Upper Susa and Chisone Valleys

The snowfall will give rise to unfavourable bonding of the snowpack in particular at intermediate and high altitudes. The prevalence of avalanche prone locations and likelihood of triggering will increase from the early morning.

The snowfall will give rise to unfavourable bonding of the snowpack in particular at intermediate and high altitudes. The prevalence of avalanche prone locations and likelihood of triggering will increase from the early morning.

Above approximately 2000 m snow will fall on Sunday. Below approximately 2300 m medium-sized moist and wet avalanches are possible. Intermediate and high altitudes and: Avalanches can in isolated cases be triggered in the old snowpack and reach large size. The wind was moderate to strong adjacent to ridgelines over a wide area. During the course of the night wind slabs formed. This applies especially adjacent to ridgelines and in gullies and bowls at high altitudes and in high Alpine regions. The fresh snow as well as the wind slabs can be released by a single winter sport participant in isolated cases.

The surface of the snowpack will cool hardly at all during the overcast night. The snowfall will give rise in the late morning to unfavourable bonding of the snowpack in particular at intermediate and high altitudes. The sleet will give rise to increasing moistening of the snowpack in particular at low and intermediate altitudes. Isolated avalanche prone weak layers exist in the snowpack at high altitudes and in high Alpine regions.
