A northwest wind gust of 47 knots was recorded at the Florida Keys Marathon International Airport.

The wider storm

Showers and thunderstorms originating in weak, nebulous lower to middle tropospheric steering flow on the afternoon of September 12, 2025, produced isolated gale force wind gusts and a waterspout near the Lower Florida Keys. The showers and thunderstorms eventually evolved into a mesoscale convective system over the southeast Gulf of America featuring a large southward-moving outflow boundary bringing scattered gale-force wind gusts through much of the Florida Keys coastal waters the evening of September 12 to the early morning hours of September 13, 2025.

Began near Marathon (24.7224, -81.0620).
