HAVANA - Forecasters say Tropical Storm Isaac has entered the Florida Straits after passing over Cuba and is expected to strengthen.

At 11 p.m. EDT on Saturday, the center of the storm was located about 65 miles (105 kilometers) northeast of Camaguey, Cuba.

It was moving northwest at 17 miles per hour (27 kph) with maximum sustained winds of 60 mph (97 kph).

A tropical storm warning for Haiti, where Isaac killed at least four people, was canceled.

A tropical storm warning was issued farther up Florida's Gulf coast, including the Tampa Bay region where the Republican National Convention begins next week.
