AN AVALANCHE WATCH IS IN EFFECT until Wednesday at noon.  

Dangerous avalanche conditions exist in the Whitefish Range, Flathead Range and Glacier National Park. Heavy snowfall and gusty winds have overloaded a fragile snowpack. Natural and human-triggered avalanches remain very likely. Fresh avalanches, whumpfing sounds, and shooting cracks are sure signs of danger. Avoid traveling on or below steep slopes at mid and upper elevations.

Ch-ch-changes. The avalanche danger is rising as new and drifted snow accumulates.  Today you can trigger small avalanches on steep slopes, mostly near ridgelines. Step back and reconsider if you see shooting cracks or feel collapses near steep, open slopes at any elevation. With heavy snow and gusty winds forecast for tonight, dangerous conditions are likely to develop overnight.

Increasing winds will form shallow slabs at upper elevations. Evaluate wind loaded terrain below ridgelines and in gulleys.  Generally stable conditions are found on wind protected slopes. Sluffing remains possible in very steep terrain. Early season obstacles can increase the consequences of an avalanche.  

Recent winds have formed thin isolated slabs at upper elevations. Evaluate wind loaded terrain below ridgelines and in gulleys.  Expect generally stable conditions on wind protected slopes. Sluffing is possible in very steep terrain. Early season obstacles can increase the consequences of an avalanche.

Increasing winds will form thin slabs on Wednesday that could remain sensitive to human triggers for several days.  At upper elevations, evaluate recently wind loaded terrain below ridgelines and in gulleys.  Generally stable conditions are found elsewhere, apart for shallow sluffing. Early season obstacles can increase the consequences of an avalanche.  

Light snow Friday night will increase the risk of loose dry avalanches where the most snow accumulates.  Monitor new snow totals as you travel.  Early season obstacles can increase the consequences of an avalanche.  Below about 6,000' the snow cover is generally too thin for avalanche concerns.

A series of storms will bring increasing avalanche hazard to high elevations into the holiday weekend.  Pay attention to local storm totals and be cautious of wind loaded slopes: newly formed slabs will not bond well to existing snow coverage.  Early season obstacles can increase the consequences of an avalanche.  The snowpack remains generally too shallow on low elevation or brushy slopes for avalanche concerns.

New snow and increasing winds on Friday may create persisting instabilities on higher elevation, wind drifted terrain.  Early season obstacles can increase the consequences of an avalanche.  The snowpack remains generally too shallow on most mid and lower elevation slopes for avalanche concerns.

An increase in wind speeds accompanied by new snow will form shallow instabilities on high elevation, wind drifted slopes through the weekend.  Beware of thin snow coverage and buried obstacles to amplify the consequences of an avalanche.  The snowpack is generally too shallow on most mid and lower elevation terrain for avalanche concerns.

Continued precipitation, warming temperatures, and gusty winds leading into this weekend will cause increasing avalanche danger on high elevation, snow-covered slopes.  Watch for changing conditions and be wary of natural avalanches.
