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…

Indian Pass FL to Chassahowitzka FL…3 to 5 ft
Chassahowitzka to Clearwater Beach FL…2 to 4 ft

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 forecast office.

WIND: Tropical storm conditions are expected to first reach the coast within the warning area by Friday afternoon, making outside preparations difficult or dangerous. Gale-force winds are possible along portions of the Atlantic coast of the southeastern United States by Saturday.

RAINFALL: The disturbance is expected to produce total rainfall accumulations of 2 to 4 inches this weekend from the central Gulf Coast and northern and central Florida to the eastern Carolinas, with isolated maximum amounts of 5 inches.
