Recently formed thin wind slabs have become reactive at higher elevations. Otherwise the  main concern remains the basal weaknesses.

Snowpack Summary

5 to 10cm of new snow has fallen in the past 36hrs. Strong to extreme SW winds are redistributing this snow and thin wind slab formation is ongoing in the Alpine and open areas at Treeline. The Dec 13th rain crust remains dominant in the snowpack below 2200m. The November rain crust and facet combo remains a concern deeper in the snowpack.
