3 killed As Isaac Drenches Haiti [VIDEO]

At least three deaths are being reported in Haiti, after Tropical Storm Isaac blew through. The
storm swept across Haiti's southern peninsula early today, dumping heavy rain.

Rocks, mud and other debris litter the streets of Port-au-Prince this morning and the city is on high alert for potential flooding.

But the worst of the storm has hit far from the capital. The center of Isaac passed over the southern peninsula near the small city of Les Cayes and headed toward southern Cuba.

The storm is now heading toward eastern Cuba, and forecasters say it could threaten Florida Monday and Tuesday, just as the Republican Party gathers for its national convention in Tampa.
