Wind slab
- Above 2,000 m
Snowpack
The large amounts of new snow in the south are stabilising. Large, naturally triggered avalanches are now unlikely. Newer wind slabs are prone to triggering in places, especially at high altitudes.
Isolated avalanche fractures in deeper layers of the snowpack have been observed in recent days in southern Valais, central Grisons and Engadine. On both the northern and the southern flanks of the Alps, there are hardly any weak layers deeper in the snowpack.
Below approximately 2200 m, the snowpack is wet due to the rain.
In the south, gliding avalanches are possible. These can become large and occasionally very large due to the high volumes of snow. Gliding avalanches are more rare in the north but they can also be large here in isolated cases.
Weather forecast until Wednesday, 03.04.2024
During Tuesday night into Wednesday, clouds will move in from the west and light precipitation will set in in the morning. During the day, it will be mostly cloudy with occasional precipitation. The snowfall level will increase a little during the day towards 1800 m in the north and 1500 m in the south.
New snow
The following amounts of fresh snow are expected above approximately 1800 m: widespread 5 to 10 cm, up to 15 cm in the extreme west of Lower Valais.
Temperature
At midday at 2000 m, between 0 °C in the north and -2 °C in the south.

Weather review for Tuesday, 02.04.2024
In the north, it was partly cloudy with snow showers in the morning and mostly sunny in the afternoon. The snowfall level was around 1200 m. It was mostly sunny in the south.
New snow
From Monday afternoon to Tuesday afternoon, the following amounts of fresh snow fell above approximately 1800 m:
Temperature
At midday at 2000 m, between -3 °C in the north and +1 °C in the south.
Wind
Trend until Friday, 05.04.2024
Thursday will be partly sunny in the north with some showers, especially in the second half of the day. The snowfall level will be around 2200 m and there will be little snow. It will be fairly sunny in the south. On Friday, it will be sunny and very mild in all regions.
The danger of dry avalanches will decrease. On Friday in particular, the danger of wet avalanches is expected to rise as the day progresses as a result of solar radiation and warmer daytime temperatures.
Gliding avalanches will also still be possible. These can become large, and occasionally very large in the south.
