Beach Hazards Statement issued May 15 at 4:43AM PDT until May 18 at 9:00AM PDT by NWS San Francisco CA

* WHAT...Strong northerly winds will generate very rough conditions at area beaches along with strong rip and long shore currents. * WHERE...Greatest impacts will be along west facing beaches of the Pacific coastline. * WHEN...From Friday afternoon through Monday morning. * IMPACTS...Dangerous wind and wave conditions will impact beaches and water activities such as swimming, surfing, boating, and tide pooling. Rough seas can sweep up the beach and over rocks and jetties, pulling people into a cold turbulent ocean. Rip currents will be stronger than normal and long shore currents can move people and items in the water quickly away from the point of entry. Local beach and cliff erosion is possible. Water temperatures will also cool rapidly due to strong upwelling conditions during this time. Large tidal swings can cutoff access to beach walkers.

Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. Monitor local weather, surf, and tide forecasts at www.weather.gov/mtr.
