* WHAT...Up to 1.5 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. * WHERE...North Bay Interior Valleys and San Francisco Bay Shoreline. * WHEN...Until 4 PM 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: 1.3 ft above normal (7.1 ft MLLW) at 12:10 PM Thursday 11/12, 1.5 ft above normal (7.3 ft MLLW) at 12:49 PM Friday 11/13. These predictions include up to 1.8 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.

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.
