Thompson-Divide Complex morning update – Sep 3, 8:00 am

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 (see map below), 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.

Seems like the Sheep Fire should have a scarier name, doesn’t it?

Resources – Total Personnel: 262, Injuries: 1 Structures Lost: None

20-Person Hand Crews: 2 Type-1 and 2 Type-2 Air Support: Helicopters (2 Type-1 & 2 Type-3), Engines: 8

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