    Where
    Pacific Coast.

    Issued for this forecast zone · National Weather Service San Francisco CA

    What, impacts and precautions

    What

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

    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 1.7 ft above normal (7.5 ft MLLW) at 11:39 AM Monday 10/26, 1.8 ft above normal (7.6 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 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.
