    Coastal Flood Advisory - 3:38am Wed Jul 15 2026

    ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 AM PDT THURSDAY...

    WHAT: Up to 1.5 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 1.5 ft above normal (7.3 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.

    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.
