Middle Lys Valley

New snow and wind slabs require caution. As a consequence of the ceasing of precipitation there will be a gradual decrease in the danger of moist and wet avalanches as the day progresses.

New snow and wind slabs require caution. As a consequence of the ceasing of precipitation there will be a gradual decrease in the danger of moist and wet avalanches as the day progresses.

As a consequence of new snow and a sometimes strong wind from southerly directions, sometimes large wind slabs formed in the last three days adjacent to ridgelines and in pass areas as well as above the tree line. As a consequence of wind from westerly directions, further wind slabs will form on Monday. Fresh and somewhat older wind slabs can be released easily or naturally in all aspects. During the day: Natural avalanches are further to be expected. The avalanches can be released in the new snow and wind slab layers and reach large size in some cases. As a consequence of falling temperatures, the natural activity of moist and wet avalanches will gradually decrease. Avalanches can reach valley bottoms and in some places endanger exposed transportation routes.

20 to 50 cm of snow, and even more in some localities, has fallen since Saturday above approximately 2000 m. Here rain fell up to 2000 m. The southerly wind has transported the new snow significantly. In some places new snow and wind slabs are lying on soft layers. The upper section of the snowpack is unfavourably layered. Sunday: Evening and night: Above approximately 2200 m 20 to 40 cm of snow will fall. The sleet will give rise to a loss of strength within the snowpack below approximately 2200 m.

Dry and moist avalanches are possible in some places.
