Weather Forecast
Monday: clear conditions in the morning with light snowfall developing by mid-day and intensifying slightly overnight / moderate southwest winds / freezing level at 1900m Tuesday: broken cloud / light to moderate westerly winds / freezing level at 1800m Wednesday: light snowfall / light southwest winds / freezing level at 1600m
Avalanche Summary
No new avalanches were reported form the region, but that may be attributed to the lack of observations. In a neighboring region glide crack releases to size 3 were observed at lower elevations while new storm slabs to size 1 were observed above 2000m.
Snowpack Summary
Last week, very warm temperatures affected all but the highest north facing slopes. Since Thursday morning, light to locally moderate amounts of new snow have formed soft slabs on the resulting crust at treeline and above while rain has continued to penetrate and weaken the snowpack at lower elevations. Up to 80cm below the surface, you'll find another crust that was reactive last week in the alpine and at treeline. The mid-February buried surface hoar layer is down about 140-220 cm, although avalanches releasing on this layer represent an extremely low probability-high consequence scenario. Cornices in the region are very large. With spring temperatures, these are more likely to become weak and fail. They could provide a large enough trigger to release deep layers on slopes below.
