About 40 U.S. Forest Service firefighters were assigned Monday to the Grizzly Fire north of Libby, which an official said was estimated at 15 acres in size.

“The firefighters are working to improve access to get a fireline around the fire to get water to the fire,” Forest Service Public Affairs Officer Willie Sykes said via email. “(Sunday), high winds were a concern, but the fire hasn’t grown much. Weather will continue to be hot and dry, but not as windy in the coming days.”

The fire was reported about 7 p.m. Friday and is burning in timber, according to the Kootenai Interagency Dispatch Center website.

Sykes wrote that the Grizzly Fire is the Forest Service’s “main concern now, as other fires on the forest are either out, in patrol status or have resources on them.”
