The Pondera County Sheriff's Office announced on Monday evening that the Strawberry Creek fire is expected to leave Forest Service boundaries by 10 p.m. on Monday.
In a Facebook post, the Sheriff's Office says that they will start pre-evacuation for residents located between Swift Dam to the Karl Rappold Ranch, and they are are making calls to those affected.
They said that due to the winds, firefighting aircraft can not fly at this time. When evacuations become mandatory, there will be a no-fly zone activated and this includes no drone flights. This is because of the type of aircraft that will be used to drop retardant and their flight pattern.
Road closures will be posted.
They ask that anyone who evacuates their property to tie a ribbon or colored twine on their fence posts to let responders know you have left the property.
The Strawberry Fire was reported on August 25th about two miles north of Sabido Cabin, between Strawberry Creek and East Fork Strawberry Creek, in the Bob Marshall Wilderness, on the Flathead National Forest.
The fire has burned about 4,913 acres as of Monday; it made a "significant wind-driven run" to the east on Sunday, and is currently up to the west side of Mount Richmond, about one mile from Swift Reservoir.
The fire is being managed with the Scalp and Crucifixion Fires by a Type 3 Incident Management Team based in Choteau.
