Fire crews remained at the site of a 120-acre brush fire early Wednesday in Acton, hours after the fire burned a mobile home and other structures.
As of 11 p.m., the fire was 100 percent contained, fire officials said, but that does not mean all the flames were extinguished so crews remained at the site overnight.
No injuries were reported, but a mobile home, out-building, two storage sheds and two vehicles were destroyed in the blaze. About 30 homes were evacuated.
At one point, the brush fires appeared to be staying within a tree-lined perimeter along Metrolink tracks in Acton, where winds started picking up Tuesday afternoon.
Several pockets of infernos dotted the area near the 4700 block of West Crown Valley Road. Flames were also seen in the area of Bootlegger Canyon, Olsen Road, and the 29000 block of Hefner Road.
The fire was about 40 percent contained as of 8:25 p.m., according to fire officials.
Sheriff's spotted the flames around 4 p.m. and what started as a 3-acre blaze was quickly elevated to a third alarm blaze because of the threat to structures in the area, according to fire officials.
First-responding units recorded winds of 5 mph, but within an hour, wind speeds had picked up to 10 to 15 mph, said Capt. Mark Savage with Los Angeles County Fire Department.
Evacuations were being ordered as needed, Savage said, adding that if residents have large animals or think they are too close to the flames, they should be ready to go.
U.S. Forest Service units joined more than 370 fire officials to battle the blaze.
The fire forced the closure of Metrolink tracks north of the Via Princessa station. Buses will be provided for Action, Palmdale and Lancaster stations, according to a Metrolink advisory.
