Upper Susa and Chisone Valleys

Slab avalanches and moist loose snow avalanches are the main danger.

Slab avalanches and moist loose snow avalanches are the main danger.

The fresh snow and the wind slabs can be released easily, or, in isolated cases naturally and generally at intermediate and high altitudes. Mostly the avalanches are medium-sized and can be released even by a single winter sport participant. As a consequence of warming and solar radiation, the natural activity of moist and wet avalanches will gradually increase. This applies in particular on steep slopes especially at low and intermediate altitudes. Ski touring and other off-piste activities, including snowshoe hiking, call for experience in the assessment of avalanche danger and careful route selection.

Up to 60 cm of snow, and even more in some localities, has fallen since Saturday. Over a wide area new snow is lying on a hard crust. The new snow is bonding only slowly with the old snowpack in particular on shady slopes. The covering of new snow is soft and its surface has a crust that is not capable of bearing a load. The moderate wind has transported the new snow. Intermediate and high altitudes: Individual weak layers exist in the old snowpack especially on shady slopes.

The avalanche activity will gradually decrease.
