By 7:30 p.m. the fire had burned 67 acres, but crews were able to bring containment to 50 percent.

A total of 24 engines, seven water tenders and four hand crews are currently battling the fire. Cal Fire said that the fire is burning in grassy oak woodlands in steep terrain that have made fighting it a challenge.

While crews have made good progress, they are expected to remain on the scene overnight building containment lines and extinguishing hot spots.

No structures are currently threatened.

Air crews have been brought in to battle the blaze.

The Pope Fire has erupted near the burn zone of the Glass Fire, a blaze that roared through 67,484 acres in Sonoma and Napa counties, destroying 642 homes and laying to waste 365 commercial buildings, including nearly two dozen wineries.

Cal Fire officials announced 100 percent containment of the Glass Fire Tuesday, more than three weeks after it started.

The fire is also burning near an area burned by the massive and deadly LNU Lightning Complex fires that burned earlier this summer. The complex, sparked by an unusual lightning storm in August, killed five people, burned 363,220 acres and destroyed nearly 1,500 structures. It was one of the largest wildfires in California history, and was not fully contained until early October.

Friday’s fire comes as the wildfire-region braces for the possibility of even more wildfires, as winds are expected to pick up early next week. The National Weather Service has issued multiple Red Flag Warnings for the Bay Area, including a warning impacting the North Bay mountains from 11 a.m. Sunday through 11 a.m. Tuesday.

Cal Fire officials said Chiles Pope Valley Road is closed from Pope Canyon Road and Lower Chiles Valley Road as of Friday evening.
