A supercell storm's clouds in Wyoming have gone viral after a photo and time-lapse video of the natural phenomenon took off on social media this week.
A group called Basehunters recorded and posted the clip on their Facebook and YouTube pages Sunday, where it quickly gathered more than 9 million hits.
In the time-lapse video, a towering column of black clouds swirls and then converges into what's called a supercell.

The National Weather Service said supercell storms "contain updrafts
that rotate about a vertical axis," which is what creates the impressive swirling effect.
"Supercells often produce damaging wind, large hail, and tornadoes, and most strong to violent tornadoes are associated with supercells," according to the NWS. "Once formed, a supercell may perpetuate itself for an appreciable length of time, even upon encountering an environment that is hostile to the development of new storms."
Despite the danger associated with such storms, photographs and video of supercells are popular online.
"The video of this supercell forming is pretty amazing. Personally I would be headed in the opposite direction. #tornadoes #supercell," one YouTube user commented on the Basehunters video.
The Basehunters’ supercell video went viral the same week as the anniversary of the destructive storm and tornado that hit the Moore, Oklahoma, area and killed 24 people last year. On its Facebook page, the Basehunters posted a video they took of that tornado and wrote, "Thoughts and prayers continue to go out to the residents of Moore & OKC on this one-year anniversary."
