Firefighters made gains Monday on all areas of the Shirley Fire, bringing the containment to 50 percent, said Tom Efird, a battalion chief with the Garden Valley Fire Protection District.
Efird said for the first time since the start of the incident the fire did not burn actively in the afternoon.
A wind advisory has been issued for the Kern Valley and will remain in place until Tuesday afternoon.
Helicopters capable of night operations will remain available to firefighters on the ground tonight in case the fire escapes the perimeter.
All evacuations have been lifted, but due to continued firefighting and suppression activities, portions of Old State Road will be closed to all but local traffic. Residents are asked to exercise caution when driving in the area.
Portions of Rancheria Road, Wagy Flat Road, Sawmill Road, and Alder Creek Road are still closed. Highway 155 is closed at the intersection of Wofford Heights Boulevard.
Just over 2,600 acres are still burning. A total of 1,681 personnel are working the Shirley Fire, and it so far is costing $6.2 million.
