NAPA COUNTY, Calif. (KGO) -- The County Fire burning near Lake Berryessa has grown to 86,000 acres in the rough, mountainous terrain of Yolo and Lake counties and is threatening nearly 1,000 structures. So far, the fire is 30 percent contained.
The Yolo County Sheriff just ordered additional mandatory evacuations and road closures. The evacuation order applies to the area west of State Highway 16 to the Yolo-Lake County line, north of County Road 40 and south of the Yolo County line. State Highway 16 has been closed between State Highway 20 and Rumsey Hall.

Over 2,800 firefighters are still battling the blaze that nearly doubled in size on Monday.
"The fire laid down, last night," said Cal Fire spokesman Israel Pinzon. Crews worked all night building containment lines along the fire.
At least 2,500 people have been told to evacuate as the so-called County Fire continues to spread, said Anthony Brown, a spokesman with the California Department of Forestry and Fire Protection.

Brown said the blaze started Saturday and is surging through rugged terrain northwest of Sacramento amid hot and dry weather. "The weather is better than what we had last weekend. But it's still hampering our efforts and it's an area of concern," he said.
So far this year, wildfires have burned 4,200 square miles in the United States, according to the fire center. That's a bit below last year's acreage to date - which included the beginning of California's devastating fire season - but above the 10-year average of 3,600 square miles.
Cal Fire officials say their goal is to have full containment of this fire by next Tuesday, July 10, 2018.
