Firefighters had contained 5 percent of Arizona's massive Wallow fire and established containment lines on its northeast side, authorities said Saturday.

The fire has already reached 627 square miles (3963960 acres). There are over 3,200 personnell attending to the fire.

The number of residences threatened dropped to 2,714 from over 5,000 a day earlier. So far 63 structures have been destroyed including 29 residences. There have been 6 reported injuries.

However weather conditions will provide renewed challenges as wind gusts as high as 33 miles per hour are expected in the town of Eagar, according to the National Weather Service. The town has been evacuated due to concerns about the fire.

Improved weather conditions allowed responders to perform successful burnout operations along the 273 road near Greer, in Water Canyon south of Eager, and northeast Alpine, according to Area Command 3.

Firefighters on Saturday will work to protect additional structures, continue with burnout and mop operations to strengthen already established containment lines, while patrolling for any sport fires.

In addition, the unincorporated town of Luna just across the border in New Mexico will continue with burnout operations along Highway 220.
