Of the 1,500 people evacuated, only a handful of people are staying at the Red Cross shelter in Lower Lake. The community has been hit with so many wildfires, they know the drill and have figured out where to stay. Others are camping.
The fire had burned around 8,200 acres as of 7 a.m. Monday and there was 0 percent containment, fire officials said. The fire was being driven by low relative humidity, erratic winds and above-normal temperatures, but fire officials said overnight humidity should be around 60 percent.

Fire departments from around the Bay Area, including Alameda County, Berkeley, Fremont, Hayward and Oakland, have sent crews to battle the blaze.
The cause of the fire is under investigation.
