Additional firefighters from around the region have been called in to assist in fighting the Doce fire in Prescott National Forest, the Mohave Valley Daily News reported Thursday.
The fire, which the National Fire Service said began Tuesday, has consumed 11 square miles of the forest. More than 500 homes northwest of Prescott have been evacuated.
Three members of the Bullhead City fire department, with their tactical brush truck, Wednesday were asked to fight the blaze, Battalion Chief Craig Stephenson said.
As of Wednesday afternoon, the wildfire was not contained at all.
Firefighters from the Mohave Valley Fire Department will be called in next if they are needed, Mohave Valley Battalion Chief Terry Thomas said.
Stephenson say two Bullhead City firefighters working the Colorado fire, along with their tender truck, may have to return if the Arizona fire continues to grow.
Officials say the Doce fire, about 100 miles north of Phoenix, has involved three air tankers, four helicopters, 16 crews and 27 engines, USA Today reported.
Winds of 18 to 20 mph have been blowing the flames away from Prescott, which is eight miles south of the fire, said Commander Tony Sciacca.
On Thursday, winds were forecast to reach 25 mph, with gusts of 30 mph.
