What
For the High Rip Current Risk, dangerous rip currents. For the High Surf Advisory, large breaking waves of 4 to 6 feet in the surf zone. For the Coastal Flood Advisory, up to one foot of inundation above ground level expected along shorelines and tidal waterways (7.5 to 7.7 feet Mean Lower Low Water at Charleston). For the Coastal Flood Watch, one to two feet of inundation above ground level possible along shorelines and tidal waterways (7.9 to 8.1 feet Mean Lower Low Water at Charleston).
Impacts
Significant saltwater inundation will render numerous roads impassable. Properties may also flood. Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water.
Additional details
High tide will occur around 7:13 PM today and around 7:34 AM Sunday at Charleston. Saltwater inundation will be possible 1 to 2 hours before and after high tide.
Precautionary actions
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.
