A fast-moving brush fire that erupted near Lake Piru in Ventura County rapidly burned toward 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 an hour it was estimated by crews at the scene to have scorched roughly 600 acres.
With the fire advancing, evacuation warnings were issued in the Val Verde area. That warning was later elevated to an evacuation order, while some surrounding neighborhoods were placed under additional warnings.
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.
