The Mart fire was nearly contained Monday afternoon, then a storm moved through the area around 3:30 a.m. and flared it up again. It pushed the fire in three different directions.
There is no estimate on possible containment of the Mart Fire at this time. The fire is burning in mainly grass and sagebrush.
The fire has now grown to at least 3,000 acres and it is still spreading due to erratic afternoon and evening winds.
Firefighters are attacking it from the ground and the air, there are four air tankers and three helicopters making drops. The Sierra Front has assigned a Type-II overhead team to help combat the blaze.
Crews are also working to protect homes off of Scotts Road near Roberts Canyon. A barn has already burned, but the owner says she was thankful it wasn't her home.
Precautionary evacuations were begun by Lassen County Sheriff in the Scotts Road and Epps Road areas south of Chilcoot.
The four other lightning caused fires, which began on Sunday, July 20, are in patrol and mop up status. One has been fully controlled.
