    Coastal Flood Statement - 4:00am Mon Oct 12 2026

    ...COASTAL FLOOD STATEMENT REMAINS IN EFFECT...

    WHAT: Minor saltwater flooding.

    WHERE: Florida Keys.

    WHEN: Through this afternoon.

    IMPACTS: Minor saltwater flooding of low elevation streets
    and lots is likely. 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:

    Do not drive through flooded roadways.
