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 late Friday, making outside
preparations difficult or dangerous.

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.
