Evacuations have been ordered for areas northeast of Phoenix as a raging wildfire more than doubled in size Monday, and two other large blazes continued to burn in Arizona.

The Gila County Sheriff's Office said in a news release that the communities of Tonto Basin and Punkin Center have been ordered to evacuate as the Bush Fire grows in Tonto National Forest.

As of Tuesday morning, the blaze northeast of Phoenix was just over 64,513 acres with zero percent containment. The sheriff's office said those in areas under evacuation orders face "imminent" and "life-threatening danger."

"If you choose to ignore this advisement, you must understand emergency services may not be able to assist you further," officials said.

Increased humidity on Monday showed the spread of a fire that's been burning since June 5 outside of Tuscon.

Officials said a "large contingent" of engines and crews continued preparatory work around the community of Summerhaven to make a fire line. Around 729 fire personnel are involved in the response.

"Threats to the East Golder Ranch and Saddlebrook communities have greatly diminished due to the direct suppression work conducted by crews and air operations over the past several days," officials said on a Facebook page set up for fire updates. "Residents will continue to see firefighters in the area patrolling and doing additional preparation around communities that border the north and south edges of the fire."
