SAN FRANCISCO (AP) - More firefighters are arriving to help as crews struggle to contain a massive wildfire that's burning in Northern California's Colusa County.
Fire officials say two separate blazes - being called the Sixteen Complex fire - are threatening 23 residences and several outbuildings.
Since the fires broke out Tuesday they have consumed more than 26 square miles.
California Department of Forestry and Fire Protection Daniel Berlant says firefighters are working against gusty winds and low humidity as they try to contain the fires burning in rugged terrain of grasslands, brush and oak trees about 60 miles northwest of Sacramento.
An evacuation advisory is in effect for the nearby Cortina Indian Rancheria and parts of Highway 16 are closed.
The two fires are one of several fires burning in Northern California.
