HELENA, Mont. — Hot, dry weather isn’t helping firefighters battling wildfires throughout Montana.

The Lolo National Forest in western Montana is the scene of several large fires that are being suppressed.

The largest fire has burned about 8.6 square miles (22.2 square kilometers) about 12 miles (19.3 kilometers) southeast of Superior in Mineral County. About 40 homes and cabins have been evacuated and others are threatened.

The fire was started by lightning on July 16.

The number of firefighters battling the fire has increased to over 500 with the help of four helicopters. Containment has been stuck on 5 percent for the last few days.

Firefighters continue to battle other fires, including in the Beaverhead, Deer Lodge, Bitterroot, Helena and Lewis and Clark national forests, and near Roundup north of Billings.
