Middle Lys Valley

The fresh snow and in particular the wind slabs can be released easily.

The fresh snow and in particular the wind slabs can be released easily.

As a consequence of new snow and a strong wind from southeasterly directions, wind slabs will form in particular above approximately 2300 m. They can be released, even by a single winter sport participant and reach medium size. Especially in the areas bordering Piedmont most affected by the rainfall. In these regions the avalanche prone locations are more widespread. Here the avalanches can be released naturally. Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. This applies in particular on very steep northwest, north and northeast facing slopes above approximately 2500 m in places that are protected from the wind.

10 to 30 cm of snow, and up to 40 cm in some localities, will fall until the evening above approximately 2000 m. The fresh snow and very particularly the wind slabs are bonding poorly with the old snowpack. As a consequence of highly fluctuating temperatures a crust formed on the surface during the last few days, this also applies on shady slopes below approximately 2500 m. The spring-like weather conditions gave rise to increasing moistening of the snowpack on sunny slopes below approximately 2900 m, also on shady slopes below approximately 2400 m. As a consequence of falling temperatures a crust formed on the surface during the last five days. Towards its base, the snowpack is wet. This applies in all aspects below approximately 2400 m, and on sunny slopes below approximately 2900 m.

Significant increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
