‘Fire Clouds’ Over Arizona And Utah Wildfires Make Erratic Weather Systems

"Containment slips for megafire in Grand Canyon and large blaze in Utah as hot and dry weather fans flame" 

"SALT LAKE CITY — 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.

In Arizona, the wind-whipped wildfire that destroyed the Grand Canyon Lodge is 9% contained and has charred more than 164 square miles (424 square kilometers) to become the largest fire now burning in the continental U.S. and one of the top 10 largest in recorded Arizona history. Getting around it would be roughly like driving from New York City to Washington, D.C.

Another large fire in Monroe, Utah, has burned 75 square miles (194 square kilometers) since July 13 and is 11% contained, officials said Thursday. Evacuation orders were issued Wednesday for several towns in the fire’s path, and scorched power poles caused electricity to be shut off in other nearby communities in south-central Utah."
