The wildfire also destroyed one home and injured two firefighters.
On Monday, Cecile Juliette with CAL FIRE said Monday crews were making good progress compared to Saturday when the fire broke out.
Juliette said they were able to take advantage of higher humidity and cooler temperatures Sunday morning and grew containment lines Sunday night.
However, she warned of the heat wave that will dry everything out even more.

Evacuation warnings were lifted as of 6 p.m. Monday, according to CAL FIRE.
Two Alameda County firefighters were hospitalized for treatment of minor to moderate burns Saturday but are expected to make a full recovery.
Juliette wants residents to be prepared with evacuation routes and have their go-bag ready.
She warned Bay Area residents of wildfire safety, noting the size and magnitude of this fire in early June when most activity is around July, August and September.
"This should highlight how dangerous firefighting is, and how dangerous it is for anyone to be near a fire, so what we're asking people is just to really pay attention to evacuation orders and to get out early because we're going to be coming in if there's a fire," Juliette told ABC7 News. "All fires start small so our goal is to get in there quickly so that we can keep it small, get it out and hope that people can get back into their homes quickly."
The cause of the fire is still under investigation.
