The County fire grew to 72,500 acres by day’s end on Tuesday, with containment up to 15 percent and no damage to the 980 structures in the fire’s path, Cal Fire said.
On Tuesday the resources assigned to the County fire increased notably, with hundreds more firefighters and nearly 100 more engines arriving to assist.
By day’s end, Cal Fire said there were 2,665 firefighters, 274 engines, 56 water tenders, 18 helicopters, 55 hand crews and 67 dozers.
Cal Fire said firefighters worked aggressively through the day Tuesday to build containment lines
around the County fire.
Those efforts, Cal Fire said, have been hampered on the northern end of the fire by steep, inaccessible terrain.
At the same time, cooler temperatures are expected through Wednesday, but winds and dry vegetation still have the potential to fuel fire growth, Cal Fire said.
The changing conditions led to the announcement of some evacuation orders being lifted and new ones being implemented.
On Tuesday night, the Yolo County Sheriff’s Office said it changed certain evacuation orders from mandatory to advisory due to containment lines and better weather conditions.
Impacted areas include those west of State Highway 16, between County Road 76 and County Road 81, including the community of Brooks and the Yocha Dehe Wintun Nation; west of County Road 89, to the burn area, from County Road 23 in the North, to State Highway 128 in the South.
Those areas don’t include the previously evacuated areas of Napa County, north of State Highway 128 between the eastern shore of Lake Berryessa and the Napa/Yolo County Line.
The road closure along State Highway 128 between Pleasants Valley Road and Markley Cove Resort remains in effect. Residents along Positas Road will be allowed access with valid identification, officials said.
Less than an hour after that announcement was made, the sheriff’s offices for Yolo and Napa counties said they had issued a mandatory evacuation for the area west of State Highway 16, to Berryessa Knoxville Road, south of Old County Road 40 and north of County Road 53.
Residents of the Yolo County portion of that area were urged to evacuate immediately.
The Napa County evacuation area does not include any permanent residences, with deputies surveying the evacuation area for campers.
In other fire-related news, the California Department of Fish and Wildlife said Tuesday night that the Knoxville Wildlife Area located in northeastern Napa County is closed until further notice because of the County fire.
The Knoxville-Berryessa Road, which runs through the wildlife area, is currently closed. Due to the uncertain nature of the fire it is unknown when the wildlife area will reopen, officials said.
