Maira and Grana Valleys

New snow and wind slabs in the afternoon. The prevalence of the avalanche prone locations will increase.

New snow and wind slabs in the afternoon. The prevalence of the avalanche prone locations will increase.

Midday and afternoon: Snowfall above approximately 1000 m. The mostly small wind slabs can be released in particular on very steep shady slopes at intermediate and high altitudes, in particular in gullies and bowls, and behind abrupt changes in the terrain. Additionally in very isolated cases avalanches can be released in the old snowpack and reach medium size. Sunny slopes: The surface of the snowpack will freeze to form a strong crust and will hardly soften at all. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. Watch out for the numerous rocks hidden by the recent snow.

Some snow will fall from midday over a wide area. The snowpack is faceted and its surface consists of loosely bonded snow lying on a crust. This applies especially on shady slopes. Large-grained weak layers exist in the snowpack on shady slopes. In particular steep sunny slopes: The surface of the snowpack has frozen to form a strong crust and will hardly soften at all.

Gradual increase in avalanche danger as a consequence of new snow and wind.
