Event:
Coastal Flood Advisory
Urgency:
Expected
Effective:
October 11, 2026 - 8:45pm
Expires:
October 12, 2026 - 4:45am
Description:
* WHAT...Up to 1.5 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal
waterways.
* WHERE...Bayshore locations along the San Pablo Bay.
* WHEN...Until 4 PM PDT Wednesday.
* IMPACTS...Flooding of lots, parks, and roads with only
isolated road closures expected. High tides will result in
flooding along coastal trails, cut off access to some low-
lying beaches and coastal areas, and bring water and waves
farther up the beach than typical. Dangerous conditions are
forecast along the shoreline. Hazards include sneaker waves,
strong rip currents, and large breaking waves.
* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide
is expected to be 1.5 ft above normal (7.3 ft MLLW) at 12:46 PM
Monday 10/12, 1.4 ft above normal (7.2 ft MLLW) at 1:14 PM Tuesday
10/13, and 1.0 ft above normal (6.8 ft MLLW) at 1:46 PM Wednesday
10/14. These predictions include up to 1.5 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.
Instruction:
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.
