SAN FRANCISCO (CBS SF) -- There were about 20 spot fires burning Monday in wildland areas in Sonoma, Solano, Lake and Colusa counties, Cal Fire spokeswoman Suzanne Blankenship said Monday afternoon.
The largest fire had burned roughly 2 acres west of Williams in Colusa County, Blankenship said. Thirteen of the blazes were 100 percent contained as of about 1 p.m., she said.
Of the 20 fires, 13 are in Sonoma County. Eight of those fires are burning off state Highway 128 in the Geyserville and Knights Valley areas, Blankenship said.
Four fires were reported in Solano County, two in Lake County and one in Colusa County. The counties are in Cal Fire's Sonoma-Lake-Napa area.
The cause of the fires remains under investigation, but they were reported at first light Monday morning after numerous lightning strikes in the North Bay overnight, Blankenship said.
The fires are burning in remote areas that are difficult to access. Additional resources were en route and all roads remained open.
There have been no injuries and no structures have been damaged, Blankenship said.
