Monregalese Valleys

The snowpack will be unstable at high altitudes and in high Alpine regions. It is inadvisable to engage in backcountry touring in steep terrain.

The snowpack will be unstable at high altitudes and in high Alpine regions. It is inadvisable to engage in backcountry touring in steep terrain.

In the typical avalanche paths the avalanches can reach fairly large size. In particular in the vicinity of peaks and on steep slopes medium-sized and, in many cases, large slab avalanches are possible as a consequence of the northeasterly wind,, also in gullies and bowls, and behind abrupt changes in the terrain. Additionally avalanches can also be released in the old snowpack and reach large size. Whumpfing sounds and shooting cracks when stepping on the snowpack are a clear indication. Avalanches can be released, even by a single winter sport participant. Remotely triggered and natural avalanches are probable. The avalanche prone locations are prevalent and are barely recognisable because of the poor visibility. The conditions are unfavourable for backcountry touring outside marked and open pistes. The current avalanche situation calls for extensive experience in the assessment of avalanche danger and careful route selection.

40 to 60 cm of snow, and even more in some localities, has fallen since Friday above approximately 1600 m. As a consequence of new snow and a moderate to strong wind, sometimes large wind slabs formed since Friday in gullies and bowls and behind abrupt changes in the terrain as well as above the tree line. The new snow is lying on the unfavourable surface of an old snowpack in particular on shady slopes. Especially at high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind.

Tuesday: Some snow will fall in the late morning. Once the intense snowfall has ended, the avalanche activity will gradually decrease.
