    Weather Alerts
    Coastal Flood Advisory - 4:23am Thu Oct 29 2026

    ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 6 PM PDT SATURDAY...

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

    WHERE: Bay Shoreline locations of San Pablo Bay, San
    Francisco Bay, and Monterey Bay.

    WHEN: Until 6 PM PDT Saturday.

    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. More substantial impacts are expected along bayshore
    Marin County where increased flooding is anticipated across
    low lying areas.

    ADDITIONAL DETAILS: At the San Francisco tidal gauge, high
    tide is expected to be 1.9 ft above normal (7.7 ft MLLW) at
    01:43 PM Thursday 10/29, 1.6 ft above normal (7.4 ft MLLW) at
    02:39 PM Friday 10/30, and 1.1 feet above normal (6.9 ft MLLW)
    at 03:44 PM on Saturday 10/31. 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.

    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.
