Please note: in the closed ski-resorts areas slopes are not managed and must therefore be considered as potentially avalanche terrain |
Recent snow The appreciable accumulations of recent snow of the past days are mostly found along the north-west border ridge, above 2400-2600 m, where locally 30-50 cm of fresh snow can be found. The night freezing and the diurnal increase in temperatures are favoring the progressive consolidation of recent snow (which in the hottest hours can be unstable however).
Snowcover The snow cover is uneven and lower than the average for the period. It is scarce in the mid-mountain and southern slopes, best in the north-west of the region. Bumps and ridges are often eroded, while channels and hollows have more snow.For ski touring in the south the snow is sufficiently continuous above 2200-2300 m, in the north above 1900-2100 m.
Snowpack stability The snowpack is isothermal and still has a superficial instability between the recent snow and the old one, moreover it is humidified in all its thickness below 2500-2700 m, even if it is slowly drying thanks to the thermal drop. There are unstable snow slabs at high altitudes, especially close to the ridges and in the canals.
Avalanches reported last 24h Numerous sluffs and small surface avalanches of wet and wet fresh snow have been reported at different aspects and altitudes. Some spontaneous slabs of medium size above 2800 m.
Conditions for skiing Dry loose snow only at high altitudes. Surface and central layers of the snowpack are wet up to 2500-2700 m. Conditions are not good for ski touring with very humid and breakable snow. |
