National Situation Update: Wednesday, August 16, 2006

Homeland Security Threat Level: YELLOW (ELEVATED).

Significant National Weather

Northeast: Except for a stray shower or thundershower in the Tidewater of Virginia on Wednesday, fine late-summer weather will prevail in the Northeast.

South:  Scattered showers and thunderstorms are forecast for much of the Southeast on Wednesday as a weak cold front pushes into the area and stalls. A few storms could turn severe with damaging wind gusts. Farther west, a few showers and storms move into far western Texas and isolated storms to parts of Oklahoma. Meanwhile, temperatures in the 100s will continue in much of Oklahoma and the eastern half of Texas.

Midwest: Scattered to isolated showers and thunderstorms are predicted for the Plains. While there may be some spotty heavy downpours, no excessive rainfall is expected.

West: Scattered to isolated showers and storms are forecasted for the Northwest, Rockies and higher terrain of the Southwest on Wednesday, with the heaviest downpours localized unloading on New Mexico. More flash flooding could result from these downpours. Since it is impossible to pinpoint where any such flooding will occur, residents should pay close attention to rapidly changing conditions. Sunshine will dominate the Great Basin and California. (NWS, Media Sources)

Tropical Activity

Atlantic/Gulf of Mexico/Caribbean Sea:  Slow formation of a tropical depression several hundred miles southeast of the Carolinas is possible during the next couple of days. While a broad area of circulation does exist, convection has been minimal. More showers and thunderstorms will need to flare up around this system before it garners more interest. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system today, if necessary.

A large cluster of showers and thunderstorms developed in the northern Gulf of Mexico Tuesday and raised concerns about the potential for tropical development. This convection has trended towards weakening, however, some slow development of this system is possible over the next day or so

Elsewhere, tropical storm formation is not expected through Thursday, August 17th.

Eastern Pacific:  The National Hurricane Center has begun issuing advisories on newly-formed Tropical Depression 9-E, a cluster of showers and thunderstorms centered approximately 750 miles SSW of the southern tip of Baja California. Initial intensity is set at 34.5 mph. The forecast calls for this cyclone to intensify over the next several days (its name would be Gilma), it is expected to continue to move westward, away from land.

Elsewhere, tropical storm formation is not expected through Thursday.

Western Pacific: Tropical Storm Wukong (50 mph) is swirling northwestward toward southern Japan. Wukong is expected to be approaching the southern island, Kyushu, as a minimal typhoon later this week. Meanwhile, Sonamu has weakened to a Tropical Depression and is expected to dissipate within 24 hours.  No U.S. interests will be affected.

Elsewhere, no tropical cyclones are expected through Wednesday. (USDOC/NOAA/NWS, National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center).
