* WHAT...For the High Surf Advisory, large breaking waves of 1 to 5 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents. For the Coastal Flood Advisory, up to one foot of inundation above ground level expected along shorelines and tidal waterways (9.9 to 10.1 feet Mean Lower Low Water at Fort Pulaski). * WHERE...In Georgia, Coastal Bryan, Coastal Chatham, Coastal Liberty …

If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. Visit water.weather.gov for additional water level and flood impact information. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Swim near a lifeguard. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
