An Avalanche Watch has been issued and the danger will increase into tomorrow.

Track new snowfall today and dial back your terrain choices as it gets deeper. Weak layers of surface hoar and faceted crusts are already buried under a foot of snow from previous storms. Storm slabs will become more sensitive this afternoon, especially in wind-drifted areas below ridgelines. Deeper instabilities lurk in the higher terrain. Downed logs and buried rocks will increase the consequences of triggering a slide.

Avoid steep slopes with fresh deposits of drifted snow, where you can trigger shallow slabs that can have large consequences. Be wary of large, open slopes with well-developed snowpacks, particularly close to the Continental Divide in Glacier National Park. On these slopes, the primary danger is triggering large slabs that break on old snow near the ground or a rain crust formed in mid November.

As winds increase from the east Tuesday evening, pockets of hard wind slab will form on exposed ridgelines and cross loaded slopes. The best riding will be found in sheltered terrain. Remember, a small ride early season can cause significant trauma as it pushes you through trees, rocks, and stumps.

As we move into Thanksgiving week, more snow and wind are being dished up for the Flathead region. Watch for new snow instabilities, specifically in wind drifted areas, and be wary of overhead hazards from deeper instabilities.

The risk of triggering an avalanche will rise during a winter-like storm Tuesday through Wednesday. The hazard will most likely be confined to higher elevation terrain with enough snow coverage to ski or ride. Track snow totals and watch for wind drifted slabs forming on leeward slopes. The early season snowpack is thin and runs out as you lose elevation. Avalanches can drag you over and into rocks, stumps, or other obstacles increasing the consequences of getting caught.

Avalanche hazards so far this season are generally localized to high elevation terrain with sufficient snow coverage to ski or ride.   With a thin early season snowpack, avalanches can produce harsh consequences if they drag you over rocks, cliffs, or stumps. Pay attention to snow amounts and watch for rain on snow to increase the threat of wet avalanches through Monday.

If there's enough snow to ride, there's a enough snow to slide.  Avalanche hazards so far this season are generally localized to high elevation terrain with smooth and continous snow coverage.   With a thin early season snowpack, slabs breaking in new or windblown snow can produce harsh consequences if they drag you over rocks, cliffs, or stumps.  Pay attention to new snow, windloading amounts, and underlying weak layers if you are traveling on steep, snow covered terrain.
