA’s Restoration Center to support locally driven, community-based marine debris prevention and removal projects. Eleven groups across the country received funding to remove derelict fishing nets, litter, lumber, tires and other harmful marine debris from shorelines and coastal waters.

“Marine debris plagues coastlines all over the country, and these communities have the expertise and motivation to address it,” said Nancy Wallace, Marine Debris Program director. “We are proud to support them as they work to mitigate impacts and address the damage marine debris has caused.”

The projects typically last for 24 months and create long-term ecological improvements for coastal habitat, waterways and wildlife, including migratory fish.

The projects were chosen from a pool of 46 applications submitted by non-governmental organizations, tribes, academia and local government agencies. The combined request from all applications totaled nearly $5 million, demonstrating the widespread need to address marine debris across the country. With this program, NOAA has funded 76 marine debris removal projects and removed more than 3,800 metric tons of marine debris from our oceans and Great Lakes since 2006.

This year’s projects include:

Alabama: The Dauphin Island Sea Lab will remove derelict vessels and address habitat impairment in the Dog River Watershed in Mobile. ($99,766) Alaska: The Alaska Marine Stewardship Foundation will conduct marine debris cleanups in five communities in the Bering Sea: Port Heiden, Nelson Lagoon, Nikolski, St. George and Savoonga. ($210,000) The Sitka Sound Science Center will perform cleanups of tsunami debris from Japan that impacted Alaskan coastlines. ($120,000) California: The Wiyot Tribe of the Humboldt Bay region will remove large marine debris from the within bay and on Indian Island, a National Historic Landmark known for its importance as the site of the Wiyot World Renewal ceremony. ($125,000)Florida: The Coastal Cleanup Corporation will remove plastics, glass, Styrofoam, rubber and discarded fishing gear from sea turtle nesting sites within Biscayne National Park. ($16,953) Hawaii: The Hawaii Wildlife Fund will continue its work to remove marine debris from the shoreline of Big Island of Hawaii, focusing on the Ka‘u coast. ($45,000) The Hawaii Department of Land and Natural Resources will remove debris from Kaho‘olawe. ($100,530) New York: Hofstra University will remove debris from one of the last remaining natural salt marshes in Nassau County, in collaboration with Long Beach School District and Town of Hempstead. ($75,000) North Carolina: The North Carolina Coastal Federation will implement a pilot program working with commercial fishermen to remove derelict crab pots and repurpose them as artificial oyster reefs. ($35,576)Puerto Rico: The Corporation for The Conservation of The San Juan Bay Estuary will remove litter from Condado Lagoon, one of two natural lagoons in Puerto Rico. ($40,000) Washington: The Northwest Straits Foundation will continue its longstanding efforts to remove derelict fishing nets from Puget Sound and surrounding marine waters. ($99,995)

NOAA’s Restoration Center is now accepting applications for the next funding cycle and applications are due November 1. For more information, visit http://www.habitat.noaa.gov/funding/marinedebris.html.

Atlantic hurricane season on track to be above-normal

NOAA issued its updated Atlantic hurricane season outlook today saying the season is shaping up to be above normal with the possibility that it could be very active. The season has already produced four named storms, with the peak of the season – mid-August through October – yet to come.
“Our confidence for an above-normal season is still high because the predicted atmospheric and oceanic conditions that are favorable for storm development have materialized,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, a division of the National Weather Service. “Also, two of the four named storms to-date formed in the deep tropical Atlantic, which historically is an indicator of an active season.”
The conditions in place now are similar to those that have produced many active Atlantic hurricane seasons since 1995, and include above-average Atlantic sea surface temperatures and a stronger rainy season in West Africa, which produces wind patterns that help turn storm systems there into tropical storms and hurricanes.
The updated outlook calls for a 70 percent chance of an above-normal season. Across the Atlantic Basin for the entire season – June 1 to November 30 – NOAA’s updated seasonal outlook (which includes the activity to date of tropical storms Andrea, Barry, Chantal, and Dorian) projects a 70 percent chance for each of the following ranges:

13 to 19 named storms (top winds of 39 mph or higher), including 6 to 9 hurricanes (top winds of 74 mph or higher), of which3 to 5 could be major hurricanes (Category 3, 4 or 5; winds of at least 111 mph)

These ranges are above the 30-year seasonal averages of 12 named storms, six hurricanes and three major hurricanes.

The updated outlook is similar to the pre-season outlook issued in May, but with a reduced expectation for extreme levels of activity. Motivating this change is a decreased likelihood that La Niña will develop and bring its reduced wind shear that further strengthens the hurricane season. Other factors are the lack of hurricanes through July, more variability in the wind patterns across the tropical Atlantic Ocean and slightly lower hurricane season model predictions. In May, the outlook called for 13-20 named storms, 7-11 hurricanes and 3-6 major hurricanes.

“The peak of the hurricane season is almost upon us and it’s important to remain prepared for hurricanes through November," said Joe Nimmich, FEMA Associate Administrator for Response and Recovery. "Make sure to review your family emergency plan, check that your emergency kit is stocked and consider insurance options.

NOAA Corps Capt. Harris B. Halverson today assumed command of the NOAA Aircraft Operations Center in Tampa, Fla. The center is home to most of NOAA’s environmental research, reconnaissance and survey aircraft, including the agency’s “hurricane hunter” planes.

Halverson relieved Capt. Randall J. TeBeest, who had served as the center’s commanding officer since July 2011. The Aug. 2 change-of-command ceremony was presided over by Rear Adm. David A. Score, deputy director for operations for the NOAA Office of Marine and Aviation Operations.

