Tropical Storm Tammy has formed in the Atlantic. Here’s what forecasters say.

Tropical Storm Tammy — the 20th named storm of the Atlantic Hurricane Season — formed Wednesday.

Here’s what forecasters with the National Hurricane Center say:

The system, which meteorologists have been watching for a week, achieved tropical-storm force winds east of the Windward Islands.

Tropical storm watches have been issued for some of the Lesser Antilles as the storm moved west at a relatively fast 23 mph Wednesday afternoon. Forecasters say the storm likely will continue to move west through Thursday afternoon, but its pace should slow. Tropical storm conditions — strong winds and heavy rain — are possible across portions of the Lesser Antilles beginning on Friday, spreading into the British and U.S. Virgin Islands and Puerto Rico over the weekend.

Tropical storm watches are in effect for Barbados, Dominica, Martinique and Guadeloupe, and more watches or warnings will likely be issued by Thursday.

On Sunday, the storm is expected to begin to turn toward the northeast and continue on that track Monday, taking it away from the U.S. before getting close enough to have an effect on the East Coast, including North Carolina.

Tropical Storm Tammy formed Wednesday in the Atlantic, the 20th named storm of the season. The storm is expected to bring heavy rain and high winds to islands in the Caribbean into the weekend before turning to the north-northeast by Sunday.  It’s not expected to affect North Carolina or the rest of the Southeast coast.
