Watch for fresh, reactive wind slabs forming in lee terrain features at upper elevations.
Small amounts of new snow and wind are forming fresh wind slabs in lee terrain features. They may be especially reactive where they sit over a variety of weak grain types and/or hard surfaces.
No new avalanche observations since Thursday when a small (size 1) wind slab was triggered by a sledder in the alpine.
Small amounts of new snow falls over faceted and wind-affected surfaces. At upper elevations, west winds are redistributing the new snow into fresh wind slabs in leeward terrain features. Older, hard wind slabs sit over weak faceted crystals and a crust, 20 to 30 cm below the surface.
The mid and lower snowpack is generally well-bonded and strong.
