HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Depression Four can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC and on the web at www.hurricanes.gov/graphics_at4.shtml?key_messages. WIND: Tropical storm conditions are expected to first reach the coast within the warning area by late this afternoon, making outside preparations difficult or dangerous. RAINFALL: The depression 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 Alabama. 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.
