Maira and Grana Valleys

The fresh snow and the wind slabs that are forming at intermediate and high altitudes represent the main danger.

The fresh snow and the wind slabs that are forming at intermediate and high altitudes represent the main danger.

As a consequence of snowfall above approximately 800 m and the occasionally strong easterly wind, fresh snow drift accumulations will form from the middle of the day, in particular in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of avalanche prone locations and likelihood of triggering will increase as the day progresses. The fresh snow and in particular the wind slabs that are forming in particular at intermediate and high altitudes can be released by a single winter sport participant in some cases. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.

The sometimes strong wind will transport the new snow. The fresh wind slabs are lying on soft layers in particular on shady slopes above approximately 2000 m. High altitudes and the high Alpine regions: Snow depths vary greatly, depending on the infuence of the wind. Towards its base, the snowpack is faceted and weak, in particular on steep east, north and northwest facing slopes,. The wind will transport the new snow.
