WIND: Tropical storm conditions will continue along the Gulf coast
of Florida in the warning area today. Tropical storm conditions are

by late today or tonight and along the South Carolina coast tonight
and early Thursday. Tropical storm conditions are possible in the
watch area in the mid-Atlantic and northeastern states by Thursday

STORM SURGE: The combination of a 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...
Suwannee River to Aucilla River...2 to 4 ft
Middle of Longboat Key, FL to Suwannee River including Tampa Bay...1
to 3 ft
Aucilla River to Ochlockonee River...1 to 3 ft
Mouth of St. Marys River to South Santee River...1 to 2 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.
