Multiple brush fires with "dangerous rate of spread" have prompted evacuation orders Sunday and early Monday in Napa and Sonoma counties, firefighters said.
The main blaze, called the Glass Fire, has burned at least 11,000 acres across the two counties with no containment, Cal Fire said Monday morning. Fire crews from across the Bay Area are also responding to the blaze for mutual aid. More than 8,500 structures are threatened.
The Shady Fire, which started as a separate fire west of St. Helena and was burning into the Oakmont area of Santa Rosa, was combined with the Glass Fire, Cal Fire said. The Boysen Fire was burning northeast of Santa Rosa.
Around 2 a.m. Monday structures were burning in the Skyhawk and Oakmont Village neighborhoods of Santa Rosa. Within a half hour, structures were burning at the intersection of Highway 12 and Melita Road in Santa Rosa.
The fire jumped Highway 29 across the Napa Valley on Sunday and was seen burning behind the Culinary Institute of American in Saint Helena, near the Charles Krug Winery, as strong winds, high temperatures and low humidity persisted in the heavily forested area.
The California Highway Patrol reported issues with traffic congestion as people fled evacuation zones and the blaze moved quickly toward St. Helena.

Cal Fire said the blaze started in the area of North Fork Crystal Springs Road near St. Helena and Deer Park.
