Just 17 percent of the massive County fire in Yolo and Napa counties remained uncontained Tuesday and fire crews pushed on efforts to button up the northern portion of the 90,288-acre fire.

Weather conditions Tuesday included possible triple-digit highs, low humidity and breezes. “We’re still not completely out of the woods yet. We’re still apprehensive,” Cal Fire Capt. Dan Olson said.

Firefighters were aggressively working to extinguish areas still burning within the 140‑square‑mile fire scar, said Olson.

While the fire was nearly contained, the most northern section still doesn’t have a strong containment line.

Crews set off a control burn in the area Monday to remove fuel in its path.

The fire started June 30 near the Yolo County rural community of Quinda, on Highway 16. Winds pushed it south, burning down into Napa County near Lake Berryessa.

It is the largest fire currently burning in California.

Residents of Lake County’s Spring Valley got another scare Monday afternoon when fire broke out, burning 80 acres. It was 80 percent contained as of Tuesday, Cal Fire said.

The fire burned into land just scorched by the recent Pawnee fire, which is 100 percent contained. No evacuations were ordered from the new fire.

“This community has been very fire weary the last 4 to 5 years,” Olson said.
