Snowpack Summary

The storm snow has settled into a dense slab that can be triggered by skiers or sledders that is propagating up to size 2.0 avalanches. There has been a lot of wind transport and wind slab formation in the alpine. Professionals are finding the early January surface hoar layer to be well preserved in more locations below 2000 metres than had been suspected.
