    Size
    1–1.5

    Previous strong winds from the SW have formed thin wind slabs in leeward and cross-loaded alpine features.

    The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Moderate
