Tomas has strengthened back into a tropical storm as it steams toward Haiti.
A tropical storm warning and a hurricane watch have been issued for the island nation. Tropical storm watches are also in effect for parts of Cuba, the Dominican Republic, Jamaica and the Bahamas.
The center of the storm is expected to approach Haiti on Friday.
Winds have increased to near 45 mph and the National Hurricane Center says Tomas could be near hurricane strength as it gets closer. The storm had earlier been downgraded to a tropical depression.
Tomas is about 305 miles (490 km) south-southwest of Port Au Prince, Haiti, and about 250 miles (405 km) south-southeast of Kingston, Jamaica.
