What
For the High Surf Advisory, large breaking waves of 4 to 6 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents.

Precautionary actions
Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth.
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.
