Snowpack

There are weak layers in the snowpack, especially near the surface. Some of these are still prone to triggering above approximately 2400 m. There are hardly any weak layers in the lower part of the snowpack that are prone to triggering. With new fallen snow and wind, fresh wind slabs will form on Thursday as the day progresses.

To date, gliding avalanches have mainly occurred on east-, south- and west-facing slopes below around 2600 m and, less frequently, on north-facing slopes below around 2200 m. Although gliding avalanche activity has decreased somewhat, such avalanches could still be released at any time of day or night and may be large in regions with a lot of snow.

Weather forecast until Thursday, 01.02.2024

Wednesday night into Thursday will be mostly clear. In the early morning, cloud will move in rapidly from the north, and precipitation will set in in the late morning. The snowfall level will be at 1400 m. It will be partly clear in Valais and mostly sunny in the south.

• eastern Bernese Alps, central and eastern parts of the northern flank of the Alps: 10 to 15 cm;
• Prättigau, Silvretta, Samnaun: 5 to 10 cm;
• elsewhere: a few centimetres in the north, dry in the south.

On both days, there will be some moderate westerly winds in the north and moderate to strong northerly winds in the high Alpine regions and in the south.
