The Hat Fire was first reported about 2:38 p.m. near the Hat Creek gun range west of Fall River Mills. The fire quickly grew to 700 acres due to sporadic winds from the northwest. The fire burned on both sides of Highway 299 resulting in the highway closed at Cassel Road on the west and at Glenburn Road on the east. Air tankers from Redding were reportedly grounded due to the heavy smoke from the 17-day-old Carr Fire. Two tankers were reportedly deployed from Chico and a 747 was flying in from Sacramento. Electricity was out in Burney, Cassel and Fall River Mills beginning at 6:02 p.m. with no estimate of when power would be restored as PG&E crews are unable to access the affected equipment. Mandatory evacuations were ordered for the BLM campground near the Pit River, Clearwater House, the Glenburn area and the west side of Fall River Mills.
