Upper Susa and Chisone Valleys

Wind slabs and wet snow represent the main danger.

Wind slabs and wet snow represent the main danger.

The fresh snow of the last few days as well as the wind slabs represent the main danger. The avalanche danger should be investigated very thoroughly in the relevant locality. In the last few days sometimes easily released wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. The fresh wind slabs can be released, even by a single winter sport participant and reach medium size. Over a wide area a mostly overcast night: The surface of the snowpack will only just freeze. Below approximately 2400 m medium-sized and, in isolated cases, large moist and wet avalanches are possible. As the temperature drops there will be a gradual decrease in the danger of moist and wet avalanches as the day progresses.

In particular at higher altitudes snow depths vary greatly, depending on the infuence of the wind. The surface of the snowpack will only just freeze. In its middle, the snowpack is faceted, especially on steep shady slopes. On steep sunny slopes below approximately 2600 m only a little snow is lying.

Gradual decrease in avalanche danger as the temperature drops.
