Small pockets of wind slabs from new snow and strong southesterly winds are present in lee features. These sit above a weak layer of facets or surface hoar.
Small wind slabs from recent wind and snow exist above treeline and the deep persistent problem remains a low‑likelihood but high‑consequence concern.
Skiing is generally rugged, but sheltered slopes with surface faceting offer decent turns. Otherwise, it’s a good time for mountain walks.

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.
No new avalanches observed or reported in the region.
Five to 10 cm of new snow 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 in most areas. At the bottom of the snowpack, the weaker, more facetted layer above the ground creates a deep persistent slab.
