Tropical Storm Isaac could become hurricane

Posted: Updated:

ROSEAU, Dominica (AP) - Tropical Storm Isaac is taking aim at the Dominican Republic and Haiti and is expected to gain strength after drenching tiny islands in its whirl over the eastern entrance to the Caribbean.

No major damage has been reported, but authorities in Puerto Rico say an elderly woman died in an accident while preparing for the storm.

U.S. forecasters say Isaac is likely to approach Hispaniola, the island shared by the Dominican Republic and Haiti, as a hurricane late Thursday or early Friday after intensifying over the warm waters of the Caribbean Sea. It's predicted to move on to Cuba as a tropical storm and perhaps menace Florida as a hurricane later in the week.

Forecasters say Isaac poses a potential threat to Florida during next week's Republican National Convention in Tampa, though the storm's track is uncertain.
