The Bay Area Air Quality Management issued a smoke advisory this morning because of the blaze. The smoke appears to be moving south and may affect residents in parts of Contra Costa, Alameda and Santa Clara counties, according to the air district.

re-circulate indoor air.
In another fire that started Sunday near the city of Sonoma, the spread of a more than 40-acre fire has been halted, but firefighters remain on the scene and road closures continue.
The brush fire, first reported on the right-hand shoulder of state Highway 121 north of Eighth Street East around 1:30 p.m. Sunday, grew rapidly, CHP Officer Anna Paulson said.
The fire centered around a pallet factory at the corner of Highway 121 and Fremont Drive. Several trailers in the area and warehouse structures
were destroyed, as well as factory equipment, Paulson said.
The fire damaged power lines and a transformer, causing a power loss in the area, Paulson said. PG&E is on scene.
A propane tank also exploded during the fire, Paulson said.
The fire's cause remains under investigation. Sparks were seen coming from a tow truck using a tow dolly in the area around that time, but it is unclear what caused the sparks, Paulson said.
Residents in one home close to Highway 121 at Fremont Road self-evacuated.
Road closures were in effect Sunday night on Highway 121 at state Highway 116 and at Eighth Street East, at Watmaugh Road and Broadway and at
Napa Road at Eighth Street East.
Motorists were being advised to avoid the area, but Paulson said traffic appeared to be only minimally affected in the area.
