The Chaparral Fire grew very quickly after it started at about 12:30 p.m. Saturday afternoon in northern San Diego County in Southern California. By 5:30 it was mapped at 1,200 acres.
The fire is near Cold Springs Road and Tenaja Road in the community of La Cresta. It is just north of Camp Pendleton, 10 miles west of Temecula, and 12 miles east of San Clemente.
Many structures are threatened and mandatory evacuations are in place. A map is available showing the evacuation areas.

Firefighters on the ground initially had difficulty in gaining direct access in the remote area of the Cleveland National Forest. In the early hours it was completely in San Diego County, but was spreading toward Riverside County which was not far away to the east
Early on, eight air tankers were assigned, including two DC-10 Very Large Air Tankers. Later a third DC-10 was dispatched. That was a large aviation commitment considering the fires ongoing in Northern California. The Air Attack over the fire requested a “no divert” for some of the VLATs and other large air tankers due to life and property that were in danger. If approved, that would prevent the dispatcher from pulling them off the fire to respond to another fire.
At 4 p.m. the humidity began increasing at the Case Springs weather station west of the fire, from 22 percent at 3:22 p.m. to 50 percent at 6:22, and the smoke column started to diminish. Haze or low clouds at times obscured the view from the San Clemente South camera. This type of weather change can slow the spread of a wildfire.
