Early Season Snowpack Update:  Fresh snow and gusty northeasterly winds have created storm instabilities on windloaded and shaded aspects, especially at high elevations.  Avalanches will be sensitive to human triggers, and an early season slide will result in an unpleasant ride given our thin snow coverage.  Cracking snow and deeper drifts are signs to avoid steep terrain. Be prepared for avalanche hazards this weekend.  

The FAC will monitor conditions through the fall and post updates as the snowpack evolves.

Fall Advisory Statement:  Shallow, early season snow coverage exists above 6,000 ft.  Avalanche concerns are minimal under our current conditions, but you are most likely to find lurking instabilities on terrain features holding deep enough snow to cover rocks and vegetation - generally wind-loaded features.  If you are traveling in the alpine, carry avalanche gear and be mindful of terrain consequences.  The FAC will monitor conditions through the fall and post updates as the snowpack evolves.

Fall Advisory Statement:  A series of increasingly powerful systems will bring snow and wind to high elevations through the weekend.  Watch for changing conditions and isolated instabilities developing on wind-loaded slopes above treeline.  Exposed rocks and cliffs will amplify the consequences of an avalanche. Identify and avoid thicker deposits of wind-drifted snow.  The FAC will monitor conditions through the fall and post updates as the snowpack evolves.

Fall Advisory Statement:  Avalanche accidents can happen long before the chairlifts start spinning.  Recent snow accompanied by gusty winds has increased the threat of sensitive wind slabs at higher elevations.  Be wary of fresh wind drifts below ridgelines or in cross-loaded gullies.  Even a small avalanche can have severe consequences if you get dragged into rocks or through vegetation.   The FAC will monitor conditions through the fall and post updates as the snowpack evolves.

Fall Advisory Statement:  Avalanche accidents can happen long before the chairlifts start spinning.  If you are traveling on high elevation, snow-covered slopes, be mindful of isolated instabilities.  The consequences of a small avalanche this time of year are amplified by rocks, trees, or cliffs.  Be wary of windloaded or deeper snow in alpine terrain, especially where it has accumulated over old snow or ice layers.  The FAC will monitor conditions through the fall and post updates as the snowpack evolves.

Spring Avalanche Statement -Spring in northwest Montana brings a mixed bag of weather. Snow, rain, sun, and everything in between can occur all in one day. This can greatly affect avalanche conditions. It is essential to pay attention to changing conditions as these changes can happen rapidly and stability can also deteriorate fairly quickly. Avalanches still happen in the spring and it is important to not let your guard down.

Special Advisory Statement: Significant amounts of new snow combined with a warming trend will create dangerous avalanche conditions into the weekend, especially on Saturday.  Natural loose wet avalanches will become likely under rising freezing levels and direct sunshine (see video).  With snowfall in excess of 20" in higher terrain, these slides can entrain dangerously large volumes. Watch for rapidly changing conditions and be mindful of overhead hazards if you are traveling in the mountains this weekend.
