For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. A Tropical Storm Warning means that tropical storm conditions are occurring within the warning area.

Western to central North Carolina and far southeast Virginia: 4 to 6 inches, isolated amounts up to 8 inches. Scattered flash flooding and widespread minor river flooding is possible. 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. 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... AL/FL Border to Walton/Bay County Line, FL including Pensacola Bay and Choctawhatchee Bay...2-4 ft Walton/Bay County Line, FL to Chassahowitzka, FL including Saint Andrew Bay...1-3 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and damaging waves. 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. WIND: Tropical storm conditions will continue in portions of the warning area tonight. TORNADOES: A few tornadoes may occur this afternoon and tonight across portions of northern Florida and southern Georgia. The threat of tornadoes will shift northeastward into parts of eastern Georgia and much of the Carolinas on Thursday.
