Snowpack Summary

Small amounts of new snow and continuous moderate to strong south west winds have been ongoing for the past week. Alpine and tree-line areas are slowly gaining enough snow for avalanches, particularly in leeward alpine bowls, gullies, and around ridge lines.

Avalanche Summary

There have been isolated reports of smaller wind slabs in alpine features over the past week, but not a lot of people are out in the mountains so take that into account in your decision making.
