In sintesi

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

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    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.

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, buried in early December, of facets and a crust is down roughly 50 to 100 cm from the surface.

Avalanche Summary

No new avalanche activity has been reported since the weekend.

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

Confidence

Moderate

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.
