This interface is still in forecasters minds at the base of the snowpack. In many areas, this crust is beginning to facet out.

Warm temperatures continue and winds are forecast to increase as we move into the weekend. We aren't expecting any new snow over the next 24hrs but there will be a pulse on Friday that may give us 5 cm or so.
Avalanche Summary
No new avalanche observations.
Snowpack Summary
Very little change out there at this time. Open alpine terrain is wind affects even areas down into treeline are showing evidence of wind affected snow surface. The dec 13th crust is being found up to 2200m down 30-50cm and is continuing to produce moderate sheers on a layer of FC both above and below this layer. Deeper in the snowpack the Nov 6th crust persist but is showing signs of breaking down. A new layer of surface hoar is widespread in all areas below treeline and sheltered areas in the Alpine that will likely be a problem when the next storm, or a storm, arrives.
