WHAT: Atmospheric conditions could produce increased tornadic activity, including rotating thunderstorms and supercells, across parts of North Florida.
WHEN: Oct 9, 2026

WHY: The approaching tropical cyclone, combined with favorable wind shear and daytime heating, could support rotating thunderstorms and supercells away from the storm’s center.
