LAKE ELSINORE, Calif. (KNX) — A large brush fire that broke out on the border of Riverside and Orange Counties Wednesday is now 50% contained in the Cleveland National Forest, fire officials said Friday.
The 553-acre fire broke out around 11:06 a.m. Wednesday, in the Holy Jim Canyon area of Trabuco Ranger District, near Santiago Peak, officials said in a statement. It's said to have started in a drainage at the bottom of the area and spread uphill, consuming more than 400 acres of vegetation in just three hours.

"Overnight no fire activity was observed. [Thursday] firefighters made good progress bringing containment to 50%," forest officials wrote on the fire's incident page.
"[Friday] crews will continue to construct containment lines around the fires perimeter. If needed, firefighters will use helicopters to douse any hotspots along the fires edge or within the interior of the burn. Air tankers will be on standby if needed."
Fire officials said precipitation forecast over the fire area should assist in any smoldering areas of the fire.
The cause of the fire, which was not threat to any structures or nearby cities, remains unknown.
