TAMPA, Fla. (AP) — A tropical storm warning for Isaac has been extended farther up Florida's west coast, north of the Tampa Bay area.
The wider warning comes soon before the Republican National Convention was scheduled to begin Monday. Most of the schedule has now been put off until Tuesday.
At 11 p.m. EDT on Saturday, the center of the storm was located about 340 miles (547 kilometers) east-southeast of Key West, Fla.
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.
