New snow
- Above 1,800 m
Outlook
Conditions will be mostly sunny on Monday and Tuesday. Winds will be light to moderate from westerly directions. The zero-degree level will be around 2000 m.
Avalanche danger will decrease, but only slowly in southern Valais, Ticino and Grisons due to the weak snowpack structure. Occasional gliding avalanches are still possible.
Snowpack
The large volumes of fresh and drifted snow in the north are becoming increasingly stable. In southern Valais, Grisons and Ticino, some of Friday's snowdrift accumulations are still prone to triggering while some weak layers remain in the lower part of the snowpack. In these regions, avalanches may be triggered in drifted snow and sweep away deeper layers of the snowpack. Avalanches may occasionally also be triggered directly in deep snowpack layers.
Isolated gliding avalanches, sometimes large, are possible.
Weather forecast to Sunday
Apart from some high cloud, conditions will be quite sunny in the mountains. Especially on the northern flanks of the Alps and in northern Grisons, cloud cover will be somewhat thicker .
