In the old snowpack there are always weak layers (facets and striated crystals, deep and surface hoar) interspersed with old melt-and-freeze and wind crusts: they are a latent instability between 2000 and 2800 m, at all the aspects.
However the rise in temperatures in progress, accompanied by a good night temperature refreezing, leads to a gradual improvement in the snowpack stability, going to slowly deactivate the persistent weak layers, at least at the southern aspects.
The surface humidification at the moment concerns the sunniest aspects and partially those in the shady locations at lower altitudes.
Avalanche activity last 48 hours
On Friday two triggering medium sized slabs (40 cm thick) has been surveyed at 2100-2200 m, NE aspect, close to slope/ridge changes.
Small avalanches of loose wet snow from the sunny steep slopes, in correspondence of rock bands below 2800 m. Some glide-snow avalanches from the steep grassy slopes.
Discrete amounts of snow in the west and north of the region, even if well below the average for the season; elsewhere the snowcover is enough only above 2200 m.
In general, ridges, passes and several bumps are eroded to the ground or to the old hard snow.
In the west and north of the Region skiing conditions still discrete to good, especially in the areas more sheltered and shady: still powder snow or lightly hardened by the wind.
On the steep sunny slopes we have almost spring conditions, with superficial wet snow and melt-and-freeze crusts already up to 2600-2800 m, sometimes already unbreakable.
Towards the south-east of the Region the snow is strongly compacted by the wind and it is possible to touch stones, on the bumps and below 1900-2300 m.
Generally in correspondence of ridges
and passes, hard snow, old or very compacted by the wind: necessary the rampant.
