Monregalese Valleys

Down to low altitudes snow will fall on Saturday. Gradual increase in avalanche danger as a consequence of new snow and wind.

Down to low altitudes snow will fall on Saturday. Gradual increase in avalanche danger as a consequence of new snow and wind.

As a consequence of snowfall and the northeasterly wind, fresh snow drift accumulations will form during the next few days. These can be released by a single winter sport participant and reach medium size. This applies in particular on steep slopes at high altitudes and in high Alpine regions, as well as in gullies and bowls, and behind abrupt changes in the terrain. Dry loose snow avalanches and slab avalanches are possible from the afternoon. The fresh and somewhat older wind slabs will be covered with new snow and therefore difficult to recognise. Faceted weak layers exist in the old snowpack in particular on steep shady slopes. These can be released, mostly by large loads and reach large size in isolated cases.

40 to 80 cm of snow, and even more in some localities, has fallen since Friday above approximately 1800 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. In these regions the snowfall level rose to approximately 2000 m. The rain gave rise on Sunday to extreme moistening of the snowpack in particular at low altitude. High Alpine regions: Individual weak layers exist in the bottom section of the snowpack in particular on shady slopes. In the vicinity of peaks at high altitude a little snow is lying.

Saturday: Down to low altitudes snow will fall from the afternoon. The number and size of avalanche prone locations will increase in the afternoon.
