Summary
Confidence
Weather Forecast
Fairly consistent for the next few days. Steady, moderate alpine winds from the SW, no significant snow and steady temps (-10) for tomorrow.
Avalanche Summary
Nothing new
Snowpack Summary
4cm of new snow today. Strong alpine winds made short work of it and blew it into fresh winslabs on NE aspects. These slabs, when combined with other buried slabs and older surface slabs account for the windslab problem as a whole. The deeper crusts remain our chief concern. They are down 30-50cm and are touchy in the alpine.
Problems
Wind Slabs
Many areas have multiple layers of windslabs. Expect them to react within each other, and possibly step down to deeper layers.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Persistent Slabs
The crusts from November are widespread and of varying condition. Some areas have it intact, while others have faceted out and become touchy. So far alpine & N-NE aspects have been problematic.
Aspects: All aspects.
Elevations: Alpine, Treeline.
