    Weather Alerts
    Small Craft Advisory - 4:55pm Fri Oct 23 2026

    ...SMALL CRAFT ADVISORY IN EFFECT...

    WHAT: Northeast winds 20 to 25 kt with gusts up to 30 kt and
    seas 5 to 8 ft expected.

    WHERE: Straits of Florida, Hawk Channel, Gulf waters
    including the Dry Tortugas, and Florida Bay.

    WHEN: In Effect.

    IMPACTS: A Small Craft Advisory means that wind speeds of 20
    to 33 knots, or seas of 7 feet or greater, are expected to
    produce hazardous conditions for small craft. These hazardous
    conditions may result in poor vessel handling and steering
    response, broaching, overturned dinghies and kayaks, slips and
    falls on slippery decks, rub damage along docks and seawalls,
    swamped bows at reef tract mooring balls, and dragging anchors.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Inexperienced boaters, especially those with smaller vessels,
    should avoid operating in these conditions.

    &&

    Coastal Flood Advisory - 9:07am Fri Oct 23 2026

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

    WHAT: Moderate Saltwater flooding.

    WHERE: Middle Keys.

    WHEN: During times of high tide through Saturday 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.
