    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

Recent storm snow has started to settle into a slab which overlies a weak layer of facets and old surface hoar. Skiing was good today but field teams were very cautious around steep terrain where it was easy to ski cut several small soft slabs.

Avalanche Summary

Last nights warm conditions has turned the recent storm snow into a touchy slab. Field teams were able to trigger several small soft slabs to size 1. Two other small slides were reported off steep rocky terrain at lower elevations (BTL).
