Watch: Spectacular Time Lapse Footage of Supercell Forming

Storm chasers in eastern Wyoming Sunday captured stunning time lapse video of a massive “supercell” thunderstorm, right as it formed before their very eyes. These storms, called supercells because of their rotating updraft, are responsible for the most destructive tornados in the United States, the National Weather Service reports.

The storm in the video thankfully did not touch down, but it’s easy to see the frightening power of those rapidly spinning clouds, and imagine the damage it might have inflicted, had it done so.

The video was captured and shared on social by Basehunters out of Norman, Okla.
