Cal Fire said in a Sunday morning update that fire growth was moderate overnight and that five night-flying helicopters had helped crews on the ground slow the eastward spread in the Aetna Springs and Pope Valley.
Vegetation in between eastward containment lines and the fire was successfully burned overnight, which should bolster containment in that area, where crews are focused on preventing spread into residential areas.
No structures had been damaged or destroyed as of Sunday and no injuries were reported.
The Bay Area Air District issued an air quality advisory for the area, which it extended through Monday. The advisory is effective in portions of the counties of Solano, Napa and Sonoma.
Hot weather is forecast for the next few days, which Cal Fire said would create urgency to contain the fire, the cause of which was still under investigation as of Sunday.
More than 1,200 firefighters are on the ground fighting the flames, assisted by 140 engines, 10 helicopters, 20 hand crews, and 24 water tenders and 34 dozers.
