    Wind slabs may be found at higher elevations, primarily in east facing terrain features (although wind direction has varied recently). New wind slabs may form through the day on Sunday, as snow is available for transport.

Expect early season conditions with a shallower than average snowpack, at treeline depths are between 40 and 60 cm. Below treeline snowpack depths taper off quickly.

Recent winds have varied in direction. these winds have scoured some terrain features in the alpine and formed small pockets of wind slab on exposed features.

A crust with facets below exists at or near the ground.
