Highlights

Cooling trend leading into the weekend should tighten up a stressed, moist snowpack. Good riding quality and support at TL and Above but, improving at all elevations; quite good in the Alpine!

Weather Forecast

Wednesday: Cloudy with scattered flurries, High -2 C. Wind W: 15-35 km/h. FZL: 1900 m

Thursday: Cloudy with sunny periods and isolated flurries. Low -10 C, High -8 C. Wind west: 15-35 km/h.

Friday: Cloudy with sunny periods and isolated flurries. Low -9 C, High -6 C. Wind SW: 10-30 km/h. FZL: 1500 m

Snowpack Summary

Up to 25cm of new snow above 2000 m with minimal wind effect overlies sun crust at all elevations and a melt-freeze crust up to 2100m on all aspects. Snow pack below 1700m is mostly isothermal and unsupportive due to steady warm temperatures and rain.

Avalanche Summary

Natural slab/loose wet avalanche cycle occurring in the region, especially BTL. Control work producing predictable loose wet and loose slabs from low elevation targets. Few observations due to very poor visibility.

Confidence

Freezing levels are uncertain on Wednesday
