    Weather Alerts
    Heat Advisory - 9:43am Thu Oct 1 2026

    ...HEAT ADVISORY IN EFFECT FROM 11 AM SATURDAY TO 10 PM PDT SUNDAY...

    WHAT: Temperatures in the middle 90s to near 103 expected. Mild
    lows in the upper 60s to middle 70s in the higher elevations will
    limit overnight recovery.

    WHERE: The East Bay and San Francisco Bay Shoreline, The Santa
    Clara Valley and Eastern Hills, Western Sonoma County Hills, The
    Santa Cruz Mountains, Interior Monterey County and the Santa Lucia
    Range, Most of San Benito County and the Cholame Hills in Southeast
    Monterey County, North Bay Interior Mountains, and Southern Salinas
    Valley/Arroyo Seco and Lake San Antonio.

    WHEN: From 11 AM Saturday to 10 PM PDT Sunday.

    IMPACTS: This level of heat affects anyone without effective
    cooling and/or adequate hydration. Impacts likely in some health
    systems, heat-sensitive industries and infrastructure.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Hydration is a critical piece to surviving the heat. Drink water, and
    if possible, take water to those who are vulnerable.

    Take extra precautions when outside. Wear lightweight and loose
    fitting clothing. Try to limit strenuous activities to the early
    morning or evening. Take action when you experience symptoms of heat
    exhaustion and/or heat stroke.

    Coastal Flood Advisory - 7:39pm Thu Oct 1 2026

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

    WHAT: Up to 0.9 ft of inundation above ground level is
    possible in low-lying areas near shorelines and tidal waterways.

    WHERE: Bayshore locations along the San Francisco Bay, San
    Pablo Bay, and Monterey Bay.

    WHEN: Until 6 PM PDT Friday.

    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 0.9 ft above normal (6.7 ft MLLW) at 3:58 PM
    Friday 10/02. These predictions include up to 0.7 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.
