Middle Lys Valley

The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m.

The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m.

The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack in particular on very steep shady slopes. At high altitude the avalanche prone locations are more prevalent. Single winter sport participants can release avalanches in some places. In some places the avalanches can be triggered in the faceted old snow, in particular on very steep slopes. Several mostly small snow slides and avalanches are possible as a consequence of the new snow.

5 to 15 cm of snow has fallen since Saturday above approximately 2000 m. Wednesday: 5 to 10 cm of snow, but less in some localities, will fall from the afternoon above approximately 1400 m. The weather conditions gave rise to gradual moistening of the snowpack in some cases especially at low and intermediate altitudes. Large-grained weak layers exist in the old snowpack on shady slopes. The new snow of the last few days is lying on surface hoar in some places. In all altitude zones a little snow is lying on south facing slopes. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.

In some localities up to 10 cm of snow will fall on Thursday. The fresh snow and the mostly small wind slabs must be evaluated with care and prudence.
