Isaac Blows Past Florida Keys with Little Damage

Tropical Storm Isaac rolled over the open Gulf of Mexico on Monday, where it was expected to grow into a hurricane before hitting land somewhere between Louisiana and Florida and close to the seventh anniversary of Hurricane Katrina. The storm that left eight dead in Haiti blew past the Florida Keys with little damage and promised a drenching but little more for Tampa, where the planned Monday start of the Republican National Convention was pushed back a day in case Isaac passed closer to the bayside city.
