Recently formed wind slabs may remain reactive at higher elevations. Be particularly cautious around corniced ridges, cross-loaded features, and convex rollovers.
Continue to assess for wind slabs in exposed, alpine terrain features.

A group of skiers remote-triggered a size 2 avalanche on a wind-loaded convex roll in the Wheaton area on Sunday. Check out the associated MIN here.
If you go into the backcountry, please submit your observations to the Mountain Information Network.
A widespread surface crust likely exists up to roughly 1500 m.
At higher elevations recent snow has been redistributed by winds from various directions. Deeper deposits of wind slabs can be found in exposed terrain.
In some areas, a weak layer of facets or surface hoar may persist, down approximately 50 to 80 cm from the surface.