“Capt. TeBeest’s service as the center’s commanding officer has been exemplary, and we thank him for his dedication and leadership,” said Score. “NOAA’s aircraft operations will also be well-served by Capt. Halverson, a proven leader who is committed to the safety and success of every mission NOAA flies on behalf of the nation.” Halverson was born in Minneapolis and was raised both in Minnesota and the Tampa Bay area. Upon graduation from Lakewood High School in St. Petersburg, Fla., in 1984, he enlisted in the U.S. Marine Corps, and was accepted into the Naval Academy Preparatory School. He attended the U.S. Naval Academy and graduated in 1990 with a degree in oceanography.

He later completed U.S. Navy flight training and was assigned to Patrol Squadron 16 in Jacksonville, Fla., where he flew P-3C Orion anti-submarine aircraft. He completed two six-month deployments as aircraft commander and as Chief of Naval Operations special project (Beartrap) mission commander. Halverson was nominated for Naval Aviator of the Year in 1997.
In 1998, Halverson transferred to Patrol Squadron 30, where he instructed newly designated naval aviators until he completed an inter-service transfer as a lieutenant commander to the NOAA Commissioned Officer Corps in 2000. Initially assigned to the center, he qualified as hurricane aircraft commander and received the NOAA Office of Marine and Aviation Operations Employee of the Year Award for 2003. Halverson also managed a project to install a tail Doppler radar system on NOAA’s Gulfstream IV-SP aircraft. He has piloted NOAA hurricane hunter aircraft into more than 30 tropical cyclones, including Hurricane Sandy.

In 2008, Halverson assumed the duties of executive officer of NOAA Research and was promoted in 2009 to the senior executive service position of acting director of NOAA’s Office of Ocean Exploration and Research. He returned to  the center in 2010 to serve as chief of its operations branch.

Halverson is a graduate of both the Naval Postgraduate School’s Aviation Safety Program and Harvard’s Senior Executive Fellows Program. He lives in Tampa with his wife and two children.

Located at MacDill Air Force Base in Tampa, the Aircraft Operations Center is part of the NOAA Office of Marine and Aviation Operations, which includes civilians and officers of the NOAA Corps, one of the nation’s seven uniformed services.

Human influences are having an impact on some extreme weather and climate events, according to the report “Explaining Extreme Events of 2012 from a Climate Perspective” released today by the Bulletin of the American Meteorological Society. Overall, 18 different research teams from around the world contributed to the peer-reviewed report that examined the causes of 12 extreme events that occurred on five continents and in the Arctic during 2012. Scientists from NOAA served as three of the four lead editors on the report.
The report shows that the effects of natural weather and climate fluctuations played a key role in the intensity and evolution of the 2012 extreme events. However, in some events, the analyses revealed compelling evidence that human-caused climate change, through the emission of heat-trapping gases, also contributed to the extreme event.

“This report adds to a growing ability of climate science to untangle the complexities of understanding natural and human-induced factors contributing to specific extreme weather and climate events,” said Thomas R. Karl, L.H.D, director of NOAA’s National Climatic Data Center (NCDC). “Nonetheless, determining the causes of extreme events remains challenging.”

In addition to investigating the causes of these extreme events, the multiple analyses of four of the events — the warm temperatures in the United States, the record-low levels of Arctic sea ice, and the heavy rain in both northern Europe and eastern Australia — allowed the scientists to compare and contrast the strengths and weaknesses of their various methods of analysis. Despite their different strategies, there was considerable agreement between the assessments of the same events.

Thomas Peterson, Ph.D., principal scientist at NOAA’s NCDC and one of the lead editors on the report, said, “Scientists around the world assessed a wide variety of potential contributing factors to these major extreme events that, in many cases, had large impacts on society. Understanding the range of influences on extreme events helps us to better understand how and why extremes are changing."

Key findings include:

Location and type of events analyzed in the Paper.

Heat Wave and Drought in United States:

Human-induced climate change had little impact on the lack of precipitation in the central United States in 2012.The 2012 spring and summer heat waves in the U.S. can be mainly explained by natural atmospheric dynamics, however, human-induced climate change was found to be a factor in the magnitude of warmth and was found to have affected the likelihood of such heat waves.  For example: High temperatures, such as those experienced in the U.S. in 2012 are now likely to occur four times as frequently due to human-induced climate change.Approximately 35 percent of the extreme warmth experienced in the eastern U.S. between March and May 2012 can be attributed to human-induced climate change.  

Hurricane Sandy Inundation Probability:

The record-setting impacts of Sandy were largely attributable to the massive storm surge and resulting inundation from the onshore-directed storm path coincident with high tide. However, climate-change related increases in sea level have nearly doubled today’s annual probability of a Sandy-level flood recurrence as compared to 1950. Ongoing natural and human-induced forcing of sea level ensures that Sandy-level inundation events will occur more frequently in the future from storms with less intensity and lower storm surge than Sandy. 

Arctic Sea Ice:

The extremely low Arctic sea ice extent in summer 2012 resulted primarily from the melting of younger, thin ice from a warmed atmosphere and ocean. This event cannot be explained by natural variability alone. Summer Arctic sea ice extent will continue to decrease in the future, and is expected to be largely absent by mid-century.  

Global Rainfall Events:

The unusually high amount of summer rainfall in the United Kingdom in 2012 was largely the result of natural variability. However, there is evidence that rainfall totals are influenced by increases in sea surface temperature and atmospheric moisture which may be linked to human influences on climate.The magnitude of the extreme rainfall experienced over southeastern Australia between October 2011 and March 2012 was mainly associated with La Niña conditions. However, the likelihood of above-average precipitation during March was found to have increased by 5 percent to 15 percent because of human influences on the climate. Extreme rainfall events such as the December 2011 two-day rainfall in Golden Bay, New Zealand, are more likely to occur due to a 1 percent to 5 percent increase in available moisture resulting from increased levels of greenhouse gases in the atmosphere.The July 2012 extreme rainfall events in North China and southwestern Japan were mainly due to natural variability. 

The report was edited by Peterson, along with Martin P. Hoerling, NOAA’s Earth System Research Laboratory; Peter A. Stott, UK Met Office Hadley Centre and Stephanie C. Herring of NCDC and written by 78 scientists from 11 countries. View the full report online.

