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...
Mouth of the Pearl River to Intracoastal City...3 to 6 ft
Surge-related flooding depends on the relative timing of the surge

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