Coastal Flood Advisory issued November 9 at 12:13PM PST until November 13 at 4:00PM PST by NWS San Francisco CA

North Bay Interior Valleys; San Francisco Bay Shoreline Nov 9, 12:13 PM - Nov 9, 08:15 PM
Severity: Minor Urgency: Expected

* WHAT...Up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...Bayshore locations along the San Francisco Bay and San Pablo Bay. * WHEN...Until 4 PM PST Friday. * 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. * ADDITIONAL DETAILS...At the San Francisco tide gauge, high tide is expected to be: 1.5 ft above normal (7.3 ft MLLW) at 11:04 AM Tuesday 11/10, 1.4 ft above normal (7.2 ft MLLW) at 11:35 AM Wednesday 11/11, 1.3 ft above normal (7.1 ft MLLW) at 12:10 PM Thursday 11/12, 1.1 ft above normal (6.9 ft MLLW) at 12:49 PM Friday 11/13. These predictions include up to 1.4 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.
