Bulletin issued by few informations
Main avalanche problems: wind-drifted snow and new snow.
An intense disturbance is expected until Friday morning, especially in the western area of the Valley. The most consistent accumulations will occur above 2400-2500 m, altitude from where strong or very strong westerly winds can create many wind loads. A resumption of avalanche activity is expected due to wind and fresh snow, especially along the border ridge with France, where there will be more new snow.
Moving towards the SE, the quantities of new snow drop, as do the size and number of expected avalanches.
Mainly in the west: over 2500 m possible slabs, in some cases even very large and able to reach the valley floor along the usual gullies. Possible loose surface avalanches, especially of medium size, on very steep slopes and from rock bars at all aspects.
Especially in the western areas of the Valley and as the altitude rises, the slabs increase in size and diffusion. These are sensitive to the passage of the single skier already on steep slopes, close to ridges, hills or changes in slope above 2500 m. It is also possible to trigger avalanches of fresh wet snow, which can start from under the skis at lower altitudes.
