    Coastal Flood Statement - 4:00am Thu Aug 13 2026

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

    WHAT: Minor saltwater flooding.

    WHERE: Lower and Middle Florida Keys.

    WHEN: Through Thursday afternoon, especially around the times
    of high tide in the late morning and early afternoon hours.

    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.
