Points saillants

With a snowpack like this, there's no excuse to not have your holiday shopping wrapped up by Sunday. There may be good skiing out there in very sheltered areas, but expect a thin and largely unsupportive snowpack.

Problèmes avalancheux

    • Sous la limite forestière

    Possible - Likely

    1–2

    Windslabs are common in alpine areas. Watch for this areas around the "lens" of windslabs where it will be more likely to trigger this weakness. Any failure will likely step down and involve the entire winters snowpack.

    If triggered the surface wind slabs may step down to this layer and involve the entire winters snowpack.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Lots of wind slabs out there in the alpine and treeline. Most are limited to crossloaded gullies and immediate lee areas, however there are some areas at treeline that have seen more widespread wind loading (Tent Ridge for example). You can also expect to find laminated, multi layer wind slabs. A real potpourri of wind slab out there. The Dec crust is out there, but hasn't had enough load to be an issue yet. And lastly, who can forget the Oct crust? Yes, this is still there and perhaps our biggest concern. It is still a layer to be concerned with, especially in thin snowpack areas.

Weather Summary

Wish there was better news...

No significant snow for tomorrow. In fact there's no snow forecast for the next few days. Crickets out there. Temperatures are mild with overnight lows around -10, and high of -6 for tomorrow. Winds will gently blow out of the south west.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Avoid steep terrain that is rocky and thin.
