Maira and Grana Valleys

The wind slabs represent the main danger. In addition there is a danger of wet snow slides and avalanches.

The wind slabs represent the main danger. In addition there is a danger of wet snow slides and avalanches.

Weak layers in the old snowpack can be released in isolated cases even by individual winter sport participants in particular on very steep shady slopes. The avalanche prone locations for dry avalanches are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2500 m. More recent wind slabs are to be assessed with care and prudence. As a consequence of warming during the day individual small and, in isolated cases, medium-sized avalanches are possible below approximately 2500 m. This applies in particular in case of releases originating from very steep, sunny starting zones that have retained the snow thus far.

The strong wind has transported some snow. Weak layers exist in the centre of the snowpack on steep shady slopes. In some cases the wind slabs have bonded still only poorly with each other and the old snowpack. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on steep east, south and west facing slopes below approximately 2700 m.