National Weather Service more than doubles computing capacity

July 29, 2013

This is the Hurricane Weather Research and Forecasting (HWRF) model showing the Tropical Storm Flossie precipitation forecast for the Hawaiian Islands on July 29, 2013.

This is the Hurricane Weather Research and Forecasting (HWRF) model showing the Tropical Storm Flossie precipitation forecast for the Hawaiian Islands on July 29, 2013. HWRF is one of the sophisticated numerical computer models now being run on NOAA's new supercomputers.

Whizzing through 213 trillion calculations per second, newly upgraded supercomputers of NOAA’s National Weather Service are now more than twice as fast in processing sophisticated computer models to provide more accurate forecasts further out in time. And as the hurricane season ramps up, forecasters will be armed with an enhanced hurricane model that will improve track and intensity forecasts.

The scientific data and insights that these newly upgraded supercomputers will provide are essential to help government officials, communities, and businesses better understand and manage the risks associated with extreme weather and water events. In support of the president’s Climate Action Plan, the administration will continue to take steps like this to analyze and predict climate variability amid an increasing number of extreme natural events affecting the nation.

“These improvements are just the beginning and build on our previous success. They lay the foundation for further computing enhancements and more accurate forecast models that are within reach,” said Louis W. Uccellini, Ph.D., director of NOAA’s National Weather Service. “These upgrades are a game-changer for the entire public and private weather industry. In addition to the benefits to our own forecasters and products, we will provide our private sector partners with better information to empower them to enhance their services.”

Nicknamed “Tide,” the supercomputer in Reston, Va., and its Orlando-based backup named “Gyre,” are operating with 213 teraflops (TF) — up from the 90 TF with the computers that preceded them. This higher processing power allows the National Weather Service to implement an enhanced Hurricane Weather Research and Forecasting (HWRF) model.

"These forecasting advances can save lives,” said U.S. Sen. Bill Nelson, who helped get funding to add even more capacity to the supercomputer. “It's going to allow for better tracking of life-threatening storms and more accurately predict when and where they'll hit, and with what intensity."

With improved physics and a storm-tracking algorithm, the model has displayed up to a 15 percent improvement in both track and intensity forecasts, compared to last year's version of the model. The upgraded HWRF is also capable of processing real-time data collected from the inner core of a tropical system by the tail Doppler radar attached to NOAA’s P3 hurricane hunter aircraft, data which are expected to produce even greater forecast improvements.

“Next comes the quantum leap,” added Uccellini. Following this round of long-planned upgrades, funding requested in the FY 2014 President’s Budget, in addition to funding provided to NOAA by Congress in the spring of 2013 as part of the Hurricane Sandy emergency supplemental appropriations bill, would increase computing power even further to 1,950 TF by summer 2015. “That gives us the necessary computer power to run an enhanced version of our primary forecast model, the Global Forecast System,” said Uccellini.

"Given recent events like the tornado in Moore, Oklahoma or Superstorm Sandy, federal weather resources and personnel should be considered vital national assets. These upgrades assure world-class capabilities and a continued pathway to keep American lives and property safer," said J. Marshall Shepherd Ph.D., president of the American Meteorological Society and Professor at the University of Georgia. "As a father of two children and a scientist that understands looming weather threats, I take comfort in these developments."

Investments in supercomputing power for weather prediction are another step in NOAA’s efforts to build a Weather-Ready Nation. NOAA’s Weather-Ready Nation initiative, launched nearly two-years ago, has resulted in improvements in products, services and the way information is communicated to the public and partners. These improvements increase resilience to severe weather and reduce the potential of significant societal and economic impacts from severe weather.  A Weather-Ready Nation is a society that is prepared for, and responds effectively to, weather-related events.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.

Contiguous U.S. wetter, warmer-than-average during July; 5th wettest and 30th warmest July on record

