    New wind slabs have likely formed above 2000 m from recent snow and strong southwest wind. This new snow may remain touchy to human traffic on Saturday, particularly in lee terrain features near ridges.

    Clear skies on Saturday could cause the new snow above 2000 m to moisten on sun-exposed slopes, increasing the likelihood of triggering loose wet avalanches.

If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!

Snowpack Summary

Around 10 to 20 cm of recent snow has likely accumulated above 2000 m. The snow fell with strong southwest wind, likely forming new wind slabs and cornice growth in the alpine. The snowpack below treeline is saturated and rapidly melting.
