Highlights

Good skiing can be found in sheltered places.  Wind slabs are still a concern for human triggering in the alpine.

Avalanche Summary

No observations were made today.

Snowpack Summary

In general, the upper half of the snowpack is not showing any weaknesses and is bonding well. The exception is in the alpine where the wind slabs are 20-40cm thick and are still possible to trigger. The biggest concern is for the December 15 facets which is showing a lower probability of triggering but with a high consequence if an avalanche occurs. Be careful of thinner areas where triggering the deeper layer is more likely.  The sun is starting to have some punch to it, so be aware of steep solar aspects. .
