Embers glowed in the night as crews worked to gain containment of a fire that spread quickly Sunday afternoon in Murrieta.
A command center was set up near the end of Hunter Road, past where a police roadblock was in place.
One RV and one shed were confirmed lost in the fire, according to Murrieta fire Chief Matt Shobert, but no primary residences.
No mandatory evacuations were in place, the chief said, and an evaucation center at Vista Murrieta High School had been shut down after no evacuees showed up.
About 35 homes were without power near Via La Colina, according to Southern Calfornia Edison. The outage was reported just after 5:30 p.m. and was expected to be restored by 3 a.m., according to SCE's website. It was unclear if the power outage was related to the fire, but the neighorhood is located near the fire lines.
The cause of the blaze was still under investigation, the chief said.
Crews were expected to remain on scene overnight knocking down hot spots and expanding the containment lines.
Winds had died down, which was working in firefighters' favor, Shobert said.
The fire was estimated at 150 acres; an official update on containment and acreage was not due until the morning, the chief said.
Schools in the Murrieta Valley Unified School District were expected to be open Monday.
"If anything changes we will send a phone call notifying parents," said Karen Parris, district spokesperson.

"This Fire is running from Temprano Park (Whitewood near my house) up the creek beside Murrieta Hot Springs Mobile Park heading towards Hogsback to Los Alamos Rd!
Bad Bad area to have a fire. Los Alamos is closed to Briggs Road and evacuations are in progress! Air support has stopped as darkness set in so ground crews, trucks are on site. Our home is safe! But pray for the folks in these areas!"
