Highlights

Watch for wind slabs in exposed terrain on high alpine slopes, especially where they may overly facets. Two storms have formed most of the current snowpack, and it is a very supportive snowpack considering it is only November. Great ski conditions!

    Size
    1–3
    In thicker snowpack areas wind slabs have formed over previous storm snow and are less sensitive to triggering. In thinner snowpack areas these may be lying over weaker basal facets formed in late fall, and be more sensitive to skier triggering.

Weather Forecast

Sunday is expected to be moderately cool with a few flurries. 10 cm of snow and swirly winds are expected Monday night.

Snowpack Summary

80-100cm of supportive snow can be expected at treeline. Above treeline there is extensive wind slab development. The wind slabs  are a concern in thin snow pack areas or where underlain by weak facets. T
