Here’s the morning update for the Thompson-Divide Complex fires, including the Granite, Sheep and Thompson fires.

The big news continues to be the Sheep Fire, which triggered an evacuation order for Essex a few days ago. The Essex evacuation order was subsequently lifted and U.S. Route 2 was reopened for traffic using pilot cars to keep things orderly. However, authorities are still edgy about Essex and warned residents to be ready to evacuate on short notice. The arrival of cooler, wetter weather has helped firefighters throughout the region.

Fire Complex Completed: 32%
Resources – Total Personnel: 298 Injuries: 1 Structures Lost: None
20-Person Hand Crews: 2 Type-1 and 3 Type-2, 1 Wildland Fire Management Module (8), 1 Helitack Crew (10)
Air Support: Helicopters (2 Type-1 & 2 Type-3), Engines: 11 Heavy Equipment: 9
Cause of Fires: All three active fires have been determined to be lightening caused.

The Thompson-Divide Complex consists of the Sheep and Granite Fires in the Flathead National Forest and the Thompson Fire in Glacier National Park.
