Middle Lys Valley

Field observations and stability tests have shown a favourable avalanche situation.

Field observations and stability tests have shown a favourable avalanche situation.

Where night cloudy cover will be most persistent: The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. Until the temperature falls small and, in isolated cases, medium-sized moist and wet avalanches are possible. Backcountry tourers or freeriders can release avalanches in some places, with a large load in most cases. They are rather small. Such avalanche prone locations are to be found on extremely steep southeast, south and southwest facing slopes. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls. In steep terrain there is a danger of falling on the hard snow surface. Gradual decrease in danger as the temperature drops.

Thursday: In the afternoon on extremely steep south facing slopes individual mostly small avalanches were released. As a consequence of highly fluctuating temperatures a crust formed on the surface during the last few days, in particular on sunny slopes below approximately 2800 m. In some localities a partly overcast night: The surface of the snowpack is hardly frozen at all. This applies already during the night. In shady places that are protected from the wind intermediate and high altitudes: Towards its surface, the snowpack is dry and has a loosely bonded surface. Snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying. In the south-east of the region, watch out for the numerous rocks hidden by the little recent snow. Towards its base, the snowpack consists of faceted crystals. This applies in particular on steep east, north and northwest facing slopes,.

The avalanche danger will persist.
