The avalanche danger is 4- strong from the Valgrisenche to the Gran S. Bernardo, 3-considerable in Valsavarenche, Rhêmes, Valpelline passing from Valtournenche to Ayas and Gressoney and 2-moderate elsewhere.
Critical areas are difficult to detect due to the bad weather and snowfall in progress.
The avalanche problems are "wind drifted snow" and "new snow".
We have different situations depending on the areas with an increase in the degree of danger from east to west due to the new snow accompanied by strong wind from the western sides.
- Several small avalanches from very steep slopes and rocky bars;
- Medium-sized slab avalanches from leeward slopes. Locally, according to the morphology of the slopes, in the W sector, some of them will reach the valley floor in the habitual canals making a long way;
- Under the limit of the forest, the new snow settles on a damp snowy mantle, also in the cold slopes the internal structure of the snowpack is unfavorable - slab avalanches are likely to affect much of the thickness of the snowpack from the steep slopes.
- new and recent accumulations, bigger and thicker in the N-NO of the Region, close to ridges and hills, near slope changes and in the basins above 2200 m. A hiker / skier can trigger of fairly compact and thick slabs, especially on the steep north, east and south slopes.
- weak persistent layers thick layers of cohesion-free crystals inside the snowpack. They are mainly located on the coldest slopes in the shade, in the altitude that starts from 1800 m up to 2600 m at the most. Rest the risk of a skier to solicit these weak layers and trigger slabs, even at a distance.
