In sintesi

Watch solar aspects in the afternoon. Solar triggered avalanches can be expected out of steep south facing terrain as the day warms up.

    Isolated windslabs exist at treeline and in alpine areas. It's hard to pin down exactly where these are, but several natural and skier triggered avalanches (up to size 1.5) have been reported in the past 48-hours.

Weather Forecast

A strong ridge of high pressure will dominate the region through the weekend bringing lots of sunshine and calm winds. Temperatures will start to warm on Thursday and by Friday freezing levels forecast to be around 1800 m.

Snowpack Summary

A well settled snowpack with few weaknesses exists throughout the region. Isolated wind slabs up to size 1.5 exist on leeward slopes at treeline and above from recent wind effect. Below 2000m, the Dec 3 layer of surface hoar remains visible and produces hard, planar test results in some areas but has not been reactive to skier traffic.

Avalanche Summary

Several natural and skier triggered wind slabs up to size 1.5 have been observed in the past 48 hours at and above treeline. Sluffs out of steep solar terrain were observed today with the warming temperatures.
