A strong tropical wave located East of the islands is producing winds to near tropical storm force, and the associated thunderstorm activity continues to show signs of organization.
A reconnaissance aircraft will investigate the system again this morning, and it could be upgraded to a tropical depression or tropical storm at this time.
The system is moving westward to west-northwestward at 15 to 20 mph, and is expected to pass over the Windward Islands later today, and move over the southeastern Caribbean Sea tonight and Thursday.
Conditions are expected to further deteriorate during the morning, with some pockets of moderate to heavy showers, periods of rain, thunderstorms and gusty winds.
Interests in the Windward and southern Leeward Islands, Bonaire, Curacao, Aruba, and along the northern coast of South America should monitor the progress of this disturbance, and consult products issued by your national meteorological service, which could include tropical storm warnings or watches.
