A quick-moving wildfire is churning through the foothills of Southern California, forcing local authorities to issue mandatory evacuations for some 100,000 people in the San Fernando Valley north of Los Angeles.
The blaze, which officials have named the Saddleridge Fire, ignited late Thursday in the city of Sylmar. By Friday morning, it had torched roughly 4,700 acres, according to the latest alert by the Los Angeles Fire Department.
"This is a very dynamic fire," Los Angeles Fire Chief Ralph Terrazas said at a Friday morning press conference.
At least 25 structures have been destroyed and more property assessments are planned throughout the day.
