Two wildfires burning in the western United States — including one that has become a “megafire” on the North Rim of the Grand Canyon — are so hot that they are spurring the formation of “fire clouds” that can create their own erratic weather systems.

Wildfires burning at the Grand Canyon and in Utah are so hot that they're spurring the formation of "fire clouds" that can create their own erratic weather systems.

Both it and the Monroe Fire, burning further north near Monroe, Utah, are generating pyrocumulus clouds — sometimes called "fire clouds" — that form when air over a fire becomes superheated and rises in large, smoky columns. The massive clouds are visible for hundreds of miles and resemble the shape of an anvil.

A video shared by a local fire emergency team shows thick plumes of orange-hued smoke rise into the sky creating a fire cloud.
