HAZARDS AFFECTING LAND
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Shell Beach to Dauphin Island, Alabama...3 to 5 ft.
Navarre Florida to Dauphin Island, including Mobile Bay...2 to 4 ft.
Shell Beach to the Mouth of Mississippi River...2 to 4 ft.
Mouth of the Mississippi River to the Louisiana-Texas border...1 to
The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your area,
please see products issued by your local National Weather Service
RAINFALL: Gordon is expected to produce total rain accumulations of
2 to 4 inches over the northwestern Bahamas, Florida Keys, and South
Florida through early Tuesday. Isolated maximum amounts of 8 inches
are possible over the southern Florida peninsula.
Gordon is expected to produce total rain accumulations of 4 to 6
inches over southern Alabama, southern and central Mississippi, and
southeastern and northeastern Louisiana, with isolated maximum
amounts of 8 inches through late Thursday.

storm conditions are expected within portions of the central Gulf
Coast warning area by late Tuesday, with hurricane conditions
