Cabin Fire Map: Fire Burns North of Azusa, Glendora Today

About 500 homes were threatened, according to Capt. Mike Lindbery of the Ventura County Fire Department but no evacuations have been ordered.

Earlier in the day, shortly after the fire broke out, aerial video from Sky5 showed at least one structure burning, with black smoke rising from the building.

When there is a fire in the area it is not uncommon for the campgrounds to be evacuated and that was the case in this situation.

People around the San Fernando Valley, Hollywood Hills, Studio City and Mount Olympus are smelling smoke and calling 911 thinking there is a wildfire near them, says the Los Angeles Fire Department’s Brian Humphrey.

West Fork Area, East Fork Area, Coldbrook and Crystal Lake Campgrounds have been evacuated.

Southern winds of 15 miles per hour quickly drove the flames up ridges and through 100 acres of brush. But that was poised to change at any moment.

Aircraft equipped to conduct water drops at night were yet to be requested, Seastrand said late Friday afternoon, though that also could change at any time.

The Cabin Fire started just after noon today.

Police in Azusa and Glendora sent advisory messages to residents saying the blaze was not threatening either city. Two firefighters were being treated for heat exhaustion.

An excessive heat warning in effect through Sunday means an elevated fire danger due to hot, dry and windy conditions, National Weather Service officials said.
