Outlook

In the north, it will be mostly sunny above approximately 2000 m on Tuesday and above approximately 1500 m on Wednesday, as well as in the inneralpine regions. Some snow may still fall in the Jura and the Prealps on Tuesday. The Bise wind will ease and and there will be light winds in the mountains.

In the south, it will be mostly sunny with light winds on both days.

Avalanche danger will decrease.

Snowpack

The most recent layers of new snow and snowdrift are still sometimes prone to triggering. On the Northern Alpine Ridge, in Valais, in the Gotthard region, in northern and central Grisons and in Engadine, the snow from December overlays weak layers, mostly in the area of melt-freeze crusts. This is most prevalent on north- and east-facing slopes, slightly less so on west- and south-facing slopes. Avalanches may be triggered in these weak layers.

In addition, above approximately 2800 m, where there was already a continuous old snowpack before the snowfall in the second half of November, there are some weak layers of faceted crystals on northern slopes. In these, avalanches may also be triggered in near-ground layers in isolated cases.
