    Marine Weather Statement - 1:52pm Tue Aug 4 2026

    ...CONDTIIONS FAVORABLE FOR WATERSPOUT FORMATION NORTH OF THE ISLAND CHAIN...

    The areas affected include...
    Hawk Channel and Straits of Florida from west end of Seven Mile
    Bridge to Halfmoon Shoal out 20 nm...
    Bay and Gulf Side from Craig Key to Halfmoon Shoal out to 5
    fathoms...
    Florida Bay including Barnes Sound, Blackwater Sound, and Buttonwood
    Sound...

    At 149 PM EDT, National Weather Service meteorologists detected
    conditions favorable for waterspout formation along an island cloud
    line north of the Island Chain. A trained spotter reported a
    waterspout in the vicinity of Sugarloaf Key with a defined spray
    ring. Conditions will be favorable for additional waterspout
    formation.

    Locations that will be affected include...
    Coon Key, Annette Key, Howe Key, Twin Keys, Snipe Point, Cottrell
    Key, and End Key.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Prepare for thunderstorms with wind gusts near 30 knots, locally
    rough and confused seas, occasional lightning strikes, and
    potentially blinding downpours. Get to a safe port as quickly, and as
    safely as possible. When downpours reduce visibility, slow down.

    Environmental conditions favor waterspout formation. A waterspout
    would most likely appear beneath a dark, flat bottom of a building
    cumulus line, just at the hint of rain. If you see a waterspout, stay
    away, and call in the report to your Florida Keys National Weather
    Service, at 3 0 5 2 9 5 1 3 1 6 extension 3.
