On this Tuesday night, a strong tropical wave is located about 200 miles east of Barbados. It’s producing winds to near tropical storm force, and the associated thunderstorm activity continues to show signs of organization.
Conditions are expected to be favorable for development, and a tropical depression or tropical storm is likely to form tonight or Wednesday.
The 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.
An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system again on Wednesday morning.
Regardless of whether the system is a tropical wave or a 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.
