Valgrisenche

Wind slabs above approximately 2400 m.

Wind slabs above approximately 2400 m.

The clearly visible wind slabs of the last two days can be released by a single winter sport participant in some cases in particular on north to east to southeast facing aspects above approximately 2400 m. In some places avalanches can also be released in near-ground layers. The moderate wind will transport the new snow. Above the tree line sometimes avalanche prone wind slabs will form. The prevalence of these avalanche prone locations will increase in the evening. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger.

5 to 25 cm of snow, and even more in some localities, will fall above approximately 2000 m. Individual weak layers exist in the snowpack at intermediate and high altitudes. Towards its surface, the snowpack is hard and its surface has a melt-freeze crust, especially below approximately 2300 m. Below approximately 2000 m only a little snow is lying.

10 to 20 cm of snow, and even more in some localities, will fall in all altitude zones. And in particular the wind slabs that are forming over a wide area represent the main danger. The danger will increase but remain within the current danger level.
