A tropical storm watch remains in effect for St Lucia as a quickly moving tropical storm Don speeds toward the Windward Islands.
At 5 a.m. Tuesday, the centre of the system was about 318 miles east-southeast of St Lucia, according to the St Lucia Met Service.
Don is moving toward the west near 18 mph.
This general motion, with an increase in forward speed, is expected through Wednesday evening, forecasters say.
The tropical storm has maximum sustained winds of 50 mph with some higher gusts. Tropical-storm-force winds extend outward up to 35 miles from the centre.
The National Hurricane Centre in Miami says some strengthening is possible through tonight while Don approaches the Windward Islands.
Weakening is expected on Wednesday while Don moves across the south-eastern Caribbean Sea.
Don is expected to produce total rain accumulations of 3 to 6 inches across Barbados and the southern Windward Islands through Wednesday morning.
Experts warn that these rains could produce life-threatening flash floods and mudslides.
