Four major wildfires were burning in triple-digit temperatures across Arizona on Monday, torching about 125,000Â acres and forcing evacuations for some residents near the Tonto andÂ Kaibab national forests.
The Bush Fire, the largest of the blazes,Â swelled an additional 27,000 acres northeast of Phoenix on Tuesday, with 0% containment, forcing another round of evacuationsÂ
Hot and dry temperatures with low humidity levels are forecastÂ through the week, creating conditions that are for ripe for quick fire growth.Â
Fire crews were also working to contain wildfires in other corners of the state.
The Mangum Fire hasÂ burned close to 30,000 acresÂ with 3% containment just north of the Grand Canyon’s North Rim.
Near Tucson, firefighters were able to secure 30% containment of the 16,000-acre Bighorn Fire, which was ignited by a lightning strike inÂ the Santa Catalina Mountains.
The Bringham Fire, which has burned for 10 days in the Apache-Sitgreaves National Forest, had charred 14,625 acres as of Tuesday afternoon, with 5% containment.
The Bush Fire, which spread quickly over the weekend due to hot and dry conditions,Â had grown to approximately 64,513 acres as of Tuesday morning in the Tonto National Forest, prompting evacuations and multiple road closures.
Heavy smoke was expected to continue drifting over the Roosevelt Lake and Tonto Basin areas. The glowing lights of the flames could be seen from communities in Fountain Hills, according to pictures and worried comments on social media.
Officials said Monday that no structures had been damaged in the Bush Fire, and that firefighters are working to protect power lines and private property from the flames.
The Maricopa County Sheriff’s Office issued evacuation orders for the Sunflower and Apache Lake areas on Tuesday after Gila County evacuated communitiesÂ in Tonto Basin and Punkin Center on Monday.
The human-caused fire remains under investigation.
The Mangum Fire was 3% contained and burning 29,689 acres in the Kaibab National Forest as of Tuesday morning. Officials added that windy conditions would make firefighting efforts difficult throughout the day.

The Arizona Emergency Information Network reported three minor heat-related injuries due to the Bighorn Fire. No property had been damaged, but officials estimated 8,380 structures were threatened.
The lightning-caused wildfire has been burning through the steep and rugged terrain of the Coronado National Forest since June 5. Officials said Tuesday they are working to stop the fire’s momentum near Romero Pass, clearingÂ timber, brush and other fire fuel to “create solid, defensible space.”
The Bringham Fire has burned 14,625 acres in the Apache-Sitgreaves National Forest and was 5% contained as of Tuesday. Officials said the fire’s growth had recently slowed due to lower temperatures and cloud cover.
