Windward and southern Leeward Islands, Bonaire, Curacao, Aruba, and North Coast of South America, must watch this Tropical Wave.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Showers and thunderstorms associated with a tropical wave located about 350 miles east of Barbados continue to show signs of organization.  Buoy data indicate that the system is producing winds to near tropical storm force, and an Air Force Reserve reconnaissance aircraft is just beginning its mission to determine if the system has a closed circulation.  Environmental conditions appear to be favorable for development, and a tropical depression or tropical storm is likely to form later today or tonight.  This system is moving westward to west-northwestward at 15 to 20 mph, and is expected to pass over the Windward Islands on Wednesday morning, and move over the southeastern Caribbean Sea late Wednesday and Thursday.

Interests in the  should monitor the progress of this disturbance, and consult products issued by your national meteorological service, which could include tropical storm warnings or watches. Regardless of whether the system is a tropical wave or tropical cyclone, heavy rains and tropical-storm-force winds in squalls are expected to spread over the Windward Islands and portions of the southern Leeward Islands, beginning tonight and continuing through Wednesday.

* Formation chance through 48 hours...high...90 percent
* Formation chance through 5 days...high...90 percent
2. A large area of disorganized showers and thunderstorms over the southwestern Gulf of Mexico is associated with a trough of low pressure that is drifting westward.  Upper-level winds are not
expected to be conducive for significant development before this system moves inland over Mexico during the next day or so.

* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent

 

Must have an tight watch.

 

Afternoon today, I'll keep you posted.