July Extreme Weather/Climate Events
Climate Highlights — JulyThe average temperature for the contiguous U.S. during July was 74.3°F, 0.8°F above the 20th century average, and ranked as the 30th warmest such month on record. The western U.S. was warmer than average, where Idaho, Nevada, Oregon, and Utah each had a top ten warm month. Several cities, including Salt Lake City, Utah, and Reno, Nev., had their warmest July on record. Seven states across the Northeast also had July temperatures ranking among the ten warmest on record, including Massachusetts and Rhode Island, each of which had a record warm July. Locations from the Central and Southern Plains into the Southeast were cooler than average. Four states — Alabama, Arkansas, Mississippi, and Tennessee — had July temperatures that were among the ten coolest on record. The Alaska statewide average temperature was 1.7°F above the 1971-2000 average and ranked as the fifth warmest July on record for the state. Anchorage had its fourth warmest July, and the city set a record with 14 consecutive days above 70°F. The nationally-averaged July precipitation total of 3.47 inches was 0.71 inch above average and was the 5th wettest July on record for the contiguous United States. Wetter-than-average conditions stretched from California, through the Southwest and Plains, and along the Eastern Seaboard. In the Southwest, seasonal monsoonal flow brought above average precipitation to several states, where Arizona and California both had July precipitation totals ranking among their ten wettest. During this time of year in parts of the Southwest, even light precipitation can result in above-average monthly totals but have minimal impacts on alleviating drought conditions. In the East, 13 states had one of their ten wettest Julys on record, with the highest precipitation totals across the Southeast. Florida had its wettest July on record, with 12.38 inches of rainfall, 4.91 inches above average. The above-average precipitation in the Southeast resulted in widespread flooding and significant damage to crops. The Northwest was particularly dry. Oregon had its driest July on record with only 0.03 inch of rainfall accumulating, 0.41 inch below average. Washington had its eighth driest July. Below-average precipitation was also observed in the Upper Mississippi River Valley, where Iowa had its tenth driest July. According to the July 30 U.S. Drought Monitor report, 45.6 percent of the contiguous U.S experienced drought conditions, up slightly from the beginning of July. Drought remained entrenched throughout much of the West and in parts of the Central and Southern Plains, and drought expanded into parts of the Lower Mississippi River Valley and Midwest. Over 20 percent of Alaska was in drought at the end of July, with severe drought developing in central parts of the state. Based on NOAA's Residential Energy Demand Temperature Index (REDTI), the contiguous U.S. temperature-related energy demand during July was above average and ranked as the 41st highest July value in the 119-year period of record.The components of the U.S. Climate Extremes Index (USCEI) that examine extremes in warm night time temperatures, the spatial extent of wetness and drought, and extremes in days with rainfall were all above average. When combined with the other components of the index, the USCEI, as a whole, was only slightly above average. The USCEI is an index that tracks the highest and lowest 10 percent of extremes in temperature, precipitation, tropical cyclones, and drought across the contiguous United States.On a local basis, the number of record warm daily highs and lows (2560) during July was roughly the same as the number of record cool daily highs and lows (2846), although there were slightly more cool records. Climate Highlights — year-to-date (January – July)The year-to-date contiguous U.S. temperature of 51.8°F was 0.5°F above the 20th century average and tied with 1952 as the 42nd warmest January–July on record. Above-average temperatures were observed in the West and Northeast, where California, New Hampshire, and Vermont had one of their top ten warmest year-to-date periods. Below-average temperatures stretched from the Northern Plains to the Southeast. The year-to-date contiguous U.S. precipitation total of 19.14 inches was 1.54 inches above average and tied with 1997 as the 22nd wettest January–July on record. However, rainfall was not evenly distributed across the country. Dry precipitation extremes were observed in the West and wet precipitation extremes were observed in the East. California, Idaho, Nevada, and Oregon each had a top ten dry year-to-date period. California's precipitation total of 4.58 inches was record low for the seven-month period at 9.82 inches below average, and 1.69 inches less than the previous record dry January–July of 1898. Above-average precipitation was observed across most locations east of the Rockies, with ten states having one of their ten wettest year-to-date periods. Michigan was record wet with 24.35 inches of precipitation, 6.92 inches above average, and 2.30 inches above the previous record wet January–July of 1950. Several cities, from Fargo, North Dakota to Greenville, South Carolina, had a record wet January–July. Based on NOAA's Residential Energy Demand Temperature Index (REDTI), the contiguous U.S. temperature-related energy demand during January–July was below average and ranked as the 47th lowest January–July value in the 119-year period of record.The components of the USCEI that examine extremes in the spatial extent of drought, as well as 1-day precipitation totals and days with rainfall were much above average for the year-to-date. When combined with the other components of the index, the USCEI, as a whole, was only slightly above average.

Regional Highlights:These regional summaries were provided by the six Regional Climate Centers and reflect conditions in their respective regions. These six regions differ spatially from the nine climatic regions of the National Climatic Data Center.

