Points saillants

North wind may form small wind slabs on aspects that are typically windward.

Watch for small wind-loaded pockets especially around ridgecrest and in extreme terrain.

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. Widespread surface hoar has formed on all aspects at all elevations and a sun crust may exist on solar aspects.

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.
