Valgrisenche

New snow and wind slabs represent the main danger.

New snow and wind slabs represent the main danger.

As a consequence of new snow and a strong southeasterly wind, wind slabs formed in particular adjacent to ridgelines and in pass areas as well as above approximately 2200 m. Fresh wind slabs must be evaluated with care and prudence. In particular at intermediate and high altitudes the prevalence and size of the avalanche prone locations will increase. Even single skiers can release avalanches easily. The current avalanche situation calls for experience and restraint. Medium-sized and, in isolated cases, large natural avalanches are possible, also in all aspects on steep slopes.

20 to 30 cm of snow, and even more in some localities, has fallen above approximately 1500 m. The new snow is poorly bonded with the old snowpack. Caution is to be exercised on wind-protected shady slopes. Towards its surface, the snowpack is unfavourably layered and its surface consists of surface hoar,, also on steep sunny slopes. Towards its surface, the snowpack is unfavourably layered and its surface has a melt-freeze crust that is strong in many cases. A lot of snow is lying at intermediate and high altitudes.

The avalanche danger will persist. The northwesterly wind will transport the new snow.
