MIAMI -- A hurricane hunter aircraft is headed toward a tropical depression that forecasters say likely will become Tropical Storm Isaac and that organizers for the Republican National Convention being held in Tampa next week are watching.
Storm warnings have been issued Tuesday across a swath of islands in the Caribbean.

It is too soon to say what exact path the storm will take. But some computer models show it headed toward Cuba and then Florida. Others have it making a sharp northern turn in the next couple days near Puerto Rico and then into the open Atlantic.
The depression has maximum sustained winds near 35 mph but is expected to strengthen.
The depression is about 550 miles east of Guadeloupe and is moving west near 18 mph.
