Intracoastal City to Shell Beach…3 to 6 ft
Shell Beach to Biloxi MS…3 to 5 ft
Lake Pontchartrain…3 to 5 ft
Biloxi MS to the Mississippi/Alabama border…1 to 3 ft
Lake Maurepas…1 to 3 ft

information specific to your area, please see products issued by
your local National Weather Service forecast office.
