Key messages for Tropical Storm Danny can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44
KNHC and on the web at
WIND: Tropical storm conditions are expected to first reach the
coast within the warning area very soon making outside preparations
difficult or dangerous.
RAINFALL: Danny could produce 1 to 3 inches of rainfall with
locally higher amounts along the immediate coasts of Georgia and
southern South Carolina. This region has been dry, limiting
potential widespread flooding impacts, however, local flooding
impacts, especially in urban areas along the southern South Carolina
and Georgia coasts, cannot be ruled out at this time.
Farther inland, 1 to 2 inches of rainfall is possible across Upstate
South Carolina, the Piedmont of Georgia, and into northeastern
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...
Port Royal Sound, SC to South Santee River, SC...1 to 3 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.
TORNADOES: An isolated tornado will be possible this evening along
the South Carolina coast.