Northeast Region: (Information provided by the Northeast Regional Climate Center)The Northeast continued to be warmer than normal in July. With an average temperature of 72.4 degrees F (22.4 degrees C), it was 2.5 degrees F (1.4 degrees C) above normal and the 12th warmest July on record. All twelve states were warmer than normal with Rhode Island and Massachusetts reporting their warmest July in 119 years. Departures for those two states were +4.6 degrees F (+2.6 degrees C) and +4.5 degrees F (+2.5 degrees C) respectively. Vermont had its 2nd warmest July on record at +4.1 degrees F (+2.3 degrees C) while Connecticut (+4.3 degrees F or +2.4 degrees C) and New Hampshire (+3.5 degrees F or +1.9 degrees C) saw their 3rd warmest July. New Jersey had its 5th warmest July on record at +3.0 degrees F (+1.7 degrees C) and Delaware reported its 6th warmest July with +2.4 degrees F (+1.3 degrees C). July 2013 ranked among the top 20 warmest in New York, Maine, Pennsylvania, and Maryland. Departures for those states ranged from +2.6 degrees F (+1.4 degrees C) to +1.4 degrees F (+0.8 degrees C). West Virginia, while warmer than normal, was the coolest state at +0.6 degrees F (+0.3 degrees C).The wet conditions of June spilled over into July for most Northeast states. The region ended the month with 5.14 inches (130.6 mm) of precipitation, 121 percent of normal, making it the 15th wettest July since 1895. Connecticut and Rhode Island were the dry states at 91 percent of normal. Vermont was the wettest state, receiving 143 percent of normal precipitation, making it the 7th wettest July on record. New Hampshire received 135 percent of normal precipitation, making it the 8th wettest July, while West Virginia received 126 percent of normal, their 10th wettest July. With departures of 126 percent of normal and 123 percent of normal, Maine and New York ranked this July among their top 15 wettest. Departures for the other states ranged from 127 percent of normal in Delaware to 101 percent of normal in Massachusetts. At the start of July, lingering abnormal dryness was located along the Pennsylvania-West Virginia border, but by mid-month, ongoing abundant precipitation eased dryness in that area. Downpours were common throughout July. For instance, on the 9th, 2.5 inches (63.50 mm) of rain fell in 20 minutes in Orleans County, Vermont. On the 17th, Caribou, Maine, had its wettest July day on record with 3.81 inches (96.77 mm) of rain. And in Philadelphia, Pennsylvania, July 28, 2013 became the rainiest day on record when 8.02 inches (203.71 mm) of rain fell, most of it in a four-hour period. The city also reported its wettest July on record with 13.24 inches (336.30 mm) of precipitation. The excess precipitation had many consequences. Heavy rain during June left waterways already running high in July. Flash flooding occurred in parts of every Northeast state. Roads were washed out and closed, homes and businesses were flooded, cars were stranded, and people were evacuated and rescued from the rising waters. Also, heavy rains flushed excessive nitrogen into the waters of estuaries on the south side of Long Island, New York, helping cause the first summer brown tide since 2008. Substantial runoff caused Lake Champlain to rise to a record high summer level, 99.68 feet (30.38 m), on July 7-8. In addition, the precipitation affected agriculture. In New Jersey, farmers in Burlington County reported the wet weather caused disease in vegetables while farmers in Cape May County reported some squash fields were completely lost due to excess moisture. July also had its share of tornadoes. Seven EF-0 tornadoes and five EF-1 tornadoes touched down in the Northeast. The EF-0s primarily uprooted and topped trees while the EF-1s also caused some structural and crop damage. In addition, a gustnado in New Jersey on the 22nd caused some damage and multiple waterspouts were spotted on Lakes Erie and Ontario on the 29th. One other highlight of the month was a hot, humid air mass that set up over the region from July 14 through 20. On the 19th, New York City and Westchester County set an all-time peak electric usage, 13,322 MW. At the Inner Harbor in Baltimore, Maryland, the warm temperatures contributed to an overgrowth of bacteria and a lack of oxygen in the waters. The harbor's water turned a milky green and hundreds of fish died. Philadelphia, Pennsylvania, set a record for longest string of days at or above 70 degrees F (21.1 degrees C) with 30 such days from June 24 through July 23. For more information, please go to the Northeast Regional Climate Center Home Page.Midwest Region: (Information provided by the Midwest Regional Climate Center)July temperatures in the Midwest ranged from near normal to 3 degrees F (2 C) below normal. The near normal temperatures stretched across the upper Midwest and then southward into Ohio. Slightly cooler than normal temperatures were recorded in Iowa, Missouri, Illinois, Indiana, and Kentucky. The month began with cool temperatures and then warmed to well above normal mid-month before cooling to well below normal in the last week of July. More than 900 daily record low temperatures were set or tied in the last eight days of the month. Many of these records were also the record lows for the entire month including more than two dozen on the 28th alone.July precipitation ranged from less than 25 percent of normal in western Iowa to about twice normal in parts of southern Missouri, southern Illinois, Kentucky, Ohio, Upper Michigan, and in the arrowhead of Minnesota. A few cities in western Iowa set new July precipitation records with less than a quarter inch (6 mm). The dryness in Iowa was a drastic change from the wettest spring on record for the state.The Midwest began the month nearly drought free but dryness in the western states, Minnesota, Iowa, and Missouri, has led to expanding areas of moderate drought and abnormally dry conditions in the US Drought Monitor. Moderate drought expanded only slightly from under one percent to just over two percent of the region. Abnormally dry conditions grew much more going from about two percent to nearly 19 percent of the region. The dryness has started to show in crop condition reports but has been mitigated somewhat by the moist soils from earlier rains and cooler than normal conditions.Severe weather reports were spread across the region with Ohio having the highest concentration. Just a handful of days in July went without a Midwest severe weather report including a three-day stretch in mid-month. July tornadoes touched down in six Midwest states sparing only Iowa, Illinois, and Michigan. Tornado numbers across the US in 2013 were well below normal and the same departure applied to the Midwest. The cooler weather in July has been good because the crops have seen little heat stress but the accumulation of growing degree days has been slowed. Because planting was later than normal and degree day accumulation has also behind normal, concerns about a damaging fall freeze are increasing because the crops will likely mature and dry down later than normal in 2013.For details on the weather and climate events of the Midwest, see the weekly summaries in the Midwest Climate Watch page.Southeast Region: (Information provided by the Southeast Regional Climate Center)Mean temperatures were variable across the Southeast in July. The greatest departures were found across much of Alabama, Georgia, South Carolina, and South Florida, where