Points saillants

Carefully evaluate steeper terrain for wind slabs, as there is potential for avalanches to step down to deeper weak layers.

    Expect stiffer and deeper deposits of snow on northeast and southeast facing slopes. Watch for steep convex rollovers, ridgetop entrances, and cross-loaded features.

    A widespread crust with facets is buried 50 to 100 cm deep. Wind slabs may step down to this layer, producing large avalanches.

Avalanche Summary

No new avalanche activity has been reported since last weekend.

Several natural and rider-triggered avalanches, up to size 2.5, were reported on the 18th and 19th of January. A number of these reports occurred on the weak layer from early December.

Snowpack Summary

Recent snow has been heavily wind-affected in exposed areas. A crust exists below 1250 m, making for challenging travel conditions.

A weak layer of facets and a crust from early December is buried roughly 50 to 100 cm deep.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
