| New snow and weather|
During the weekend, above 2000 m 15-25 cm of new snow, higher amounts (30-40 cm) in the Lys valley and close to Piedmont and generally at higher elevations (>3000 m). The new snow is moistening during the hottest hours of the day below 2300-2700 m depending on the areas and aspects. But the sharp drop in temperature forecast in the next day will dry again the snow
The winds still in action have poorly moved the snowpack, eroding a few inches of snow. From Monday evening the northern winds will act more on the great amount of loose snow, especially along the border reliefs with Switzerland, where the winds will have greater intensity.
Surveyed avalanche activity in the last 48 h
Several natural release avalanches of loose dry snow on the shady slopes between 2200 and 2800 m and small and medium-sized slabs mainly at sunny aspects have been reported. A medium-sized full-depth avalanche from a very steep grassy slope occurred below 2500 m.
Triggered releases: a remote distance triggered avalanche, of medium size, northern aspect, at 2900 m. Still some whooms reported.
The new snow of the weekend has a good bond with the old snowpack which, although still presenting some critical issues (overlapping slabs), is slowly consolidating according to the weight of the new snow and the gradual humidification, especially where ventilation is scarce.
Below 2200 m, the basal layers of the snowpack, close to the ground, are often damp/wet (typically spring crystals).
- from absent to discrete up to 1500 m;
- excellent from 1900 m to 2800 m;
- good above 2800 m, but less homogeneous, with partly eroded ridges, north walls exposed to ice and bumps and filled gullies.
In the lateral valleys you can put on your skis right from the bottom of the valley.
Generally powdery snow, nice to ski above 2100-2300 m mostly on the northern slopes, in humidification below 2300-2500 m depending on the areas. In high mountains, different areas with snow drifted by the wind. The recent snow on the south slopes lays on a melt and freeze crust up to 2500 m.
