SURPRISE, AZ — Firefighters say a brush fire that ignited Friday afternoon has grown to an estimated 1,200 acres.
The Dove Fire started near 167th Avenue and Dove Valley Road and started spreading among desert shrubs and grasses.
The Arizona Department of Forestry and Fire Management, which assumed command over operations, said it was estimated to be 1219 acres as of 6:47 p.m. on Saturday.
"Firefighters worked overnight conducting back burn ops, which increased the fire size to 1,200 acres," the Arizona Department of Forestry and Fire Management tweeted on Saturday.
The fire is 90 percent contained, and has "decreased immensely," according to the Arizona Department of Forestry and Fire Management. Fire officials added that full containment is expected on Monday.
The investigation has determined the fire was human-caused, but it is still an ongoing investigation.
Fire officials said while fire activity is minimal, smoke may continue to linger in the area.
Video from the Cliff Castle Chopper shows the flames moving away from homes and other structures.
Smoke from the fire was detected by weather satellites maintained by the National Weather Service.
