For the Beach Hazards Statement, An increased risk for sneaker waves and strong rip currents with breaking waves of 15 to 20 ft expected. For the High Surf Warning, Dangerously large breaking waves of 25 to 35 ft, with occasional sets of 40 to 50 ft at favored breakpoints. For the second Coastal Flood Advisory, large breaking waves will run up beaches and crash over seawalls, inundating adjacent, low-lying infrastructure. * WHERE...San Francisco and Southern Monterey Bay and Big Sur Coast. * WHEN...For the first Coastal Flood Advisory, until 4 PM PST today. For the Beach Hazards Statement, through this afternoon. For the High Surf Warning, from 6 PM today to 4 AM PST Sunday. For the second Coastal Flood Advisory, from midnight tonight to 6 PM PST Saturday. * 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. Dangerously large breaking waves can overpower swimmers, pulling people into the sea from beaches, jetties, and rocks resulting in significant physical injury and increasing the risk of drowning. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks. * ADDITIONAL DETAILS...At the San Francisco tide gauge, high tide is expected to be: 1.5 ft above normal (7.3 ft MLLW) at 12:49 PM today 11/13.

High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively. The Coastal Flood Advisory on Saturday is specifically for the Pacific Coast, where large breaking waves will spill over sea walls and run up beaches onto adjacent infrastructure. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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. Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure. 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. &&
