conditions are possible in the watch area in Cuba today and tonight.
STORM SURGE: The combination of 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...
Marco Island, FL to Card Sound Bridge...1-3 ft

Charlotte Harbor...1-2 ft
Florida Keys and Dry Tortugas...1-2 ft
Surge-related flooding depends on the relative timing of the surge
