Brush Fire Between Olinda Ranch and Olinda Village

Within the last 10 minutes, alerts have been issued of a brush fire in Brea, between Olinda Ranch and Olinda Village. Because of gusty winds, the flames have been moving toward the latter and several acres burned at last report. The fire response includes a variety of equipment and Carbon Canyon Road is closed while the blaze is being battled.

From the Orange County Register:

Firefighters on Saturday afternoon, April 25 were battling a wind-driven vegetation fire that scorched 4 acres in Brea, authorities said.

The blaze, dubbed the Carbon Fire, was reported around 1:45 p.m. on the north side of Carbon Canyon Road, according to Watch Duty, a nonprofit app that tracks wildfires. The fire quickly spread to 4 acres, and was approaching the neighborhood of Olinda Village.

Carbon Canyon Road was closed down between Brea Hill and Ruby, the Brea Police Department announced.

An additional five engines, two tankers and a helicopter were requested by incident command to combat the blaze.

From NBC4 Los Angeles a little before 3:30 p.m.:

Evacuation warnings were issued Saturday afternoon after a brush fire broke out in an unincorporated area of Brea.

The Carbon Fire was reported just after 1:30 p.m. in the area of Carbon Canyon and Olinda Place near Carbon Canyon Regional Park, according to the Orange County Fire Authority.

The blaze, which is currently at about 5 acres, prompted officials to issue an evacuation warning for Hollydale Mobile Home Park and Olinda Village. The public is asked to avoid the area until further notice.

As a result of the firefight, Carbon Canyon Road is closed between Ruby Drive and Break Hills Avenue.

It’s unclear what caused the fire.

Further updates, 6:30 p.m.: The Carbon Fire, involving some 200 acres, burns toward the north, apparently in Chino Hills State Park and other land, away from Olinda Village. Further firefighting resources have been requested in the form of 20 engines, 4 hand crews and 2 dozers. The City of Brea, it is reported, is keeping Carbon Canyon Road closed until tomorrow (Sunday) afternoon.
