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... Marco Island, FL to Card Sound Bridge...1-3 ft Middle of Longboat Key, FL to Marco Island, FL...1-2 ft Charlotte Harbor...1-2 ft Florida Keys and Dry Tortugas...1-2 ft Card Sound Bridge to North Miami Beach, FL including Biscayne Bay...1-2 ft Extreme Northwestern Bahamas: Storm surge could raise water levels by as much as 1 to 3 ft above normal tide levels.
