    Weather Alerts
    Coastal Flood Advisory - 3:48pm Mon Nov 2 2026

    ...COASTAL FLOOD ADVISORY REMAINS IN EFFECT...

    WHAT: The next round of high tides will reach near 1.5 to 2
    feet above mean higher high water, especially in the Upper
    Keys. Additional rounds of heavy rainfall will increase the
    footprint of saltwater flooding.

    WHERE: Upper Keys.

    WHEN: Through Tuesday morning.

    IMPACTS: Saltwater flooding of low elevation streets and lots
    is expected. Some storm drains will overflow, and some
    seawalls and docks will be overtopped. Boaters can expect less
    clearance under fixed bridges. Motorists should remember that
    persistent puddles around the times of high tide are almost
    certain to contain a mix of saltwater.

    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.
