Details

* WHAT...For the Beach Hazards Statement, An increased risk for sneaker waves and strong rip currents. For the Coastal Flood Advisory, Up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways.
* WHERE...San Francisco County.
* WHEN...For the Beach Hazards Statement, until 8 PM PST this evening. For the Coastal Flood Advisory, from 6 AM Wednesday to 1 PM PST Monday.
* IMPACTS...High tides will result in flooding of low-lying infrastructure, isolated road closures, and coastal erosion. Rising tides will bring water and waves farther up the beach than normal, restricting escape from beaches and coastal areas. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks.
* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide is expected to be 1.0 ft above normal (6.8 ft MLLW) at 8:00 AM Wednesday 11/4, 1.3 ft above normal (7.1 ft MLLW) at 8:35 AM Thursday 11/5, 1.4 ft above normal (7.2 ft MLLW) at 9:08 AM Friday 11/6, 1.6 ft above normal (7.4 ft MLLW) at 9:38 AM Saturday 11/7, 1.6 ft above normal (7.4 ft MLLW) at 10:06 AM Sunday 11/8, 1.6 ft above normal (7.4 ft MLLW) at 10:35 AM Monday 11/9. These predictions include up to 1.2 ft of surge that will enhance the astronomical tide and flooding threat. High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively.

Instructions

If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.
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.
