||The avalanche danger is 3-considerable on most of the regional territory, 2-moderate from the Cogne Valley to the medium valleys of Lys and Ayas.|
Typical avalanche problem: wind-drifted snow.
For the morning of Monday, expected light snowfall with strong wind from NW (then from the afternoon from NE in decline), slightly more intense along the border reliefs with France and Switzerland. The new snow makes it difficult to identify pre-existing slabs and to form new ones, especially beyond the edge of the forest on the eastern and southern aspects.
In areas with danger level it is 3-considerable, above 2200 m, it is likely to cause the triggering of soft and hard slabs of considerable width and thickness already at the passage of a single skier, both on steep open slopes and inside the forest clearings, in particular at the eastern aspects,at the eastern and southern expositions (locally also the west) which are more heavily overloaded by the wind. On very steep/extreme slopes, in the gullies, and in slope changes, it is possible to release slabs, even at a distance with high overload, involving all the snowpack below down to the weak basal layer. The hard slabs are often well visible, spread over 2400-2600 m, where the snow distribution is even more irregular, while the soft ones are in an intermediate band between 2100 and 2600 m. These latter are difficult to detect and therefore can be very insidious. |
In the outdoor activities a good local evaluation of the avalanche danger is required and an accurate choice of the itinerary.
In areas with the danger level is 2-moderate the slabs are much less widespread and less thick and the triggering can occur with high overload, from very steep slopes above the tree line.
It 'expected a limited avalanche activity, especially along the border ridge with France and Switzerland, still windslabs and loose snow avalanches mainly of small size, in single cases also of large size with an important aerosol.
Avalanche danger trend: light decrease, Tuesday sunny with moderate / strong winds from NE, slabs in hardening.