monthly temperatures were 2 to 3 degrees F (1.1 to 1.6 degrees C) below average. Temperatures were also below average across much of Puerto Rico and the U.S. Virgin Islands. In contrast, monthly temperatures were 1 to 2 degrees F (0.5 to 1.1 degrees C) above average across much of Virginia and parts of eastern North Carolina. In particular, minimum temperatures in these areas were exceptionally warm. For the month, the mean minimum temperature ranked as the third warmest in Washington D.C. and Richmond, VA in records extending back to 1871 and 1887, respectively. For the second consecutive month, there was a relative absence of extreme heat across much of the Southeast region. In fact, several locations recorded monthly maximum temperature departures of 5 to 7 degrees F (2.8 to 3.9 degrees C) below average. In addition, more than 200 daily low maximum temperature records were tied or broken across the region. On the 17th of the month, Miami, FL recorded a maximum temperature of 78 degrees F (25.6 degrees C), which was only 1 degree F (0.5 degrees C) shy of the all-time daily low maximum temperature for July in a record extending back to 1895.For the second consecutive month, precipitation was much above average across a large portion of the Southeast region. The wettest locations were found across the western Panhandle of Florida, the Upstate of South Carolina, and western North Carolina, where monthly totals exceeded 20 inches (508 mm) in places, or more than 300 percent of normal. Precipitation was also above average across Puerto Rico and much of the U.S. Virgin Islands. Several locations recorded their wettest July on record, including Gainesville, FL (16.65 inches, or 423 mm), Asheville, NC (13.69 inches, or 348 mm), Greenville-Spartanburg, SC (14.45 inches, or 367 mm), Roanoke, VA (12.73 inches, or 323 mm), and San Juan, PR (14.18 inches, or 360 mm). Monthly totals at these locations also ranked in the top 5 all-time wettest months on record. Asheville, NC came within just 0.07 inches (1.8 mm) of breaking its all-time monthly total, which was last set in August 1940. Many of the highest daily rainfall totals (greater than 5 inches, or 127 mm) were recorded during the first week of the month, as a plume of deep tropical moisture spread across much of the region. In particular, over 10 inches (254 mm) of rain fell from the 4th to the 5th of the month across portions of northwest Florida, which resulted in numerous reports of flash flooding. Some locations also recorded particularly intense rainfall. On the 10th of the month, 3.37 inches (86 mm) fell in just one hour in Roanoke, VA, yielding an average return interval of 200 to 500 years. On the 9th of the month, the spillway at Lake Hartwell, one of the largest lakes in the Southeast and located along the northern border of Georgia and South Carolina, was opened for only the third time since 1948 to control for flooding. Over the past three months, rainfall totals around and upstream of the lake have exceeded 40 inches (1016 mm), which is more than 200 percent of normal. Heavy rains across South Florida also forced the release of water from Lake Okeechobee to help mitigate flooding from a potential tropical cyclone. The heavy rains across western North Carolina caused several cracks along part of the Blue Ridge Parkway, forcing officials to close a 20 mile (32 km) section near Asheville. On the 18th of the month, a strong tropical wave dropped 9.23 inches (234.4 mm) of rainfall in San Juan, PR, marking the second highest daily total for any month since 1898. More heavy rain towards the end of the month caused several rivers in western North Carolina to crest above flood stage, including the south fork of the Catawba River west of Charlotte, which crested at 17.31 feet (5.3 m) on the 28th, its third greatest height recorded in over 70 years. Severe flood damage to homes and buildings, as well as several washed-out sections of roadways, have resulted in numerous disasters declarations across the region. At least two drowning deaths have been confirmed across the Southeast, both occurring on the 27th in Wilson Creek in Caldwell County, NC. While most of the region observed above average rainfall for the month, parts of eastern North Carolina were relatively dry in July. Cape Hatteras, NC recorded just 1.88 inches (48 mm) for the month, which was more than 3 inches (76 mm) below normal. There were 486 preliminary reports of severe weather across the Southeast in July, with at least one report on every day of the month. The vast majority of these reports were for damaging thunderstorm winds. Winds in excess of 50 mph (22 meters per second) were also reported across Puerto Rico in association with Tropical Storm Chantal on the 9th and 10th of the month, resulting in some minor damage and heavy surf. There were also at least nine tornadoes reported or confirmed across the region. On the 2nd of the month, an EF-0 tornado caused significant damage to trees and homes near the town of Roxboro in Person County, NC. A brief tornado blew roofing tiles off of several buildings near Seminole in Okaloosa County, FL on the 5th, while a waterspout that moved onshore near Oldsmar in Pinellas County, FL caused minor damage to a few homes on the 8th of the month. Another brief tornado damaged several mobile homes in Palmetto in Manatee County, FL on the 9th of the month. A waterspout was observed moving onshore on Hunting Island in Beaufort County, SC on the 13th of the month, though no damage was reported. Another waterspout on the 19th of the month came onshore near Pompano Beach in Broward County, FL. Three injuries were reported from felled tents that were set up for a lifeguard competition. On the 21st, a weak tornado was confirmed in St. John's County, FL. Two days later, another weak tornado was confirmed near Fort Lauderdale in Broward County, FL. Several boats in a local marina were overturned. Lastly, a tornado was reported near the Suwannee River State Park in Hamilton County, FL on the 31st of the month. In addition, at least four people were injured from lightning strikes during the month across Florida.July marked the first time in over three years that the Southeast region was free of any U.S. Drought Monitor designation. However, the persistent wet pattern continued to cause problems for farmers. Heavy rains and standing water prevented many farmers from harvesting their crop, cutting hay, spraying chemicals and applying treatments, and preparing fields for fall and winter crops. Mold and other fungal diseases were reported across the region, particularly on crops such as corn, tomatoes, peanuts, and forage. The excess moisture has also degraded the quality and flavor of many crops, including watermelons, tobacco, and peaches, and has hampered the growth of cotton and corn by limiting the amount of oxygen available to the roots. In some locations across northern Florida and southern Georgia, the corn crop reached only half its normal height. Agricultural officials have predicted that losses across much of the region could be in the billions of dollars. The cool, cloudy conditions have resulted in generally good air quality across most metropolitan areas in the region this summer. Through the end of July, Atlanta, GA has recorded just one air quality violation, a code red violation on the 30th of the month. This marked the latest calendar day the city has gone before its first air quality violation since 1997. For