Hurricane Georges on the Gulf Coast in 1998 is probably best-remembered as a big rainstorm. It made landfall on September 28, 1998 near Biloxi Mississippi, as a category 2 hurricane. It slowed down, lost wind speed, and meandered across the Mississippi Gulf Coast before slowly moving eastward toward the Florida Panhandle. The slow movement resulted in flooding from heavy steady rain. Rainfall ranged from 15 to 30 inches over several days, with highest rainfall amounts measured at over 3 feet. See rainfall totals and maps from the National Weather Service.
From the National Hurricane Center report… Storm surge estimates along the Gulf Coast ranged from 5 to 9 feet in Louisiana and
Mississippi (maximum of 8.9 feet at Biloxi, MS) to 5 to 12 feet in Alabama (5 to 10 feet in Mobile County and 7 to 12 feet in Baldwin County). The two highest values were 9.3 feet which occurred in west Mobile Bay, and 11.9 feet in Fort Morgan. In the Florida
Panhandle, the storm surge in Escambia, Santa Rosa, and Okaloosa Counties was estimated to be 5 to 10 feet. Breaking waves superimposed on the storm surge created higher water levels.
More than two dozen tornadoes were spawned by Georges, and most of those happened in the Florida Panhandle. Here is the full summary report on Hurricane Georges from the National Hurricane Center. See some before and after photos of the coastline from the USGS.
