Event narrative

A narrow, vertical waterspout with an observed spray ring was reported approximately four miles north northwest of the Niles Channel Bridge. The waterspout was observed for a few minutes before it became tilted and more rope-like before dissipating.

Wider weather episode

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.
