    The basal layers are very weak. An avalanche initiated in the upper snowpack could step down to the bottom of the snowpack.

Confidence

Moderate - Timing of incoming weather systems is uncertain on Sunday

Weather Forecast

As the cold front pushes throuhgou the region tonight we can expect a few more cm of snow to fall.  At most 10cm is what we should expect.  Winds will continue to be the dominate theme overnight before easing tomorrow as temperatures return to more seasonal values. 

Avalanche Summary

A few new sz 1-2 slabs at treeline and low alpine areas. These slabs were mainly on N, W and E aspects and failing in the basal facets.

Snowpack Summary

8cm new in the Alpine over the past 24hrs and a few cm throuhgout the day but overall, wind was the main theme. Strong winds from the west pummelled the snowpack creating widespread hard slabs in open areas. The Dec 10th and the weak layer of facets underneath this layer are the main culprits these days as any failures in the snowpack are going to involve the weak basal facets and the majority of the snowpack. Ski quality is pretty dismal for sure.
