Event:
Coastal Flood Advisory
Urgency:
Expected
Effective:
July 12, 2026 - 1:40pm
Expires:
July 12, 2026 - 9:45pm
Description:
* WHAT...Up to 1.7 ft of inundation above ground level is possible
in low-lying areas near shorelines and tidal waterways.
* WHERE...Bayshore locations along the San Francisco and San Pablo
Bays.
* WHEN...Until 4 AM PDT Thursday.
* IMPACTS...Flooding of lots, parks, and roads with only
isolated road closures expected.
* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide
is expected to be 1.7 ft above normal (7.5 ft MLLW) at 10:06 PM
7/12, 1.7 ft above normal (7.5 ft MLLW) at 11:01 PM 7/13, 1.6 ft
above normal (7.4 ft MLLW) at 11:55 PM 7/14, 1.3 ft above normal
(7.1 ft MLLW) at 12:48 AM 7/16. These predictions include both
astronomical tides and roughly 3-6 inches of additional water
mainly from a combination of thermal expansion and accumulated
sea level rise since the tidal datum was established (1983-
2001). 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.
