At least 10 Cal Fire engines from the Sonoma-Lake-Napa Unit and air support tankers were battling the blaze. Video on social media showed a massive wall of flames rolling through the rural countryside.

Tinder-dry vegetation from the local drought conditions was fueling the flames. Cal Fire officials said the blaze had a “dangerous rate of spread.”

Local authorities have ordered residents from home in an area stetching from 3308 Sites Lodoga Rd. and Squaw Creek Rd. in Colusa County.
