Tropical Storm Tammy is expected to be a hurricane or at near-hurricane strength while moving close to the islands in the far eastern Caribbean this weekend, according to the latest forecast.
Tammy is centered 185 miles east of Martinique in the Lesser Antilles and is moving west-northwest.
Tammy should begin to turn more northward with time, putting it on a track that will pass near the northeast Caribbean islands by later Friday and Saturday. Thereafter, Tammy should turn northeastward out to sea and not be a concern for the continental United States.
Tammy is forecast to be a strong tropical storm or a Category 1 hurricane when it tracks near the eastern Caribbean islands.
The latest hurricane and tropical watches and/or warnings for the Caribbean are shown in the map below.
Rainfall, strong winds and high surf from Tammy should arrive in the eastern Caribbean islands on Friday. Those impacts will last through at least Saturday in some areas.
Rainfall totals could be 4 to 8 inches (locally up to 12 inches) in the Leeward Islands. The northern Windward Islands might see 2 to 4 inches of rain (locally up to 6 inches). Parts of eastern Puerto Rico and the Virgin Islands could see 1 to 2 inches of rainfall (locally up to 4 inches).
The heavy rainfall could cause flooding and mudslides in some of these areas.
