Cold calm and clear is the trend till the end of the weekend. Expect lows dropping close to -30.

Snowpack Summary

Cold temps are beginning to facet the snowpack. Wide spread wind effect from last weekend is still visibly through the alpine. The Nov 8 crust is down 20-30 cm and present up to ~2400 m. The lower snowpack is a mix of weak facets & crusts. Snowpack depths at treeline vary from 60-90 cm with up to 140 cm in lee areas.

No new avalanches observed Thursday. Wind slabs have been the primary concern in the snowpack over the past week with several releases to size 1.5 triggered both with explosive and skier traffic.
