REPORTS U.S. DROUGHT TO WORSEN IN SOUTHWEST AND May 17, 2007 � On the cusp of the summer season, NOAA meteorologists are anticipating major drought concerns in sections of the U.S. possibly fueling an already busy wildfire season. In today's updates of the U.S. Drought Monitor and the U.S. Seasonal Drought Outlook, NOAA scientists are indicating extreme drought to plague areas from Southern California into western Arizona as summer approaches. Meanwhile, drought conditions in the Southeast are expected to show some improvement in the coming weeks and months. (Click NOAA image for larger view of the U.S. Drought Monitor.

U.S. Seasonal Drought Outlook For other parts of the Southeast, improvement is less certain, especially with no significant relief showing up on medium-range weather forecasts. The latest monthly and seasonal rainfall forecasts show no tendency for below-normal conditions to persist past June, and historical comparisons with past spring droughts, along with summer climate patterns, suggest some reason for cautious optimism for improvement by summer’s end. Although tropical weather systems can lead to fast recovery of drought, NOAA cannot speculate at this time as to where any systems will strike in coming months, so location and timing of drought relief is uncertain. Little drought relief is expected from California into the Great Basin. "Since the long dry season is only just beginning for California, prospects for relief are distant and may have to wait for late autumn," said Douglas LeComte, NOAA Climate Prediction Center drought specialist. But, Arizona could experience some relief during the monsoon season, which begins in July. Farther north drought conditions are expected to persist in Montana, Wyoming, the western Dakotas and western Nebraska but are likely to improve in the Upper Midwest. Although drought is not predicted in Alaska, large areas have been unseasonably dry and any future warm, dry weather could lead to a serious wildfire season over the interior. Also, dryness may transition to drought in Hawaii, mainly in the leeward areas. The
Origin of Current Conditions The U.S. Drought Monitor is updated every Thursday. NOAA's next update for the U.S. Seasonal Drought Outlook will be on June 7. People in affected areas are advised to keep abreast of the latest local news and information. NOAA has a variety of information online to help keep you safe. The NOAA Climate Prediction Center, one of the NOAA National Centers for Environmental Prediction, provides the public with assessments and forecasts of short-term climate variability, emphasizing enhanced risks of weather-related extreme events. Its products and services cover time scales from a week to seasons, extending into the future as far as technically feasible, and cover the land, ocean and atmosphere extending into the stratosphere. NOAA, an agency of the U.S. Commerce Department, is celebrating 200 years of science and service to the nation. From the establishment of the Survey of the Coast in 1807 by Thomas Jefferson to the formation of the Weather Bureau and the Commission of Fish and Fisheries in the 1870s, much of America's scientific heritage is rooted in NOAA. NOAA 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.
