Storm clouds roll in over as the first real impacts of Isaac reach the beaches of Gulf Shores, Ala. on Tuesday, Aug. 28, 2012. The National Hurricane Center predicted Isaac would grow to a Category 1 hurricane over the warm Gulf and possibly hit late Tuesday somewhere along a roughly 300-mile (500-kilometer) stretch from the bayous southwest of New Orleans to the Florida Panhandle.
