Tropical Storm Erika Prompts Watches For Leeward Islands; Potential Threat to Puerto Rico, Virgin Islands, Hispanola, Bahamas

Tropical Storm Erika formed late Monday night in the central Atlantic and is currently about 645 miles east of the Leeward Islands.
Tropical storm watches were posted Tuesday morning for parts of the Leeward Islands, and additional watches and or warnings may be required soon.
Erika is expected to remain a tropical storm and slowly gather strength as it moves quickly to the west.
The northern Leeward Islands may feel tropical storm-force winds by late Wednesday night into early Thursday.
Erika may then bring more rain to drought-suffering Puerto Rico and the Virgin Islands.
Erika’s future track and intensity beyond Puerto Rico and the Virgin Islands is highly uncertain, and may involve a track near the Bahamas this weekend and possibly parts of the Southeast U.S. coast next week.http://www.weather.com/storms/hurricane/news/tropical-storm-hurricane-erika-atlantic-august-2015
