Isaac: Hurricane Warnings for Gulf Coast
Isaac will continue to affect southern Florida with heavy rain, gusty winds and a tornado threat as it moves through the Florida Keys and into the Gulf Sunday evening. Isaac poses a potential serious threat to portions of the northern Gulf Coast Tuesday into Wednesday. All interests from Louisiana to Mississippi, Alabama and the Florida Panhandle should watch the progress of Isaac closely and begin to make preparations. Even areas as far west as extreme southeast Texas should continue to monitor Isaac’s progress in case a farther west track materializes.

According to the National Hurricane Center, if peak storm surge occurs at high tide, peak water levels above ground could reach the following depths as Isaac moves by:
- Northern Gulf Coast within the hurricane warning area: 6-12 feet
- Remainder of Florida Panhandle and Apalachee Bay: 4-7 feet
- Fla. west coast, south of Apalachee Bay (incl. Tampa Bay): 2-4 feet
- Southeast Fla. coast, Fla. Keys: 1-3 feet
- Central, western Cuba: 1-3 feet
- Northwestern Bahamas: 1-3 feet
Even as Isaac’s center of circulation moves by, locally heavy rainbands can be expected. Total rainfall of up to 10 inches is possible across the Florida Keys and Central and South Florida. Later, as Isaac approaches the northern Gulf Coast, 5 to 10 inches of rain will eventually fall in some areas with the potential for a foot or more.
