Update—12:40 p.m. Dec. 7: : The Lilac Fire burning in the Pala Mesa area is now estimated between 100 and 150 acres with zero containment. Two structures have been destroyed and 12 others damaged, reports Cal Fire.
The wind-driven wildfire started about 11:15 a.m. amid gusty, arid Santa Ana conditions just south of state Route 76, according to Cal Fire.
Within an hour, the burn area had grown to about 50 acres as ground and airborne crews labored to keep the blaze from becoming a devastatingly out-of-control conflagration like others raging this week across Southern California.

The cause of the fire was not immediately clear.
