    Coastal Flood Advisory - 11:04am Mon Oct 26 2026

    ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 3 PM PDT THURSDAY...

    WHAT: Up to 2.1 ft of inundation above ground level is
    possible in low-lying areas near shorelines and tidal waterways.

    WHERE: Pacific Coast.

    WHEN: From 9 AM Monday to 3 PM PDT Thursday.

    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 tidal gauge, high
    tide is expected to be 2.0 ft above normal (7.8 ft MLLW) at
    11:39 AM Monday 10/26, 2.1 ft above normal (7.9 ft MLLW) at
    12:15 PM Tuesday 10/27, 1.9 ft above normal (7.7 ft MLLW) at
    12:56 PM Wednesday 10/28, and 1.7 ft above normal (7.5 ft
    MLLW) at 01:43 PM Thursday 10/29. These predictions include up
    to 1.0 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.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    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.
