Wildfires in US West spur ‘fire clouds’ along with Grand Canyon “mega fire”
Two wildfires burning in the western United States are so hot that they are spurring the formation of “fire clouds” that can create their own erratic weather systems.
In Arizona, a superhot wildfire system has already destroyed the iconic Grand Canyon Lodge is responsible for burning 164 sq miles. It is one of the top ten recorded in Arizona history.
An emergency was declared in Utah as a megafire near Monroe continued to consume 75 sq miles. Evacuation orders for several towns Utah in the fire’s path, as burned up power lines caused electricity to be shut off in communities in south-central Utah.
Towering convection clouds known as pyrocumulus clouds have been spotted over Arizona’s blaze for seven consecutive days, fueling the fire with dry, powerful winds, fire information officer Lisa Jennings said. They form when air over the fire becomes superheated and rises in a large smoke column. The giant menacing anvil shaped clouds can be seen for hundreds of miles away..
