Brush fire near Lake Piru in Ventura County grows to more than 4,800 acres; evacuation orders issued

PIRU, Calif. (KABC) -- A fast-moving brush fire that erupted near Lake Piru in Ventura County rapidly burned into Los Angeles County Thursday, prompting evacuation orders in the Val Verde area west of Castaic.

The Canyon Fire erupted shortly after 2 p.m., burning in a remote area east of Lake Piru but spreading rapidly through the brush. Initially estimated at about 30 acres, the blaze grew rapidly, and within two hours it was mapped at 1,051 acres.

As of Thursday night, it exploded to more than 4,800 acres, according to officials.

With the fire advancing, evacuation warnings were issued in the Val Verde area. That warning was later elevated to an evacuation order and expanded to include the Hasley Canyon area, while some surrounding neighborhoods were placed under additional warnings.

Much of the area near Lake Piru is also under an evacuation order, including the area near Telegraph Road.

Fire crews from Ventura and Los Angeles counties were battling the flames, with assistance from Angeles National Forest personnel.

The National Weather Service reported that temperatures in the area were hovering around 100 degrees Thursday afternoon.

There was no immediate word on the cause of the fire, and no reports of any injuries.

Los Angeles County Supervisor Kathryn Barger, who represents the area and chairs the Board of Supervisors, issued a local emergency proclamation Thursday afternoon in response to the fire aimed at ensuring all resources are made available to fight the blaze.

Barger also urged residents in the area to heed evacuation orders.

"The Eaton Fire showed us how quickly devastation can strike,'' she said. "It is never worth risking your life, the lives of your loved ones and pets, or the safety of those working to protect you. Your safety is my top priority, and swift action saves lives.''
