Thunderstorms associated with the area of low pressure located about 100 miles east-northeast of Barbados continue to show signs of organization.
However, recent satellite wind data indicates that the system currently lacks a well-defined center.
Environmental conditions are expected to remain conducive for additional development, and a tropical depression is likely to form later today or tonight while the low moves west-north-westward at 10 to 15 mph.
The disturbance is forecast to move through portions of the Lesser Antilles tonight, then move near the Virgin Islands and Puerto Rico on Tuesday, and Hispaniola on Wednesday.
Tropical storm watches or warnings could be required this afternoon with shorter-than-normal lead times for portions of the Lesser Antilles, the Virgin Islands, and Puerto Rico.
In addition, heavy rains and flooding are likely for the Leeward Islands, Virgin Islands, and Puerto Rico. Interests in those areas should monitor the progress of this system.
In the meantime, Showers and thunderstorms in association with an elongated low-pressure area located several hundred miles east of the Lesser Antilles have diminished. Environmental conditions have become unfavorable and development of this system is no longer expected.
