Points saillants

Avoid wind slabs, they are likely sitting over top of a weak layer or a firm sliding surface, and keep in mind the possibility of triggering deeper instabilities in steep, shallow areas.

Otherwise, seek out wind sheltered areas for good turns on those creamy facets and pray for more snow.

    Small pockets of wind slabs are present in lee features and sit above a weak layer of facets or surface hoar.

    This problem is low probability but high consequence as it would be releasing near the ground thus with a lot of destructive volume. Be extra cautious where snowpack goes from thick to thin areas.

Avalanche Summary

No new avalanches observed or reported in the region.

Snowpack Summary

Five to 15 cm sits above a weak layer of surface hoar and facets. This weak layer is more problematic in areas of wind loading. The midpack is dense and supportive. At the bottom of the snowpack, the weaker, more facetted layer above the ground creates a deep persistent slab.
