    Watch for pockets of cohesive wind slabs on the lee side of ridges or ribs. However, with the sugary-faceted-weak snowpack avalanches could step down to the middle of the snowpack.

Avalanche Summary

No new avalanche reports. Keep sharing your observations via the MIN; it helps strengthen our information gathering.

Snowpack Summary

In deeper zones at 1900 m the snowpack is around 100-130 cm, which is low for middle of December, and it has a weak structure.

Surface: Boot top powder in deep areas. Same old crusts, facets, and rocks on wind scoured slopes.Upper-pack: Below the fresh snow is well developed surface hoar in sheltered areas. The uppper part of the snow pack is generally low density and faceting (aka weak).Mid-pack: maybe a crust or two, with a layer of soft facets above. This is likely the primary weak layer.Lower-pack: facets and depth hoar (aka not strong).

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Expect shallow snow cover that barely covers ground roughness.