more information, please go to the Southeast Regional Climate Center Home Page.High Plains Region: (Information provided by the High Plains Regional Climate Center)Average temperatures were generally below normal in the east and above normal in the west across the High Plains Region this month. Temperature departures of 2.0-4.0 degrees F (1.1-2.2 degrees C) below normal occurred in eastern Kansas, central South Dakota, western North Dakota, and a few pockets of Nebraska. Meanwhile, western portions of Colorado and Wyoming had temperature departures of 3.0-5.0 degrees F (1.7-2.8 degrees C) above normal. The cooler temperatures in the east were in stark contrast to last year, when a good portion of the area had temperature departures of 6.0-8.0 degrees F (3.3-4.4 degrees C) above normal. Although monthly records were not set, a few stations did manage to sneak in to the top 10 rankings for warmest or coolest July. On the cool side, long-term station Wamego 4 W, which is located in northeastern Kansas, had its 5th coolest July with an average temperature of 75.6 degrees F (24.2 degrees C). The coolest July at Wamego 4 W was 72.0 degrees F (22.2 degrees C) in 1950 (period of record 1912-2013). On the warm side, Lander, Wyoming had its 10th warmest July with 74.2 degrees F (23.4 degrees C). Interestingly, 7 of the top 10 warmest Julys have occurred since 2000 in Lander and the top spot of 75.9 degrees F (24.4 degrees C) occurred in both 2003 and 2006 (period of record 1891-2013). While monthly extremes were not common, numerous daily records occurred throughout the month. One notable record was for the July all-time coolest maximum temperature in Concordia, Kansas. On July 28th, Concordia's high temperature only reached 62.0 degrees F (16.7 degrees C) and beat out the old record of 63.0 degrees F (17.2 degrees C) which occurred back in 1979 and 1988 (period of record 1885-2013). July precipitation was hit or miss across the High Plains Region. Areas receiving at least 150 percent of normal precipitation included central Kansas, central South Dakota, central and western Colorado, and scattered pockets in eastern Wyoming, north central Nebraska, southwestern South Dakota, and northern North Dakota. While rain was needed to help alleviate ongoing drought conditions, some storms brought heavy rain which caused mudslides in fire burn scars in Colorado and flash flooding in parts of Colorado, Kansas, and Wyoming. Areas which missed out included eastern and central Nebraska, eastern and central North Dakota, and central Wyoming. These areas received less than 50 percent of normal precipitation. Because of the wide range in precipitation, there were stations which ranked in the top 10 driest or wettest Julys on record. With only 11 percent of normal precipitation, Omaha, Nebraska had its 2nd driest July on record with 0.44 inches (11 mm) of precipitation (period of record 1871-2013). The driest on record occurred only last year with 0.01 inches (0 mm). Meanwhile, precipitation in central Kansas helped alleviate drought conditions there, although long-term deficits were still high. For instance, Wichita, Kansas had measurable precipitation on 17 days in July, which broke the old record of 16 in 1950 (period of record 1888-2013). On average, Wichita has about 8 days with measurable precipitation in July. By the end of the month, Wichita received 7.69 inches (195 mm) of precipitation making this July its 4th wettest. Although 232 percent of normal, this was not nearly enough to beat the top spot of 13.37 inches (340 mm) in 1950. The latest U.S. Drought Monitor showed both improvements and degradations over the past month. At the end of July, approximately 64 percent of the Region was in moderate (D1) to exceptional (D4) drought - down just slightly from 67 percent at the end of June. An expansion of abnormally dry conditions (D0) occurred in east-central North Dakota and eastern parts of Kansas, Nebraska, and South Dakota. In addition, two new areas of D1 were introduced in far southeastern South Dakota and northeastern Kansas. One category improvements were made in some areas of north-central and eastern Colorado. There was quite a bit of jostling of drought conditions in Kansas where some areas had improvements, while others had degradations. By the end of the month, 25 percent of the state remained in the D4 designation, however. Wyoming had an increase in severe (D2) and extreme (D3) drought coverage, going from about 47 percent of the state to 52 percent of the state. According to the U.S. Seasonal Drought Outlook released July 18th, the only area of drought expected to improve was in southwestern Colorado. Drought conditions were expected to develop in north-central Colorado and persist elsewhere through October 2013.For more information, please go to the High Plains Regional Climate Center Home Page.Southern Region: (Information provided by the Southern Regional Climate Center)For the Southern Region, the month of July proved to be a cooler than normal month across the board. Temperatures across the six states generally averaged between 0 to 4 degrees F (0 to 2.22 degrees C) below normal, with the highest negative anomalies occurring in northwestern Arkansas and western Tennessee. With the exception of some areas in southern Texas, temperatures were consistently lower than normal over the course of the month. The state average temperatures for the month are as follows: Arkansas with 77.80 degrees F (25.44 degrees C), Louisiana with 80.60 degrees F (27.00 degrees C), Mississippi with 78.60 degrees F (25.89 degrees C), Oklahoma with 79.70 degrees F (26.50 degrees C), Tennessee with 75.00 degrees F (23.89 degrees C), and Texas with 81.30 degrees F (27.39 degrees C). All six states reported temperature averages that were below the 1895-2013 average. For Mississippi, it was the seventh coldest July on record (1895-2013), while Arkansas and Tennessee saw their tenth coldest July on record (1895-2013). Louisiana experienced its sixteenth coldest July on record (1895-2013), while Texas recorded its twenty-sixth coldest July on record (1895-2013). In the case of Oklahoma, it was their thirtieth coldest July on record (1895-2013). For some parts of the Southern Region, July was a much wetter than normal month, while other areas in the region experienced a much drier than normal month. The drier than normal areas of the region extended over much of the Texas and Louisiana gulf coast zones, and through eastern Arkansas and northern Mississippi. The wettest areas of the region included much of central Tennessee, central Texas, and Oklahoma, where precipitation totals ranged from one and a half to over three times the monthly normal. The state average precipitation totals are as follows: Arkansas with 4.34 inches (110.24 mm), Louisiana with 4.38 inches (111.25 mm), Mississippi with 4.35 inches (110.49 mm), Oklahoma with 5.41 inches (137.41 mm), Tennessee with 7.16 inches (181.86 mm), and Texas with 3.36 inches (85.34 mm). Tennessee experienced its sixth wettest July on record (1895-2013), while for Oklahoma, it was the tenth wettest July on record (1895-2013). Texas reported its twenty-fifth wettest July on record (1895-2013), where as Louisiana experienced its twenty-ninth driest July on record (1895-2013). All other state rankings fell within the two middle quartiles. Drought conditions changed little over the month of July. Dryness throughout much of Arkansas led to the introduction