The Hog Fire has prompted mandatory evacuations in northern California west of Susanville. By Sunday night it had burned 5,800 acres of land protected by the Lassen National Forest and the state of California. At 3:30 a.m. July 20 the fire was about one mile west of a housing development on the west side of the William D. McIntosh Highway (A1) and five miles west of Susanville. It has spread approximately 5 miles to the east since it started and is on both sides of Highway 44. Steep terrain and spot fires ahead of the main fire are complicating efforts of firefighters.

Resources assigned Sunday night included 25 fire engines, 8 hand crews, 15 dozers, 15 water tenders, 4 helicopters, and 6 air tankers.

The Facebook page for the Lassen County Sheriff’s office has details on evacuations. Anyone without internet capabilities can get information by calling (530) 282-5714.

An update from CAL FIRE at 9:30 a.m. Monday stated that no structures had been damaged or destroyed.
