Valgrisenche

Wind slabs represent the main danger, caution is to be exercised in particular along the border with France and along the border between Valais and Italy. In these regions the likelihood of avalanches being released is greater.

Wind slabs represent the main danger, caution is to be exercised in particular along the border with France and along the border between Valais and Italy. In these regions the likelihood of avalanches being released is greater.

As a consequence of a moderate to strong wind from northwesterly directions, sometimes deep wind slabs formed in the last few days at intermediate and high altitudes. The small quantity of fresh snow of Tuesday and very particularly the wind slabs to be found above all in gullies and bowls and behind abrupt changes in the terrain can be released by a single winter sport participant above approximately 2300 m. They are to be avoided in particular in very steep terrain, caution is to be exercised in particular above approximately 2600 m along the border with France and along the border between Valais and Italy. Here the avalanche prone locations are more prevalent and larger. On extreme slopes and at the base of rock walls mostly small dry snow slides are possible, in particular, along the border with France.

15 to 30 cm of snow, and even more in some localities, fell in the last few days above approximately 2000 m, especially along the border with France. The new snow is lying on a crust in particular on sunny slopes below approximately 2600 m. This snow is bonding only slowly with the old snowpack in particular on sunny slopes. In shady places that are protected from the wind: Towards its surface, the snowpack is dry and has a loosely bonded surface. Snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying.

The wind will be light. The weather conditions will facilitate a gradual strengthening of the snow drift accumulations.
