1 alert in effect — most serious first.
Coastal Flood Advisory Remains In Effect Until 4 PM PST Friday
Coastal Flood Advisory issued November 7 at 8:09PM PST until November 13 at 4:00PM PST by NWS San Francisco CA
Covers North Bay Interior Valleys; San Francisco Bay Shoreline
Up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways.
Bayshore locations along the San Francisco Bay and San Pablo Bay.
Until 4 PM PST Friday.
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.
At the San Francisco tide gauge, high tide is expected to be: 1.6 ft above normal (7.4 ft MLLW) at 10:06 AM Sunday 11/8, 1.5 ft above normal (7.3 ft MLLW) at 10:35 AM Monday 11/9, 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.
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.
Beyond the Weather Service
Three hazards the Weather Service’s alerts do not carry. Fires seen by satellite are NASA FIRMS’s detections of the last 24 hours within the Fires page’s reach, each one heat seen from orbit by the VIIRS instruments on two satellites that pass over a few times a day, grouped into fires and placed by the nearest detection; steady hot spots such as refinery flares are left out. Not every detection is a wildfire, and none says where the smoke goes.
The air quality forecast is the Bay Area Air District’s for the Redwood City area, day by day with its leading pollutant, as the EPA’s AirNow gives it; an action day is the district asking for less driving and no wood burning. The UV forecast is the EPA’s peak index for ZIP code 94303, made by NOAA’s Climate Prediction Center the day before; a UV Alert is its call that the index will be unusually high for the season.
Each card says so when it has nothing to report. The Air quality and UV index gauges’ cards on the Gauges page have the detail.
