(RNN) - The tropical system formerly known as Tropical Storm Kirk became a tropical storm again Wednesday morning, packing 50 mph winds.
Forecasters with the National Hurricane Center in Miami don’t expect it to reach hurricane strength.
Kirk’s maximum-sustained winds increased to 60 mph by 2 p.m. Wednesday, but the wind speed hadn’t increased by the NHC’s 8 p.m. update.
The maximum-sustained winds had dropped to 50 mph by 11 p.m. Wednesday.
Little change in strength is expected through Thursday, the NHC said.
Wind shear in the eastern Caribbean Sea will tear into the storm after Thursday, knocking it back down to a depression over the weekend.
In the meantime, Kirk, which is about 170 miles east of Barbados, moving west rapidly at 16 mph, is threatening islands in the Lesser Antilles.
It’s expected to arrive near the island chain by Thursday afternoon, inundating parts of it with rainfall of 4 to 6 inches, possibly producing life-threatening flash floods and mudslides.
A tropical storm warning has been issued for Barbados, St. Lucia, Dominica, Martinique and Guadeloupe, while St. Vincent and the Grenadines are under a tropical storm watch.
