NOAA: Contiguous U.S. Experiences Third-Hottest Summer on Record

Warm and dry conditions continue in August; Isaac brings heavy rain to Gulf Coast and some drought relief to the Midwest

The average temperature for the contiguous U.S. during August was 74.4°F, 1.6°F above the long term average, marking the 16th warmest August on record. The warmer than average August, in combination with the hottest July and a warmer than average June, contributed to the third hottest summer on record since recordkeeping began in 1895.

The summer season's (June-August) nationally-averaged temperature was 74.4°F, 2.3°F above the 20th century average. Only the summers of 2011 (74.5°F) and 1936 (74.6°F) had higher temperatures for the Lower 48.

The August nationally-averaged precipitation total of 2.59 inches was near the long-term average. The Southwest and Southeast were wetter than average and the Northwest and the Northern Plains were drier than average. As of August 28th, according to the U.S. Drought Monitor, nearly 63% of the contiguous U.S. continued to experience drought conditions. 

August climate highlights:

  • Higher-than-average temperatures occurred across much of the West. Much of the Northeast was also warmer than average, where five states from Maine to Delaware had monthly temperatures among its ten warmest.
  • Drier-than-average conditions stretched from the Pacific Northwest, through the Rockies, and into the Upper Midwest. 
  • Hurricane Isaac made landfall along Louisiana's coast on August 28th with maximum sustained winds of 80 mph. The major impacts from the hurricane were storm surge along the Gulf Coast and heavy rainfall, both of which were driven partially by the storm's slow motion and large size.
  • Over 3.6 million acres burned nationwide, mostly across the West. The acreage burned was nearly twice the August average and the most for the month in the 12-year period record.

A Year of Extreme Weather

Guest blog post by Assistant Administrator for Weather Services and Director of the National Weather Service Dr. Jack Hayes

As the extreme weather year of 2011 comes to a close, I want to reflect back on this year’s events and look ahead at ways to reduce the devastating impacts of weather on our society.

Crippling snowstorms in the Northeast and Midwest, violent tornadoes in the South, massive river flooding in the Central U.S., Hurricane Irene in the mid-Atlantic, and the epic drought in the Southern Plains accompanied by heat waves and devastating wildfires in some areas have all combined to make this a record-breaking year.

This is the first year since NOAA began keeping records that 12 separate weather events each caused more than $1 billion in damage.   The real story is not the number of events, but the severity of the impacts. Total economic losses from these 12 events have reached nearly $52 billion, and there have been more than 1000 weather-related death this year.

Could some of these deaths have been prevented; could the economic losses be reduced?   I think so and that is why we have launched a new initiative to build a Weather-Ready Nation.  This effort is designed to improve America’s responsiveness to weather events with the ultimate goal of saving more lives and livelihoods.

Improving weather today allowed both NOAA overflights and dispersant operations to resume. Today, four aircraft applied dispersants to the surface slick, and dispersant application by vessels is expected to begin tomorrow. Monitoring of the dispersant efforts are ongoing. NOAA overflights were conducted over the source as well as south from Mobile. At present, technical specialists and other personnel from many agencies and organizations are assisting NOAA in providing scientific support for the spill response. (Incident News)

NOAA's GOES-15 Weather Satellite Captures Its First Image of Earth

GOES-15, launched on March 4 from Cape Canaveral, Florida, joins three other NOAA operational GOES spacecraft that help the agency's forecasters track life-threatening weather—from tornadoes, floods and hurricanes—and solar activity that can impact the satellite-based electronics and communications industry. The black and white full-disk image shows North and South America with a storm system visible across the United States, indicated by a drape of clouds from New England westward to the central Plains. Further west is a cold front over the Rocky Mountains. Mostly clear skies are seen over the mid-Atlantic, southeastern U.S., Gulf of Mexico, California and Mexico. (More)

50th Anniversary of the Satellite that "Forever Changed Weather Forecasting"

Fifty years ago today, the world’s first weather satellite lifted off from Cape Canaveral, Fla., and opened a new and exciting dimension in weather forecasting. Top leaders from Commerce’s NOAA and NASA hailed the milestone as an example of their agencies’ strong partnership and commitment to flying the best satellites today and beyond. The first image from the satellite, known as TIROS-1, was a fuzzy picture of thick bands and clusters of clouds over the United States. An image captured a few days later revealed a typhoon about 1,000 miles east of Australia. TIROS-1, a polar-orbiting satellite, weighed 270 pounds and carried two cameras and two video recorders.

NOAA: Imminent Flood Threat in Midwest, South and East at Risk

Major flooding has begun and is forecast to continue through spring in parts of the Midwest according to NOAA’s National Weather Service. The South and East are also more susceptible to flooding as an El Niño influenced winter left the area soggier than usual. Overall, more than a third of the contiguous United States has an above average flood risk—with the highest threat in the Dakotas, Minnesota and Iowa, including along the Red River Valley where crests could approach the record levels set just last year.

As one of the snowiest winter seasons in many years yields to warmer weather and the promise of rain and snowmelt, the Federal Emergency Management Agency’s (FEMA) FloodSmart campaign and Commerce’s National Oceanic and Atmospheric Administration (NOAA) announced they are again working together during Flood Safety Awareness Week (March 15-19) to raise awareness of the dangers associated with flooding and steps to protect against damage.

Commerce’s National Oceanic and Atmospheric Administration (NOAA) and NASA officials announced a new Geostationary Operational Environmental Satellite (GOES), launched tonight, successfully reached its initial orbit, joining four other GOES spacecraft that help NOAA forecasters track life-threatening weather and solar activity. “Our geostationary satellites are the nation’s weather sentinels in the sky,” said Jane Lubchenco, Ph.D., Under Secretary of Commerce for Oceans and Atmosphere and NOAA administrator. “With more than 35 million Americans living in hurricane prone areas and more than 1,000 tornadoes touching down in the U.S. annually, we need the reliable, accurate data that these satellites provide.” (More) (Launch image)

NOAA National Weather Service to Use New Hurricane Wind Scale

NOAA’s National Weather Service will use a new hurricane scale this season called the Saffir-Simpson Hurricane Wind Scale. The scale keeps the same wind speed ranges as the original Saffir-Simpson Scale for each of the five hurricane categories, but no longer ties specific storm surge and flooding effects to each category. Changes were made to the Saffir-Simpson Scale because storm surge values and associated flooding are dependent on a combination of the storm’s intensity, size, motion and barometric pressure, as well as the depth of the near-shore waters and local topographical features.
