Avalanche Summary

No new avalanches were reported in this region on Saturday.

If you head into the backcountry, consider posting to the mountain information network.

Snowpack Summary

10-25 cm of recent snow and forecast moderate northwest wind may form new wind slabs on generally windward aspects. The recent snow overlies a widespread crust.

Various weak layers persist in the mid to lower snowpack, however, triggering these layers is unlikely where they are capped by a thick crust.

Areas in the east of the region are largely characterized by a shallow and faceted snowpack.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
