Precautionary/preparedness actions...

A high surf advisory means that high surf will affect beaches in the advisory area...producing rip currents and localized beach erosion.

Remember...if caught in a rip current...swim parallel to shore until you are free of the powerful current. Always swim near a lifeguard.

A coastal Flood Advisory indicates that the very large surf and high tides will combine to generate flooding of low lying areas along the shore.
