Avalanche Summary

No new avalanches were reported in this region on Sunday.

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

Snowpack Summary

In areas that still have snow available for transport, strong north wind may form small wind slabs on aspects that are typically windward.

10 to 25 cm of snow overlies a widespread thick crust that exists at all elevations.

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

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
