Snowpack
On north-facing slopes, the surface of the snowpack is often faceted and loose. The moderate to strong foehn wind in the north will transport this loose snow. Rather small, hard, but easily triggered snowdrift accumulations are developing. Otherwise, avalanches may still be triggered in places in the west and north in older, near-surface layers of the snowpack.
In southern Valais, Grisons and Ticino, there are weak layers in the lower part of the snowpack. In these regions, avalanches may be triggered in places in the fresh and somewhat older drifted snow, and in some cases may also sweep away deeper layers of the snowpack. Isolated avalanches may also be triggered directly in deep layers, especially in the Engadine and south of there.
Gliding avalanches, some large, are still possible.

Outlook
During the night to Sunday, a little snow will fall in the far west above 1700 m. On Sunday it will remain mostly cloudy on the northern flank of the Alps with some final precipitation. It will be quite sunny in the afternoon in Valais, Ticino and Grisons. There will be light winds. On Monday it will be mostly cloudy with bright spells mainly in the south and east. There will be a light to moderate southwesterly wind. The zero-degree level will be around 2000 m.
The risk of dry avalanches will decrease. Occasional gliding avalanches are still possible.
