Upper Susa and Chisone Valleys

Snowfall above approximately 1000 m. Gradual increase in avalanche danger as a consequence of new snow and wind.

Snowfall above approximately 1000 m. Gradual increase in avalanche danger as a consequence of new snow and wind.

Early morning: The more recent wind slabs can still be released in some cases in particular on very steep north, east and southeast facing slopes and generally at intermediate and high altitudes. In some cases the avalanches are medium-sized and can mostly be released by large loads. During the day: Gradual increase in avalanche danger as a consequence of new snow and wind. In the course of the day danger level 3 (considerable) will be reached at intermediate and high altitudes. In particular in the vicinity of peaks and in gullies and bowls small and medium-sized slab avalanches are possible as a consequence of the southeasterly wind. Additionally in some places avalanches can also be released in the old snowpack and reach quite a large size. Avalanches can be released, even by a single winter sport participant or triggered naturally. The avalanche prone locations are sometimes covered with new snow and are barely recognisable because of the poor visibility. Careful route selection and spacing between individuals are recommended.

Saturday: 15 to 30 cm of snow, and even more in some localities, will fall until the evening above approximately 1500 m. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. In particular in the vicinity of peaks hardly any snow is lying. Adjacent to ridgelines on north, northeast and east facing slopes hard wind slabs formed. The new snow will be deposited on a weakly bonded old snowpack in particular on shady slopes. The wind slabs of last week will be covered with new snow and therefore difficult to recognise. Stability tests have indicated that the stability of the snowpack varies greatly within a small area in particular on west to north to east facing slopes.

Sunday: Over a wide area snowfall above approximately 1000 m. As a consequence of the moderate to strong easterly wind, the snow drift accumulations will increase in size at the weekend. Further increase in avalanche danger in the course of the day.
