Fire crews dispatched by the Susanville Interagency Fire Center responded to seven fires Wednesday afternoon and evening, including two blazes that grew to more than 100 acres each. All were sparked by lightning.
Crews have completed fire lines and stopped progression of all the fires, the largest of which were the Willow Fire, and R-1 Fire, both in Lassen County.
The Willow Fire, about 12 miles southeast of Fall River Mills, burned 106 acres. No structures were damaged or destroyed. The R-1 Fire, about six miles east of Termo, burned 130 acres and destroyed one unoccupied house and one outbuilding.
Crews will be working on both fires for several days, improving fire lines and mopping up hot spots.
Fire crews also responded to the R-2 Fire, also in the Termo area, holding it to 11 acres.
Weather forecasters are calling for chances of lightning again today. A red flag warning, signifying high fire danger because of wind and low relative humidity, is in effect today for Modoc County and high desert lands in northeast Washoe County.
Officials at the Susanville Interagency Fire Center said aircraft will be patrolling areas impacted by lightning, watching for smoldering lightning strikes that could erupt into flames as temperatures and winds pick up again later today.
Fire officials urged area residents and visitors to be careful with any outdoor use of fire.
