All interests from Louisiana to Mississippi, Alabama and the Florida Panhandle should rush preparations to completion.
If peak storm surge occurs at high tide, peak water levels above ground could reach the following depths as Isaac moves by:
- Southeast Louisiana, Miss., Ala. coasts: 6-12 feet
- South-central Louisiana: 3-6 feet
- Florida Panhandle: 3-6 feet
- Florida west coast from Apalachicola to south of Naples: 1-3 feet
Even as Isaac's center of circulation moves by, locally heavy rainbands can be expected. Another 1-3" of rain is possible in central and south Florida with locally higher amounts. Isolated storm total rainfalls of 15" are possible in central and South Florida. Rainfall amounts over 10" are likely as Isaac slows down immediately prior to, and after landfall, in southeast Louisiana, southern Alabama, Mississippi and the western Florida Panhandle. Isolated 20" amounts are possible.
