Coastal Flood Advisory
Issued: 7:20 AM Oct. 28, 2026 – National Weather Service

FRIDAY...

* WHAT...Up to 1.9 ft of inundation above ground level is
possible in low-lying areas near shorelines and tidal waterways.

* WHERE...Pacific Coast.

* WHEN...Until 5 PM PDT 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.

tide is expected to be 1.9 ft above normal (7.7 ft MLLW) at
12:56 PM Wednesday 10/28, 1.7 ft above normal (7.5 ft MLLW) at

at 02:39 PM Friday 10/30. These predictions include up to 1.2
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
