Weekend characterized by strong wind and precipitations. The main snowfalls have been recorded in the northwest part of the region, the strong winds have definitively moved the snow.

New snow
The rain/snow limit has been at around 1100-1500 m.
The amount of fresh snow recorded is higher in the Northwest part of the region. Along the border with Switzerland and France (Valtournenche, Valpelline, Val Veny, La Thuile, Gran Paradiso valleys), at 2000 m asl, we have 15-20 cm. In the Gran San Bernardo and Val Ferret valleys peaks of 30 cm have been registered. In the central valley and in the eastern part of the region the amounts are lower, about 10 cm.

Wind and Temperatures
The wind has been the main actor of the weekend. In particular, since last night, strong winds from N have strongly wind-drifted the snow pack, with erosion even down to the ground. Temperatures dropped significantly with averaged values ​​at 8.00 am of -6C at 2000 m, -10C at 2500 m and -14C at 3000 m (-27C at Capanna Margherita, 4560 m).

Typical avalanche problems
The strong winds from N NW, especially at the end of the snowfall, have strongly wind-drifted the fresh snow, creating eroded areas down to the ground and accumulation zones. The avalanche problem, associated to the wind-drifted snow, with the possible release of hard slabs of fresh dry snow, is present particularly along the ridges at high altitude (> 3000 m). In general they can be more commonly found along the areas bordering with France and Switzerland and at the southern aspects.

The next report will be issued depending on the evolution of the snow and weather conditions.
