Tropical Activity

Atlantic/Gulf of Mexico/Caribbean Sea:  A low pressure area, extending from just north of the northern Bahamas northeastward over the Atlantic Ocean for a few hundred miles changed little in organization Monday night.  The system could become more favorable for slow development over the next couple of days as the system remains nearly stationary or drifts northward.  An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system Tuesday, if necessary.

A well-organized tropical wave is located just east of the Cape Verde Islands.  Some slow development of this system is possible over the next day or so as it moves west- northwestward at 15 to 20 mph.
Elsewhere, tropical storm formation is not expected through Wednesday.

Eastern Pacific:  A low pressure area located about 500 miles south-southwest of Manzanillo, Mexico became a little better defined Monday night.  Additional development is possible over the next couple of days, as it moves west-northwestward at 15 mph.

Elsewhere, tropical storm formation is not expected through Tuesday.

Western Pacific: Tropical Storm (11w) Wukong and Tropical Storm (12w) Sonamu, are tracking towards the coast of Japan and continue to move away from U.S. interests. Elsewhere, no tropical cyclones are expected through Tuesday.(USDOC/NOAA/NWS, National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center)
