Minor Expected Likely

High Surf Advisory

High Surf Advisory issued December 3 at 3:33PM PST until December 4 at 12:00PM PST by NWS Los Angeles/Oxnard CA

Dec 3, 3:33 PM → Dec 4, 12:00 PM

WHAT: Large breaking waves 4 to 7 feet with dangerous rip
currents. Tidal overflow will flood some normally dry beach

uncommon with normal tidal ranges. Enhanced beach erosion is
also possible. No significant damage is expected.

ADDITIONAL DETAILS: High tides of 7.2 to 7.8 feet MLLW will
occur between 6 and 10am each morning. Minor coastal flooding
will persist through Saturday due to the very large high tides.
A Beach Hazard Statement will likely to be issued following the
expiration of this High Surf Advisory.

Take the necessary actions to protect flood-prone property. Do NOT drive around barricades or through water of unknown depth. Remain out of the water due to dangerous surf conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks.
