This is generally a good time to get out and explore the backcountry.

Carefully evaluate steep lines for wind slabs before committing.

Moderate

Avalanche Summary

There have been no new reports of avalanches since Monday when explosive avalanche control produced several storm slabs up to size 2. Notably, these avalanches did not step down to the December persistent weak layer.

If you head out in the backcountry, let us know what you are seeing by submitting a MIN report!

Snowpack Summary

Isolated wind slabs may exist in the alpine due to redistribution of surface snow by west winds gusting into the moderate range. In sheltered areas, snow surfaces are faceting, preserving the good quality riding. On steep solar aspects, a thin melt-freeze crust covers the snow surface. Check this MIN from Norn for more details.

Down 50 to 120 cm weak layers of surface hoar or a facet/crust combo persist in the mid-snowpack. There has been no recent avalanche activity on this layer and snowpack tests indicate it is slowly gaining strength.

The lower snowpack is generally strong and well-bonded.

Weather Summary

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Carefully evaluate steep lines for wind slabs.
  • This is a good time for exploring terrain.

Avalanche Problems

Wind Slabs

Pockets of wind slab may exist in leeward terrain features in the alpine. They may remain reactive to riders on Thursday.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Possible
