Avalanche Summary

No recent avalanche activity has been reported.

We anticipate natural avalanche activity to increase with forecast heavy precipitation and strong winds.

Snowpack Summary

New snow has buried a widespread crust on all south-facing and below-treeline terrain. Weak facets or surface hoar may exist just below the new snow in sheltered north-facing terrain features.

Various weak layers, including crusts, facets, and/or surface hoar exist approximately 50 to 100 cm below the surface. An additional crust and facet layer may be found 100 to 150+ cm below the surface. These layers are trending into dormancy, however, lingering concern remains for human-triggering these persistent weak layers.

Terrain and Travel Advice

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Keep in mind the crust offers an excellent bed surface for avalanches.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
