Early Season Snowpack Update: Another round of snowfall and wind will be impacting our region over the next 4 to 5 days. Going into the weekend, backcountry travelers should pay attention to storm totals and be wary of freshly windloaded slopes. An early season avalanche could result in an unpleasant ride over numerous obstacles due to shallow snow coverage.  

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

Early Season Snowpack Update: Expect changing avalanche hazards over the next 48 hours with the arrival of new snow and strong southwest winds.  Cracking snow in windloaded terrain is a sign of instability indicating avalanches will be sensitive to human triggers, with an unpleasant ride giving way to potentially high consequences.

Early Season Snowpack Update: New snow on Thursday and Friday accompanied by increasing southwest winds will form fresh wind slabs on high elevation, leeward aspects.  Thicker drifts, shooting cracks, or drifting snow are signs to be wary of steep, wlndloaded terrain.   Early season obstacles are prevalent, and a small avalanche could result in a harsh ride over rocks and vegetation.

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.

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.
