Tropical Storm Isaac takes aim at Haiti, Dominican Republic

MIAMI - Tropical Storm Isaac headed toward the Dominican Republic and Haiti on Friday, continuing its march across the Caribbean after unleashing heavy rain on parts of Puerto Rico.
Isaac also posed a threat to Florida, where it could pass near the state's Gulf Coast on Monday as the Republican National Convention starts in Tampa.
Authorities have not ruled out the possibility of postponing or relocating the Republican convention if the storm takes direct aim at Tampa. But Craig Fugate, director of the Federal Emergency Management Agency, said the convention was not his biggest concern, at least for now.
