ADIN, Calif. (AP) — Firefighters gained ground on a large wildfire in rural northeastern California, but weather was expected to become less favorable.

The 34-square-mile (88.3-square-kilometer) Gold Fire in northern Lassen County was 60% contained Monday night after a few thunderstorms during the day, the California Department of Forestry and Fire Protection Said.

Weather, however, was expected to transition Tuesday to a drier air mass before the area south of the small Modoc County community of Adin begins to be impacted by low humidity and gusty winds.

The fire has been burning since July 20 in an area of private homes, ranches and commercial operations.

Three areas remain under evacuation orders and evacuation warnings are in effect for a wider area.

In southern Lassen County, the nearly 15-square-mile (38.5-square-kilometer) Hog Fire west of Susanville was 64% contained.

Logging slash and heavy fuels continue to burn and smolder within the perimeter, and authorities said warm and breezy conditions could increase the risk of fire activity, but all evacuation orders have been lifted. The fire began on July 18.
