Middle Lys Valley

In particular in regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more widespread and the danger is level 3 (considerable).

As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs will form in the course of the day. In the afternoon the natural avalanche activity will gradually increase. These can in particular be released in near-surface layers. Places where weaknesses exist in the old snowpack are especially unfavourable. In particular here the avalanches can be triggered in deep layers of the snowpack and reach medium size in isolated cases. Backcountry touring and other off-piste activities call for meticulous route selection. In steep terrain there is a danger of falling on the hard snow surface.

Thursday: 10 to 30 cm of snow, but less in some localities, will fall from midday above approximately 2000 m. The strong wind will transport the new snow significantly. The fresh snow and the mostly small wind slabs will become increasingly prone to triggering. They will be deposited on a weakly bonded old snowpack especially on very steep shady slopes.
