Highlights

Conditions have improved but the nature of the snow pack still dictates concern for deeper slab releases. Best practice is to avoid rocky and thin snowpack areas in the alpine.

Avalanche problems

    Size

    Isolated wind-slabs exist in high alpine lee areas. Increased winds forecast for Friday may increase windslab development in the alpine.

    Several persistent weak facet layers exist in the mid-pack and at the bottom of the snowpack. Sporadic avalanche activity continues on these layers and the theme seems to be rocky, steep, thin snowpack areas in the alpine.
