On Wednesday morning, the perturbation from north passed through our Region has generally brought a few cm of snow above 1500 m, the only significant peaks were in the areas of La Thuile, Val Veny and Gran San Bernardo, where in the zones strictly bordering with France and Switzerland 20-30 cm of new snow were recorded above 2500 m, but in a very localized and irregular pattern. The weak snowfall was accompanied by strong northern winds.
Surface wind or melt and freeze crusts or, rarely, facets on the colder slopes and in sheltered plateau.
In the older part of the snowpack, where present, the weak layers are made by facets. It is unlikely to break them because they are often buried deep inside the snowpack and in any case the overlying crusts are very hard and thick. Locally the wind erosion may have brought facets closer to the surface.
Snow is absent in the bottomávalley and poor in the middle mountain.
Good snowcover above 2200-2400 m, but the snowpack has been heavily worked by the wind, with eroded areas where they are most exposed to the wind.
Natural avalanches in the last 24 hours
In theánorth-western border area of the region, one smallánatural slab have been reported on very steep slopes, above 3000 m at the southern aspects.
Skiing conditions: bad to good, frequently variable in few meters.
It is possible to wear the skis above 1800-2300 m, better to choose skitours with roads that lead at higher altitude.
Above 2000-2400 m, where it has snowed on Wednesday, we ski on dry and cold powder snow, or on very hardáwind crusts, while at lower altitudes there are refrozen crusts, hard and irregular.
There are many sastrugi, mainly at high altitude.
Useful crampons or rampant for the hardest areas.