of some moderate drought. This was also the case for some parishes in west central Louisiana. Drought conditions in Texas and western Oklahoma are relatively unchanged, despite anomalously high precipitation in central Texas. In Texas, the cooler and wetter weather has helped farmers and ranchers across the state. East Texas vineyard owners are predicting one of their best harvests in years due to perfect conditions. Corn and cotton farmers in central Texas believe the July rains saved several million dollars of crops after the dry June. Still, problems for ranchers persist, but efforts to help the continually hurting herd numbers are taking place, including hay planting in 197 counties across the state to provide food for cattle. Not all of the rainfall was beneficial, however. Many rainstorms brought flooding, slowing down commuters in Houston, filling up a jail in Hale County, and flooding neighborhoods in El Paso. The rains also brought lightning, which sparked several house fires and small grassfires across the state. Damages greater than $260,000 were reported in Austin, more than 5,000 people lost power in El Paso, and several lightning-caused grassfires burned hundreds of acres across much of the central portions of the state (Information provided by the Texas State Climate Office).Unfortunately, reservoirs throughout Texas continue to decline. Many regions across the state have ramped up their water restrictions, including Stage 2 restrictions in Austin and Victoria, Stage 3 in Galveston, and Stage 4 in Marlin after Dow Chemical claimed senior water rights along the Brazos River. To combat this, water reclamation projects are gaining steam in Austin, with an estimated 8.5 billion gallons of reused water possible, and a new pipeline in Dallas from Lake Palestine, costing an estimated $2.3 billion (Information provided by the Texas State Climate Office).For more information, please go to the Southern Regional Climate Center Home Page.Western Region: (Information provided by the Western Regional Climate Center)The North American Monsoon was very active this month, bringing much needed precipitation to the Southwest. As is typical for July, dry conditions dominated in the Pacific Northwest. The Great Basin and Intermountain West saw record high July temperatures, while temperatures in coastal regions were moderated by persistent marine stratus and temperatures in the Southwest curbed by frequent thunderstorms.Persistent ridging produced record monthly temperatures in the northern Great Basin. In Nevada, Reno and Elko logged their warmest month in their 126-year records, at 80.2 F (26.8 C) and 76.8 F (24.9 C), respectively. In Utah, Salt Lake City averaged 84.1 F (28.9 C), its warmest month in a 140-year record. Boise, Idaho saw its 3rd warmest July in a 136-year record, with 30 days reaching 90 F (32.2 C), tying 2007 for the most such days in July there. In Oregon, Medford saw its hottest month in an 86-year record, averaging 78.9 F (26.1 C), surpassing the previous record of July 2009 by 1.0 F (0.6 C). In Washington, Yakima recorded its hottest month on record as well, at an average 77.5 F (25.3 C), exceeding the July 1998 record by 1.4 F (0.8 C). In the Southwest, Tucson, Arizona ended a 39-day streak (June 1-July 10) of temperature reaching 100 F (37.8 C), the longest such streak in a 119-year record. Monsoon clouds lowered temperatures from the warmest Tucson June on record to the 19th warmest July.Monsoon precipitation brought spotty and minor drought relief to Arizona and New Mexico, with many locations recording above normal precipitation. After consecutive below normal monsoon seasons, the Albuquerque, New Mexico airport recorded 2.77 in (70 mm) this month, the 9th wettest July in a 117-year record. This rainfall came in deluges, with nearly half (1.36 in/35mm) on the 26th, resulting in some flooding. In Arizona, Flagstaff tied 1919 for the wettest July on record at 7.58 in (193 mm). Phoenix, Yuma, and Tucson all saw an excellent start to the monsoon season as well, receiving above normal precipitation for the month. Cedar City, Utah logged 5.25 in (133 mm) of monsoon rain, 625% of normal and easily surpassing the previous July record of 4.37 in (111 mm) set in 1975. Los Angeles, California typically receives no precipitation in July, so that a mere 0.09 in (2.3 mm) led to the 3rd wettest July in a 108-year record. In contrast, the Northwest experienced its typical dry July weather. Seattle, Washington received a trace of precipitation this month, tying 1958 and 1960 for driest July. Normal there is 0.7 in (18 mm). Quillayute, Washington averages 1.98 in (50 mm) for July, but saw only 0.01 in (0.25 mm) on the last day of the month, beating out 2010 (0.35 in/9 mm) for driest July in its 48-year record. Locations throughout Northern California, such as San Francisco and Sacramento stayed dry this month. July 6 brought the first rainfall to Las Vegas since April 16. This 80-day dry stretch is the 4th longest on record.Quiescent conditions prevailed in Hawaii for most of July until the remnants of Tropical Storm Flossie brought high winds and locally heavy precipitation near the close of the month. Storm totals were highest around Maui County, helping stations in that area surpass their July normals. Kahului recorded 0.86 in (22 mm) for the month, 238% of normal. Of this, 0.79 in (20 mm) fell on the 29th associated with Flossie. Further north, warm temperatures continued in Alaska this month. Anchorage set a record of 14 consecutive days above 70 F (21.1 C) July 17th-30th. This beats the previous record of 13 days set in August of 2004 and helped to make this the 4th warmest July on record in Anchorage. On July 31, Fairbanks tied its all-time record for number of 80 F or greater (26.7 C) days in a summer at 30 days. So far, this is the second warmest summer on record at Fairbanks behind the summer of 2004. July (all month): Wildfires in the West: Though many large fires burned throughout the West this month, year-to-date the nationwide number of fires is 58% of the 10-year normal and acres burned is 55% of the 10-year normal. Some of the fires include:Douglas Complex Fire, Southwest Oregon: This group of fires ignited by lightning on the 26th had burned approximately 28,000 acres (11,300 hectares) and was 9% contained at month's end. Smoke from these fires has produced hazardous air quality in many southwest Oregon cities such as Medford, Grants Pass and Glendale. Bison Fire, Northwest Nevada: This lightning-caused fire burned from July 4th through July 14th, charring over 24,000 acres (9,700 hectares), one of the largest fires in western Nevada history. High winds helped the fire spread quickly, and smoke from the fire caused poor air quality in Carson City and Reno, Nevada.Aspen Fire, Southeast California: This lightning-caused fire began July 22 and was 45 % contained on July 31. The fire had burned nearly 18,000 acres (7,300 hectares) and caused hazardous air quality in Mammoth Lakes and northern Inyo County. July (throughout month): Flooding in the Southwest: Heavy precipitation caused several instances of flooding in Arizona and New Mexico. On July 28, a tour bus was swept off the road while trying to cross a wash near Kingman, Arizona. In Albuquerque, high winds and lightning caused power outages. Flooding and winds damaged homes and businesses as well as city's zoo. For more information, please go to the Western Regional Climate Center Home Page.
