As Isaac moves into warm water, threat shifts to northern Gulf

Heavy rain and strong wind from Tropical Storm Isaac pounded parts of south Florida on Sunday, but the threat to the state lessened as forecasters said the storm would move west of its originally predicted path. Isaac, which should strengthen into a hurricane in the next day or two, is expected now to strike further west, anywhere between Florida and Louisiana. The entire area from east of Morgan City, Louisiana, to Destin on the Florida Panhandle was under a hurricane warning. It appeared the storm would mostly bypass Florida’s west coast and the Republican National Convention in Tampa, where the schedule was pushed back a day by organizers.
