Middle Lys Valley

Gradual increase in danger of dry and moist avalanches.

Gradual increase in danger of dry and moist avalanches.

As a consequence of new snow and wind the prevalence and size of the avalanche prone locations will increase as the day progresses. In some cases the various wind slabs have bonded poorly. Several medium-sized and, in isolated cases, large snow slides and avalanches are possible in all aspects. Mostly the avalanches are shallow but can be released even by a single winter sport participant, especially on steep slopes. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack in particular on very steep shady slopes above approximately 2500 m. In some places the avalanches can be triggered in the faceted old snow.

10 to 15 cm of snow, and even more in some localities, fell on Sunday above approximately 1800 m. 10 to 20 cm of snow will fall on Monday above approximately 1500 m. Moderate southeasterly wind. Large-grained weak layers exist in the old snowpack on shady slopes. 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.

Wind and new snow: 10 to 20 cm of snow will fall on Tuesday above approximately 1200 m.
