PALMDALE – A brush fire blackened 150 acres and threatened several outbuildings before firefighters had it fully contained tonight, authorities said. The fire, which began at North 47th Street East and Mount Emma Road just after 3 p.m., was completely contained as of 10:10 p.m., said Los Angeles County Fire Department Inspector Jason Hurd. Winds out of the southwest were pushing the fire east at about 10 mph in 95-degree heat, and it jumped from 25 to 50 acres in a slightly more than an hour, a county fire dispatcher said. The blaze was threatening some structures, but according to ABC7, there were only a few outbuildings in the area and no homes. No injuries were reported. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set!
