MIAMI (AP) - Tropical Storm Bertha is swirling through the eastern Caribbean, unleashing heavy rains and strong winds.
The storm's maximum sustained winds increased slightly today to 50 mph, but no significant change in strength is expected in the next two days.
Bertha was centered about 20 miles northwest of Martinique and was moving west-northwest at 24 mph.
Tropical storm warnings were issued for Dominica, Martinique, the U.S. and British Virgin Islands and Puerto Rico. A tropical storm watch is in effect for the eastern Dominican Republic, the southeastern Bahamas and the Turks and Caicos islands.
Bertha passed just north of the French Caribbean island of Martinique, where officials said they were bracing for heavy winds and dangerous swells and urged everyone to stay indoors.
