WICKENBURG, Ariz. (AP) -- A fast-moving brush fire charred about 1,000 acres by Wednesday night and forced the evacuation of at least 30 people from their homes near Wickenburg, authorities said.
The Bobby fire was burning dry grass and brush 20 miles south of Wickenburg and threatening about 30 mobile homes, cabins and other structures scattered throughout the area, according to authorities.
Up to 70 more residents may be affected if the flames moved closer to their homes, said Ken Palmrose, a spokesman for the Bureau of Land Management.
But by late Wednesday night, Palmrose said there were no reports of any injuries or structures lost to the fire.
''The fire is laying down nice'' due to cooler nighttime temperatures and not growing in size, Palmrose said.
Palmrose said the fire was on BLM and private land, and authorities had already determined that the blaze was human-caused.
The blaze was reported at 12:35 p.m. Wednesday and was burning in the same area south of Wickenburg as two recent brush fires, one of which charred three homes earlier this week.
Palmrose said more than 100 firefighters were battling the Bobby fire along with three heavy air tankers, five single-engine aircraft and two helicopters.
Crews were trying to build fire lines overnight and by Thursday morning, Palmrose said 25 engines were expected to be on the scene.
