Event & radar context
Skywarn Poland observers identified a tornado associated with a shallow-mesocyclone supercell near Gniezno. Contemporary reports describe overturned vehicles and tree damage. The radar timeline shows 90 minutes of storm context, not time on the ground. Native IMGW reflectivity composites retain five-minute sampling and roughly one-kilometre cells. The archive does not provide radial velocity or RhoHV through this composite product; no tornado path has been inferred from the radar.
Interpreting the rating
F, EF and IF are different damage-rating scales. Original source labels are preserved. Badge colours group the numerical categories for browsing; they do not imply identical wind thresholds. Radar products do not directly establish the damage rating.
