An estimated gain of 100 acres was reported at the Chrandal Forest Fire Saturday.

The fire, on the Montana-Idaho border at the south end of the Bitterroot National Forest, was slow-moving Saturday with cooler temperatures in the area. The fire is about 40 miles south of Darby.

Though storms passed through the region, officials report that there was little significant rain on the fire.

There were incidents of individual trees "torching" inside the fire perimeter Saturday (See photo). Sunday, crews will be working on firelines on the southwest section of the blaze.

Almost 300 people are on the fire, with a "full suppression" management plan. However, the rugged terrain and a large amount of snags and beetle-killed trees are posing safety hazards preventing opportunities for direct attack.

The crews were working on spot fires that have spread to the south of the main fire into Idaho. Also, structure protection is being prepared in the upper Hughes Creek Road area where about 16 homes are threatened.

Traffic on all of Hughes Creek Road is now limited to local residents only and fire traffic. The Ravalli County Sheriff's Office has put a number of homes on Stage I Evacuation Alert.

Fire managers expect some growth to the north and east with winds and weather being the determining factor.
