Rain at low elevations, and heavy snow in the alpine is rapidly adding load to the snowpack. The upper snowpack was already moist from warm temps and is expected to be easily triggered by light loads. Be cautious until freezing levels lower.

Snowpack Summary

Avalanche Summary
Yesterday, moderate S'ly winds loaded lee aspects and triggered size 2 avalanches from paths with steep N facing start zones. On N aspects in the alpine, stubborn windslabs were reported to be reactive to skiers producing size 1 avalanches. At low elevations, loose wet avalanches were observed this morning up to size 2.
