Over a wide area 15 to 30 cm of snow fell on Thursday. 15 to 30 cm of snow, and up to 40 cm in some localities, will fall until Friday. The fresh snow and in particular the wind slabs that are being formed by the sometimes strong northeasterly wind are prone to triggering. Avalanches can additionally be released in deeper layers on shady slopes, in particular above approximately 2400 m. Avalanches can reach large size in isolated cases. Backcountry touring calls for experience in the assessment of avalanche danger. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.

Snowpack & Weather

Snowpack

With new fallen snow and sometimes strong north to northeasterly winds, snowdrift accumulations are forming that are prone to triggering. In the north, where the most snow is falling, these are large. In the other regions, they are up to medium-sized. Deeper in the snowpack, there are faceted weak layers prone to triggering, especially on shady slopes above approximately 2400 m and generally in the high Alpine regions. Avalanches may also be triggered in these deeper layers at times, and isolated, naturally triggered avalanches are possible.

Outlook

A little snow will fall in the north during the night into Saturday. During the day, it will be partly cloudy in the north and east, and sunny in the west and in Ticino. There will be moderate northerly to northeasterly winds, strong in the west. It will be cold with around -10 °C at 2000 m. Clouds will gather rapidly in the west on Sunday, while it will remain sunny for longer in the east. The wind will shift to the west and will be strong in the north and west, moderate in the south.

The avalanche danger will decrease only slowly. Changing winds will create snowdrift accumulations that are prone to triggering. In addition, avalanches may be triggered in deeper layers of the snowpack, especially on north-facing slopes above 2400 m and in the high Alpine regions.
