Four major wildfires are burning in triple-digit temperatures across Arizona, torching over 150,000 acres and forcing evacuations for some residents near the Tonto and Kaibab national forests.

The Bush Fire is now the largest active fire in the nation and the 7th largest in Arizona history, at 89,000 acres.

The Mangum Fire near the Grand Canyon's north rim has burned over 47,000 acres, and the Bighorn Fire in Tucson has burned over 17,000 acres as of Wednesday morning.

This year, more wildfires have occurred in Arizona than in 2019 partly due to more moisture over the last two years and an overgrowth of grass vegetation.

Hot and dry temperatures with low humidity levels are forecast through the week, creating conditions that are for ripe for quick fire growth.
