A wildfire in eastern Arizona jumped containment lines and spread to 5,000 acres Friday afternoon, endangering 90 structures, fire officials said. Nine Hotshot crews and additional firefighters were battling the fire, which broke out on Thursday night just east of the Apache-Sitgreaves National Forest, said Pamela Baltimore, a U.S. Forest Service spokeswoman. Two nearby towns were under evacuation warnings, and the Grand Canyon American Red Cross opened a shelter for displaced residents, according to the organization.

The blaze is burning through areas that burned before or had been thinned in an effort to reduce fuel for wildfires, reported.

Temperatures were expected to soar into the mid-90s on Saturday and Sunday, according to The fire is thought to be human-caused.
