Illinois and Indiana Tornado on March 10 Near Momence and Kankakee Traced Unusual Looping Anti Cyclonic Path With No Damage Reported

MOMENCE, ILLINOIS — A highly unusual tornado that occurred on March 10 near Momence has drawn attention after satellite imagery revealed a rare looping and anti-cyclonic path stretching across parts of Illinois and Indiana.

The tornado developed north of a stronger EF-3 system that tracked from Kankakee, Illinois, through Lake Village, Indiana, but stood out due to its uncommon behavior and lack of visible damage.

Tornado Followed a Rare and Unusual Path

Unlike typical tornado tracks that move in a relatively straight or slightly curved line, this tornado displayed a “wonky” path that included a loop — a feature rarely observed in tornado events.

The track shows the tornado moving across southeastern areas near Momence before looping back on itself, creating a distinctive pattern visible on mapping and satellite data.

Anti-Cyclonic Rotation Makes Event Even Rarer

What makes this tornado even more unusual is its anti-cyclonic rotation. Most tornadoes in the Northern Hemisphere rotate counterclockwise, but this system rotated in the opposite direction.

Anti-cyclonic tornadoes are extremely rare, accounting for only a small percentage of all tornado occurrences, making this event particularly noteworthy for weather observers.

Rated EF-U Due to Lack of Damage

Despite its unique characteristics, the tornado was classified as EF-U, meaning it could not be assigned a traditional rating on the Enhanced Fujita scale.

This classification was given because no structural or environmental damage was found along its path. Without damage indicators, meteorologists rely on alternative methods to confirm the tornado’s existence.

Identified Only Through Satellite Swirl Marks

The tornado’s presence was ultimately confirmed through high-resolution satellite imagery, which revealed distinct swirl marks on the ground.

These marks provided the only evidence of the tornado’s track, highlighting how some tornadoes can occur without causing noticeable damage but still leave behind detectable signatures.

Connection to Larger EF-3 Tornado Event

The rare tornado occurred in proximity to a more powerful EF-3 tornado that moved from Kankakee, Illinois, into Lake Village, Indiana.

While the EF-3 caused a more traditional and trackable impact, this secondary tornado formed separately and behaved in a dramatically different way.

Why This Event Stands Out

This event is a reminder that not all tornadoes follow predictable patterns. The combination of a looping track, anti-cyclonic rotation, and lack of damage makes this one of the more unusual tornado cases observed in the region. It also highlights the growing role of satellite technology in identifying weather events that might otherwise go unnoticed.
