    near 105.

    WHERE: The East Bay and San Francisco Bay Shoreline, North Bay
    Interior Mountains and Valleys, The Santa Clara Valley and Eastern
    Hills, The Santa Cruz Mountains, Interior Monterey County and the

    Coastal Flood Advisory - 12:33pm Wed Oct 7 2026

    ...COASTAL FLOOD ADVISORY IN EFFECT FROM 9 AM FRIDAY TO 3 PM PDT TUESDAY...

    WHAT: Up to 1.2 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 Monterey
    Bays.

    WHEN: From 9 AM Friday to 3 PM PDT Tuesday.

    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.

    ADDITIONAL DETAILS: At the San Francisco tidal gauge, high tide
    is expected to be 1.0 ft above normal (6.86 ft MLLW) at 11:22
    AM Friday 10/9, 1.2 ft above normal (7.06 ft MLLW) at 11:50 AM
    Saturday 10/10, 1.2 ft above normal (7.08 ft MLLW) at 12:18 PM
    Sunday 10/11, 1.2 ft above normal (7.03 ft MLLW) at 12:46 PM
    Monday 10/12, 1.1 ft above normal (6.90 ft MLLW) at 1:14 PM
    Tuesday 10/13, and 0.9 ft above normal (6.72 ft MLLW) at 1:46 PM
    Wednesday 10/14. 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.
