Middle Lys Valley

The wind slabs can still be released in some cases in particular on extremely steep shady slopes.

The wind slabs can still be released in some cases in particular on extremely steep shady slopes.

The new snow and wind slabs of last week are poorly bonded with the old snowpack in some places. The mostly shallow wind slabs can be released by a single winter sport participant in isolated cases above approximately 2200 m. Places where weaknesses exist in the old snowpack are especially unfavourable. These places are barely recognisable, even to the trained eye. Here the avalanches can be triggered in the weakly bonded old snow and reach medium size. Caution is to be exercised in particular on very steep northeast, north and northwest facing slopes at the base of rock walls and behind abrupt changes in the terrain.

Over a wide area 10 to 20 cm of snow has fallen since Thursday above approximately 1800 m. Several small and medium-sized avalanches were reported. The northwesterly wind has transported the new snow significantly. The fresh wind slabs are lying on top of a weakly bonded old snowpack especially on east to north to northwest facing aspects above approximately 2200 m. In particular at higher altitudes snow depths vary greatly, depending on the infuence of the wind. On the windward slopes, ridges, hills and crests are heavily eroded.
