Tropical Storm Isaac pushed its way into Cuba on Saturday after sweeping across Haiti's southern peninsula, where it caused flooding and at least three deaths, adding to the misery of a poor nation still trying to recover from the terrible 2010 earthquake.
Isaac's center made landfall just before midday near the far-eastern tip of Cuba, downing trees and power lines, and the storm's surge flooded the seaside Malecon in the picturesque city of Baracoa.
Forecasters said Isaac poses a threat to Florida Monday and Tuesday, just as the Republican Party gathers for its national convention in Tampa. It could eventually hit the Florida Panhandle as a Category 2 hurricane with winds of nearly 100 mph.
