FLAGSTAFF, Ariz. (AP) - A wildfire north of Flagstaff grew overnight as crews tried to prevent it from spreading.
U.S. Forest Service officials say the city and surrounding communities will likely experience heavy smoke on Monday as crews attempt contain the blaze, which was about 1.6 square miles (4.1 square kilometers).
More than a dozen aircraft including four air tankers have been dispersing fire retardant and water. Ground crews are also working to establish containment lines.
The blaze prompted a pre-evacuation notice on Sunday for the area of Forest Road 420 to Friedlein Prairie.
A Red Cross shelter has been set up at Sinagua Middle School.
Roughly 200 firefighters are fighting the fire.
It was first reported July 12. The cause has not yet been determined.
