    Fresh snow may form unstable wind slabs on northerly terrain features. They may bond poorly to the underlying crust.

Confidence

High

Avalanche Summary

No recent avalanches have been reported in the region.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!

Snowpack Summary

10 to 20 cm of new snow will accumulate above a thick crust with some deeper wind deposits possible at higher elevations.

The snowpack below the crust is dense and bonded.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
