A fast-moving brush fire has triggered evacuation warnings after it tore through the Antelope Acres area Friday afternoon, torching roughly 1,600 acres as flames pushed from Los Angeles County into neighboring Kern County.
Dubbed the Macy Fire, the blaze ignited near North 110th Street West and Highway 138, according to the Los Angeles County Fire Department.
Driven across county lines, the fire prompted officials to warn residents south of Rosamond to prepare to leave.
Evacuation warnings were issued in Kern County zones KRN-152-A and KRN-153-A, as well as Los Angeles County zones LAC-E1641, LAC-E1642 and LAC-E1639.
Authorities directed residents to check official maps for the latest evacuation boundaries.
By 7:45 p.m., fire officials announced that forward progress of the blaze had been stopped, a critical milestone in the firefight.
Even for those outside evacuation zones, authorities urged caution.
Residents in nearby communities were advised to stay indoors, shut all doors and windows, and turn off air conditioning units to reduce smoke exposure.
The cause of the fire remains under investigation.
