All evacuation orders have been lifted for the Ridge Fire and roads are back open, the Colusa County Sheriff's Office said on Friday. Previous coverage below: Crews have made progress against the fast-burning brush fire near the border of Lake and Colusa counties that prompted nearby evacuations and threatened nearby structures, officials said.The fire is burning near Walker Ridge Road and Highway 20 near the Lake-Colusa county border. As of Monday at 6:10 p.m., Cal Fire said the fire had burned 2,756 acres, a slight increase from 2,600 acres reported earlier in the day. Containment had grown to 30%, up from 25% on Monday. Containment is measured in percentages to describe a break or line where combustible material around the fire has been achieved, helping prevent the fire from spreading further.Cal Fire Sonoma-Lake-Napa Public Information Officer Jason Clay said it was a wind-driven fire that initially spread quickly when it started at 4:30 p.m. Saturday. He described the challenges."On that North side in particular is some steep and rugged terrain, so getting the resources that we need right in there," he said. "We have a lot of bulldozers doing that and we have a lot of helicopters helping out with a lot of water drops and then our hand crews."Clay said they need a combination of all resources to keep the fire in a boxed area. He said it's an area that's burned in the past, so there is not a lot of established forest and a lot of brush and grass are burning.He also said it's a remote area with ranches and cabins. Cal Fire said about 30 structures in Lake County are threatened by the fire. Twenty in Colusa County are also threatened.Some of the threatened structures are at the Wilbur Hot Springs resort. Crews were able to create a fire line up the ridge behind the resort to keep the flames from spreading to the buildings on the property. No structures have been reported damaged. The Colusa County Sheriff's Office issued evacuation orders for parts of Colusa and Lake counties. In Colusa County, only Wilbur Springs and Wilbur Springs Road remain under evacuation orders and road closures. You are lawfully required to leave immediately when evacuation orders are issued because of the threat to safety.There were also evacuation warnings in place in Lake County but they were lifted Thursday. You are not required to evacuate under warnings but are recommended to do so in case conditions become dangerous. Highway 20, east of Clearlake Oaks at Route 53, has fully reopened after being shut down due to the fire.Meteorologist Dirk Verdoorn said winds helped drive the fire, with gusts as high as 29 mph recorded.
