By morning, the fire posed little risk to the facility with a cleared buffer zone, Zaniboni said.

New Mexico Dog Head and North Fires

Southeast of Albuquerque, New Mexico, the Dog Head Fire, which broke out on Tuesday about 6 miles northwest of the town of Tajique, has also forced evacuations and grown to about 16,000 acres overnight. The fire destroyed 24 homes and 21 other structures, InciWeb reported.

New Mexico's Torrance County Sheriff Heath White said on Thursday that his office was evacuating about 200 people.

The largest of these fires, the North Fire, has burned more than 26,000 acres in the San Mateo Mountains of southwestern New Mexico over the course of nearly a month. The lightning-caused North Fire started May 21 in the Cibola National Forest and is only 30% contained.

Cedar Creek Fire in Arizona

A wildfire near Show Low, Arizona, started Wednesday and swiftly grew in size. The so-called Cedar Creek Fire has burned nearly four square miles of brush and timber in rugged terrain about nine miles from Show Low, and thousands of area residents remain under pre-evacuation advisories.

Navajo County spokesman Adam Wolfe said only about a dozen people have been evacuated.

Heat wave

The weather service issued excessive heat warnings for areas in the U.S. Southwest, including California, Nevada and Arizona and New Mexico. Its forecast office in Phoenix predicted temperatures as high as 119 degrees Fahrenheit in the coming days, which would exceed record highs.
