Avalanche Summary

No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Surface snow remains heavily wind-affected at higher elevations. A crust has likely developed on the surface with recent warm alpine temperatures.

The mid-pack contains several layers of note; a layer of surface hoar and a crust down 20 to 40 cm, a significant crust from the early December rain event down around 50 cm, and a second layer of surface hoar down 50 to 90 cm.

The base of the snowpack is generally facetted.

Weather Summary

Terrain and Travel Advice

  • Uncertainty is best managed through conservative terrain choices at this time.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Keep in mind that human triggering potential persists as natural avalanching tapers off.

Avalanche Problems

Persistent Slabs

A layer of surface hoar is down 50 to 90 cm and remains problematic where a significant crust is not found above it.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3
