Snowpack Summary

25 cm of new snow at Parkers ridge in the past 24 hours with moderate to strong south west winds. Alpine and tree-line areas are slowly gaining enough snow for avalanches, particularly in leeward alpine bowls, gullies, and around ridge lines.

Avalanche Summary

No new avalanches have been observed by the road patrol on Saturday. There have been reports of smaller isolated 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.
