Fire crews say a grass fire burning 33 miles east of Missoula is threatening several homes in the Felan Gulch area.
The fire was first reported as a spot fire a little before 1 p.m. Thursday in Bearmouth Gulch, on DNRC land. Since then it's blown up to more than 60 acres.
The fire is burning up a southeast-facing hill in grass, and is being driven by wind.
Fire officials said they diverted air resources off the Elevation Mountain fire to respond to Bearmouth Gulch.
We have a reporter on scene who says there are multiple helicopters making water drops.
The Granite County Sheriff's Department is responding, no word yet on any evacuation plan.
Fire officials issued a red-flag warning across most of the state for Thursday and Friday.
Officials are asking everyone to be extremely cautious. They say something as simple as driving through dry grass, or flicking a cigarette out the window right now could start a wildfire.
