Middle Lys Valley

Fresh wind slabs represent the main danger. The wind slabs are barely recognisable because of the poor visibility.

Fresh wind slabs represent the main danger. The wind slabs are barely recognisable because of the poor visibility.

The strong wind will transport the new snow significantly. The wind slabs will be deposited on soft layers at intermediate and high altitudes. As a consequence of new snow and a sometimes strong wind from southerly directions, further wind slabs will form in the course of the day adjacent to ridgelines and in pass areas as well as above the tree line. Fresh and somewhat older wind slabs can be released easily, even by a single winter sport participant, in all aspects. In particular at high altitudes and in high Alpine regions these avalanche prone locations are more widespread and the danger is slightly greater. During the day: More dry and moist avalanches are possible, even medium-sized ones, in particular on very steep sunny slopes, and on wind-loaded slopes.

25 to 40 cm of snow, and up to 60 cm in some localities, has fallen since Tuesday above approximately 2000 m. This applies in particular along the border with Switzerland. On Thursday the wind was moderate to strong. Friday: Little snow will fall until the evening. In some places new snow and wind slabs are lying on soft layers. A lot of snow is lying at intermediate and high altitudes, in particular along the border with Switzerland. The old snowpack is favourably layered.

The avalanche danger will increase during the day. Dry and moist avalanches are to be expected as the precipitation becomes more intense.
