Points saillants

If you are willing to work for the turns there is good skiing to be found in above 2100m. Getting there is the challenge though as the crusts can make travel difficult.

    The basal november rain crust has produced some large avalanches during last weeks storm event. Be thinking about thin weak areas as you travel. 

Terrain and Travel

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Approach lee and cross-loaded slopes with caution.

Confidence

Moderate -

Weather Forecast

Light snow is forecast to move into the region overnight and into Wednesday with total accumulations around 5-7cm. Temperatures are forecast for a daytime high around -8C. Winds are going to be into the moderate range but more out of the north.  

Avalanche Summary

No new avalanches have been observed over the past 24hrs.  

Snowpack Summary

Not much is changing out there right now. Windslabs can be found in the upper snowpack in the alpine along ridgelines and in lee features. Deeper in the snowpack is November 5th facets/crust interface. Generally this layer is at or near the ground and harder to trigger, but it has produced a few large avalanches over the past few weeks. Think about thin snowpack features as you travel. Below 2150m the rain from earlier this season has solidified the snowpack. This will be good long term but at this moment, it makes travel challenging and hard.
