Maira and Grana Valleys

Intensive snowfall. Sharp increase in avalanche danger.

Intensive snowfall. Sharp increase in avalanche danger.

Up to 30 cm of snow, and even more in some localities, has fallen thus far above approximately 2300 m. 60 to 100 cm of snow, and even more in some localities, will fall until the evening above approximately 2300 m. The sleet will give rise to thorough wetting of the snowpack over a wide area below approximately 2300 m. On steep slopes more frequent medium-sized and, in isolated cases, large moist and wet avalanches are possible as a consequence of the precipitation. Individual weak layers exist in the old snowpack in particular at high altitudes and in high Alpine regions. Avalanches can in isolated cases be triggered in the old snowpack and reach quite a large size. The avalanches can reach the bare valleys in particular from very steep starting zones.

Over a wide area new snow is lying on a moist old snowpack. The sleet will give rise to increasing moistening of the snowpack in particular at intermediate and high altitudes. Isolated avalanche prone weak layers exist in the snowpack at high altitudes and in high Alpine regions. Below approximately 2000 m a little snow is lying.
