Beach Hazards Statement issued June 20 at 9:55PM PDT until June 24 at 5:00PM PDT by NWS San Francisco CA
* WHAT...An increased risk of sneaker waves and strong rip currents expected. * WHERE...Pacific Coast beaches. * WHEN...Through Wednesday afternoon. * IMPACTS...Dangerous swimming and surfing conditions and localized beach erosion can be expected. Sneaker waves can sweep across the shoreline without warning, pulling people into the sea from rocks, jetties and beaches.
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.
