Snowpack Summary

Alpine winds have now created firm windslabs on Northeast to South aspects. They tend to be more pronounced in the northern part of the region. At treeline, the windslabs are widespread and are reaching far below ridge crests. The warmer temperatures have also contributed to settlement within the snowpack. The depth of buried weak layers will likely have changed significantly with the redistribution of snow.
