Monregalese Valleys

Down to low altitudes snow will fall. Further increase in avalanche danger in the regions exposed to heavier precipitation.

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 large size in isolated cases. This applies in particular on steep slopes also in areas close to the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain above the tree line. Dry loose snow avalanches and slab avalanches are possible already in the early morning. The fresh and somewhat older wind slabs will be covered with new snow and therefore difficult to recognise. Avalanche prone weak layers exist in the snowpack in particular on steep shady slopes. These can in some places be released by small loads and reach large size in isolated cases.

Stability tests and snow profiles show the unfavourable bonding of the snowpack on steep shady slopes. Precarious weak layers exist in the bottom section of the snowpack in particular on shady slopes. 30 to 40 cm of snow will fall until Sunday above approximately 1200 m. Over a wide area new snow is lying on surface hoar. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm indicating the danger.

The weather report and anticipated change in the avalanche danger are uncertain. The avalanche danger should be investigated very thoroughly in the relevant locality. Sunday: Down to low altitudes snow will fall until late morning. During the day: Moderate westerly wind. The number and size of avalanche prone locations will increase in the afternoon.
