Snowpack Summary

5-10 cm of storm snow has been redistributed by Moderate - Strong SW winds. This has created fresh windslabs which sit over a melt freeze crust on all but North aspects. The mid pack is strong and well settled. Basal instabilities haven't been seen in some time, but are likely lurking in thin areas.

Avalanche Summary

Avalanche activity in the last week has mainly been limited to loose wet avalanches up to size 1 on solar aspects with daytime warming.
