In sintesi

The wind may just be stripping the snow, but if it's landing on the slope it's forming a wind slab. The best and safest riding will be on low-angle, sheltered slopes.

Avalanche Summary

No new avalanches have been reported since Wednesday, but it is suspected that there were some small wind slabs that failed on Saturday.

Snowpack Summary

Up to 10 cm of new snow from Saturday is being redistributed by westerly wind. Scouring the west side and forming wind slabs in leeward areas.

There is a melt-freeze crust near the base of the snowpack, but it generally appears to be stable and is not currently expected to be a problem for the region.

Treeline snow depths are typically 50 to 80 cm, with deeper wind-loaded pockets in the alpine.
