Critical and unusual avalanche situation because several negative conditions overlap:
- fresh snow: heavy snow fall on the border ridges; the fresh snow did not bond well with the old below;
- driftned snow: strong and very strong winds from the NW increase the loads and overload the slopes;
- persistent weak layers: present at the base of the snowpack. By overloading them, they collapse with bottom avalanches;
- wet snow: rain, even up to 1800 m, quickly destabilizes recent dry snow.

Natural avalanches:
many natural avalanches both with loose cohesion and slabs, both surface and ground. In the west and north of the region, particularly in the Mont Blanc area, they can be very thick and very large and can reach the valley floor, both with a dense component and with aerosols.
Probable small avalanches of wet snow from the slopes near the streets, that can invade the roadway.
In the south-east the danger is more limited due to the little snow present and therefore the avalanches will be smaller and less thick.

Avalanches triggered:
especially in the north-west, it is easy to cause the triggering of slabs already when a skier / hiker passes. The slabs can be both superficial and bottom. The danger is already present from 1700 m. Much experience is required in local hazard assessment and a prudent and defensive attitude is recommended.
Differences between the north-west and south-east of the region: in the south-east there is little fresh and recent snow and therefore it is easier to collapse the weak layers present in depth; in the north-west the main instability is superficial and linked to the loads of fresh and wind snow.

increasing degree of danger. The snowfalls continue, especially in the north-west, with very strong winds.
