RIVERSIDE (CBSLA.com)  — A brush fire that started Thursday afternoon in the Santa Ana River bottom is 40 percent contained as of Friday.

The fire, which was sparked around 4:45 p.m. Thursday at Rio Road and Calle Hermosa in Rancho Jurupa Park, has destroyed more than 300 acres.

More than 200 firefighters from various agencies have been fighting the Jurupa fire which has damaged a home and a trailer.

Officials called for a voluntary evacuation, but it was lifted late Thursday. Approximately 2,000 homes were without power overnight.

“I’m shakin’ like a leaf. I’m upset ’cause the fire could have come over into the house, it was that close,” a resident told CBS2.

No injuries have been reported.

It is unknown when the fire will be fully contained. Officials worry the weather could help fuel the fire Friday.

“We anticipate that it’s gonna get warmer, it’s gonna get dryer, we’re gonna have winds. That always makes this a challenge,” Deputy Fire Chief Mike Esperanza of the Riverside Fire Department said.

The cause of the brush fire is under investigation.
