Canyon Fire: Fast-moving brush fire burning near Lake Piru in Ventura County; officials monitoring evacuation orders

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.
