Ridge Fire in northern Los Angeles County forces complete closure of I-5

A brush fire near Gorman in northern Los Angeles County has prompted the full closure of  I-5 as crews work to slow the spread, according to authorities.

The blaze, dubbed the Ridge Fire, was first reported at 3:02 p.m. and quickly spread to about 100 acres by 3:41 p.m.

It was not immediately clear if any structures were threatened or injuries were reported, but according to Cal Fire, evacuation warnings were issued in the following zones:

Los Angeles County

• GOR-E001-A
• GOR-HUNGRYVALLEY-A

Kern County

• KRN-545

A map of evacuation zones can be found here.

"An EVACUATION WARNING has been issued if you are along I-5 freeway between Highway 138 and LA County line," the Los Angeles County Sheriff's Department said. "PREPARE to leave if you live here or are nearby. Consider leaving now if you need more time to evacuate."

Images captured by a camera operated by ALERTCalifornia and UC San Diego showed large plumes of smoke covering the hillsides.

The Los Angeles County Fire Department initially requested that the northbound lanes of I-5 be shut down between Vista Del Lago and Smokey Bear roads. The southbound lanes were later closed, with traffic being turned around at Frazier Mountain Park Road.

It's not yet clear when the roadway will reopen.

I-5 is a major roadway between Southern California and Central and Northern California.
