KSDK – At least one person has died and scores more were injured after a pair of tornadoes struck a small Nebraska town on Monday.

Stormchasers caught numerous photos and videos of the storms, and NewsChannel 5 meteorologist Cindy Preszler says you may never see a pair of tornadoes like it ever again.

The storms are extremely rare, and many scientists don't know what causes them.

Usually when two tornadoes form in close proximity, one is significantly weaker and smaller, and eventually gets overtaken by the larger one. This time though, it didn't happen.
