The tornado that hit the Kankakee area on March 10, 2026 was a large, violent tornado that reached roughly around a mile in width at its peak, according to early storm-chaser and media descriptions, with official National Weather Service details still being finalized.

Because your question is framed like a current-news / forum topic, I’ll answer in that style and keep it focused.

Quick Scoop: How big was the tornado in Kankakee?

  • A strong tornado struck near Kankakee and Aroma Park on March 10, 2026.
  • Preliminary surveys from the National Weather Service (NWS) describe an EF3 tornado that tracked from just west of Aroma Park, IL into northwest Indiana, with a path nearly 40 miles long.
  • Multiple storm chasers on the ground have described and filmed it as “over a mile wide” or “mile-wide” at peak intensity, which matches how it appears on video and radar imagery, though exact official width numbers have not yet been formally published.

So in plain terms: it was a very large tornado, roughly around a mile wide at its largest, with a long track and EF3-level damage, and some official measurements are still being refined in post-storm surveys.
