Valgrisenche

The fresh wind slabs represent the main danger.

The fresh wind slabs represent the main danger.

As a consequence of the occasionally moderate southwesterly wind, fresh snow drift accumulations will form on Tuesday. Especially in the border areas with France. The fresh wind slabs will be deposited on unfavourable layers in all aspects. These are mostly rather small but can in some cases be released easily, in particular adjacent to ridgelines and in gullies and bowls. This applies in particular on very steep slopes. In isolated cases avalanches can penetrate down to the ground. Natural dry avalanches are possible as the day progresses, but they will be mostly small.

Little snow fell on Saturday in some localities. Up to 15 cm of snow will fall above approximately 2000 m. On Tuesday the wind will be moderate at times in some localities. In some places wind slabs are lying on a weakly bonded old snowpack. Towards its surface, the snowpack is soft and has a loosely bonded surface. Steep sunny slopes: Underneath the fresh snow there is a more or less load-bearing refreezing crust. In all aspects snow depths vary greatly above approximately 2400 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying.

The weather report and anticipated change in the avalanche danger are uncertain. We recommend that you consult the most recent avalanche bulletin.
