HAZARDS AFFECTING LAND ---------------------- Key Messages for Milton can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml 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... Anna Maria Island, FL to Boca Grande, FL...10-15 ft Anclote River, FL to Anna Maria Island, FL...8-12 ft Tampa Bay...8-12 ft Boca Grande, FL to Bonita Beach, FL...8-12 ft Charlotte Harbor...8-12 ft Bonita Beach, FL to Chokoloskee, FL...5-8 ft Aripeka, FL to Anclote River, FL...4-7 ft Chokoloskee, FL to Flamingo, FL...3-5 ft Sebastian Inlet, FL to Altamaha Sound, GA...3-5 ft Altamaha Sound, GA to Edisto Beach, SC...2-4 ft Yankeetown, FL to Aripeka, FL...2-4 ft Dry Tortugas...2-4 ft St. Johns River...2-4 ft The deepest water will occur along the immediate coast near and to the south of the landfall location, where the surge will be accompanied by large and dangerous 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.
