Locally increased avalanche danger in the upper reaches of valleys bordering Piedmont.

Locally increased avalanche danger in the upper reaches of valleys bordering Piedmont.

At high altitude the avalanche prone locations are more prevalent. The avalanche danger will increase during the day. The new snow of the last few days is lying on the unfavourable surface of an old snowpack in particular on steep shady slopes. As a consequence of snowfall and the moderate wind, the snow drift accumulations will increase in size in the afternoon. Mostly the avalanches are shallow but can be released in some cases even by a single winter sport participant, especially on very steep slopes. Several small and medium-sized natural avalanches are possible as a consequence of new snow and strong wind.

20 to 30 cm of snow, and even more in some localities, has fallen since Saturday above approximately 2000 m. Wednesday: 10 to 15 cm of snow will fall in the afternoon above approximately 1400 m. 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.

In some localities up to 15 cm of snow will fall on Thursday. The fresh snow and the deep wind slabs can be released easily.
