Valgrisenche

Wind slabs and weakly bonded old snow represent the main danger.

70 cm of snow, and even more in some localities, has fallen since Sunday above approximately 2000 m. The large quantity of fresh snow as well as the wind slabs are bonding only slowly with the old snowpack in particular on shady slopes above approximately 2200 m. Weak layers exist in the snowpack in particular above the tree line. Over a wide area new snow is lying on a hard crust. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on very steep sunny slopes below approximately 2400 m.

Sunshine and high temperatures will give rise to increasing consolidation of the snowpack in particular on sunny slopes.

Wind slabs and weakly bonded old snow represent the main danger.

The Avalanche Warning Service currently has only a small amount of information about the snowpack. The wind slabs are to be found above approximately 2000 m. The new snow and wind slabs of last week are lying on the unfavourable surface of an old snowpack in all aspects above approximately 2200 m. Whumpfing sounds are a clear indication. Single winter sport participants can release avalanches in some places. In isolated cases these are large. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger. As a consequence of warming during the day and solar radiation dry and moist avalanches are possible as the day progresses, even medium-sized ones.
