An incredible photo of a massive storm cloud taken near Clareton, Wyoming, on May 18 has gone viral.

The image was captured by the Basehunters storm chasers group and shows a supercell thunderstorm.

Supercells are the least common type of thunderstorm, but they're the most severe class and can last for hours.

They're most commonly seen on the Great Plains and are caused by a rotating updraft, which is why they're sometimes called rotating thunderstorms.

Supercells have the capability to produce tornadoes, damaging hail and extremely strong winds.
