A Red Flag Warning has been issued for Saturday from noon to 8 p.m. for gusty winds and low humidity. The fires may see wind gusts in excess of 40 mph on ridge tops. Wind direction will start from the south and southeast, then come from the southwest and west with passage of a cold front. These conditions could cause active fire behavior including short crown runs and spotting up to ½ mile on all three fires in the complex. Weather conditions will be changing this weekend. A cold front is predicted to arrive late Saturday afternoon. Humidity will increase with a slight chance of showers and thunderstorms as this front passes through the area. On Sunday, temperatures will drop about 10 degrees and humidity increase. A chance for showers will remain.

Sheep Fire, Flathead National Forest

Structures At Risk: 200+ structures, BNSF has several wooden snowsheds and 1 trestle, utilities infrastructure

Approximate Size: 1,595 acres Containment: 0% Structures Lost: None

Fire Update: The Sheep Fire is on the Flathead National Forest and burning in very steep terrain with limited access. The fire is about 1 mile south of Essex and about 1/8 mile from the train tracks between Tank Creek and MacDonald Creek. The fire has not crossed Sheep Creek to the south. Today, fire behavior will depend on the influence of the approaching cold front and the persistence of smoke over the fire. Construction of the shaded fuel break around Essex is nearing completion. Today’s focus will be on the removal of the remaining logs and slash that was created and any cleanup of the fuel break. The objective of this fuel break is to reduce the fuel component and space the tree crowns to limit fire spread and torching. It will also provide a safe location for firefighters if it is decided to burn out fuels in advance of the fire front. Helicopters will be used to drop water on the fire to reduce fire spread as long as visibility requirements can be met. Structural protection in Essex will continue. Night shift continues to monitor fire movement and patrol the Essex area and Walton compound for any encroaching fire activity.

Granite Fire, Flathead National Forest

Approximate Size: 701 acres Containment: 0%

Fire Update: The Granite Fire is burning in very steep terrain in a mixed conifer forest. The fire is located west of Marias Pass and south of Hwy. 2. The fire started in the Great Bear Wilderness and has moved north out of the Wilderness. Yesterday, the fire moved to the west along a ridge between 2 unnamed tributaries of Granite Creek and northwest toward Patrol Ridge. A crew was flown into the Granite Cabin to put in structure protection measures, including wrapping and sprinkler placement. Crews have implemented structural protection measures on other facilities in the fire’s vicinity. Crews have established locations for fireline construction and possible shaded fuel break opportunities when sufficient crews become available for their construction. Helicopter bucket drops are being used to help check fire spread.

Thompson Fire, Glacier National Park

Approximate Size: 17,857 acres Containment: 20%

Structures At Risk: 2 historic cabins Structures Lost: None

Fire Update: The Thompson Fire is located in remote south-central backcountry of Glacier National Park about 15 miles east of the West Glacier entrance in the Thompson and Nyack drainages west of the Continental Divide. All fire personnel have been removed from this fire. It will be monitored from the air for any increased fire activity. Pumps and hose lays are in place in case a future need arises.

Most of Glacier National Park is unaffected by this wildfire complex and is available for recreational use. Limited backcountry closures are in place. For more specific visitor information, please see the website

The Thompson Fire has not impacted park roads. The Going-to-the-Sun Road is open.
