HAZARDS AFFECTING LAND
WIND: Hurricane conditions are possible over portions of the
Hurricane Watch area by Thursday afternoon. Tropical storm
conditions are possible over portions of the Tropical Storm Watch
area by Thursday afternoon.
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. There is a
possibility of life-threatening inundation within the next 48 hours
along the Gulf coast of Florida from Aripeka to Indian Pass. For a
depiction of areas at risk, please see the Prototype National
Weather Service Storm Surge Watch/Warning Graphic. Persons located
within these areas should be prepared to take all necessary actions
to protect life and property from rising water. Promptly follow
any instructions from local officials.
The water could reach the following heights above ground if the
peak surge occurs at the time of high tide…
Indian Pass to Aripeka…2 to 4 feet
Aripeka to Bonita Beach…1 to 2 feet

RAINFALL: The depression is expected to produce additional rain
accumulations of 3 to 5 inches over western Cuba through Wednesday,
with maximum storm total amounts up to 20 inches. These rains
could cause life-threatening flash floods and mud slides. Storm
total rainfall amounts of 5 to 10 inches are possible over much of
the Florida peninsula through Friday morning, with isolated maximum
amounts of 15 inches possible. This rainfall may cause flooding
and flash flooding.
