Tropical storm forms south of Puerto Rico

MIAMI (AP) — Tropical Storm Gabrielle has formed south of Puerto Rico, resulting in storm warnings.

Forecasters at the U.S. National Hurricane Center in Miami said late Wednesday that Gabrielle was centered about 70 miles

(113 kilometers) south of Ponce, Puerto Rico.

Maximum sustained winds were 40 mph (64 kph). It was moving to the northwest at 8 mph (13 kph).

Tropical storm warnings were issued for

Puerto Rico and parts of the Dominican Republic, from Cabo Engano to

Cabo Frances

Viejo. It was expected to bring 3 to 6 inches of rain to parts of

Puerto Rico, the U.S. Virgin Islands and eastern portions

of the Dominican Republic.

Forecasters expect the storm's center to pass between the islands on Thursday and eventually curve back to the northeast away

from the U.S. mainland. However, storm paths are difficult to predict accurately days in advance.
