U.S.
HAS COOLER SEPTEMBER AFTER NEAR RECORD WARM SUMMER, Oct. 16, 2006 � September 2006 was cooler than average for the continental U.S., providing relief from the second-warmest summer on record, according to scientists at the NOAA National Climatic Data Center in Asheville, N.C. September was the first cooler-than-average month for the continental U.S. since May 2005. Drought conditions also improved in some areas of the nation, with nationally averaged precipitation above average during September. The global temperature remained well above average.

Temperature Highlights The January-September 2006 combined temperature is warmest on record. The previous record warm January-September happened in 2000. The September temperature was below average in 25 states of the continental U.S., while above-average temperatures occurred in only five (Vermont, Montana, Idaho, Washington and Oregon). September
temperatures for Alaska averaged at 48.6 degrees F and were warmer than
average, 2.7 degrees F (1.5 degrees C) above the 1971-2000 mean (45.9
degrees), the 11th warmest September since statewide records began in
1918. Kentucky tied its September precipitation record with 8.02 inches of rain. A wetter-than-average summer monsoon season for much of the Southwest ended in September. Precipitation during the past few months ended drought in New Mexico and helped reduce drought severity in other parts of the region. However, below-average reservoirs and other longer term hydrological effects remained widespread. According to the U.S. Drought Monitor, 33 percent of the continental U.S. was in moderate to exceptional drought at the end of September, a decrease of 11 percent since the end of August. Severe-to-exceptional drought remained across large parts of Arizona, southern Oklahoma to south Texas, areas of the northern high Plains, the northern Rockies and northern Minnesota. Drier-than-average conditions across the Far West contributed to the continuation of a very active wildfire season for the nation. By early October, more than 9 million acres, mostly in the continental U.S., had burned since the beginning of the year, according to the National Interagency Fire Center. This exceeded the previous record for an entire year, set in 2005 when 8.7 million acres burned, much of it in Alaska. Global
Highlights In 2007 NOAA, an agency of the U.S. Commerce Department, celebrates 200 years of science and service to the nation. Starting with the establishment of the U.S. Coast and Geodetic Survey in 1807 by Thomas Jefferson much of America's scientific heritage is rooted in NOAA. The agency is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of the nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 60 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
