    Recent storm snow has started to settle into a slab which overlies a weak layer of facets and old surface hoar. Field teams were able to ski cut several small soft slabs to size 1 at treeline and below treeline elevations today.

    This weak layer exists below a strong mid-pack at treeline and sub-alpine elevations. Large loads such as a cornice collapse or surface slides could still possibly trigger this deep persistent weakness.

Weather Forecast

A return to colder conditions with a few snow flurries and light to moderate North Easterly winds in the alpine.

Snowpack Summary
