Valgrisenche

The more recent wind slabs represent the main danger. They are to be evaluated with care and prudence in extremely steep terrain.

The more recent wind slabs represent the main danger. They are to be evaluated with care and prudence in extremely steep terrain.

Sunday: The wind was moderate to strong adjacent to ridgelines. Fresh wind slabs have formed especially adjacent to ridgelines and in gullies and bowls. The new snow and wind slabs can be released by a single winter sport participant. Caution is to be exercised at transitions from a shallow to a deep snowpack, in the regions exposed to a lot of new snow in particular on wind-protected slopes as well as. In particular along the border with France these avalanche prone locations are more prevalent and the danger is greater. Here the avalanches are medium-sized. Apart from the danger of being buried, restraint should be exercised in view of the danger of avalanches sweeping people along and giving rise to falls. The mostly small wind slabs are clearly recognisable to the trained eye.

The sometimes strong wind has transported the new snow significantly. 10 to 20 cm of snow fell on Saturday above approximately 1800 m, especially along the border with France. 5 to 15 cm of snow, and up to 20 cm in some localities, fell on Friday above approximately 2200 m. In all aspects snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. On steep sunny slopes below approximately 2500 m a little snow is lying. The snowpack is not distinctly layered. Shady slopes: The snowpack consists of faceted crystals and has faceted crystals on the surface.

The avalanche danger will decrease gradually.
