Recent fresh snow has likely been redistributed by strong winds, especially at upper elevations. Wind slabs may be reactive to human triggering, especially in lee terrain.
Summary
Confidence
Moderate - Due to the number of field observations.

Snowpack Summary
50-90 cm of snow has fallen over the past week. Strong winds have likely formed wind slabs throughout the region. Deeper and more sensitive wind deposits are likely to be found at higher elevations. The storm snow sits on a weak layer of surface hoar (feathery crystals) and facets (sugary snow) that formed during the dry spell in early December. Information is limited in this region about how well the new snow is bonding to this layer. Deeper in the snowpack, there are several crusts including an early season crust with facets near the bottom of the snowpack.
Problems
Wind Slabs
50-90 cm of recent new snow has likely been redistributed by strong winds in the region. Wind loaded slopes at higher elevations are the most suspect for human triggering.
Approach steep lee and cross-loaded slopes with caution.Be alert to conditions that change with elevation, aspect, and exposure to wind.Field observations have been limited. Supplement this forecast with your own observations.
