Savognin

The fresh snow and wind slabs from the past two days are lying on soft layers, especially on slopes that are protected from the wind, and in some places surface hoar has also been covered by snow. With the mild temperatures, the wind slabs are settling and stabilising rapidly. However, it is still possible for avalanches to be triggered at the transition to the old snowpack.

Up to 2400 m, the snowpack has been soaked by the rain down to around 2100 m. The snowpack will stabilise somewhat during the mostly clear night into Tuesday.

On shady slopes above approximately 2400 m and in the high Alpine regions in general, there are faceted weak layers deep in the old snowpack. With the new and drifted snow of the past two days, fractures are again possible in isolated cases. Avalanches may then become large.

There was still widespread precipitation in the north overnight to Monday. The snowfall level rose to around 2300 m. It was mostly sunny during the day.

Fresh snow

From Saturday night to Monday morning, the following amounts fell above around 2400 m:

• Northern flank of the Alps, northern Valais, northern Prättigau: 20 to 30 cm, locally up to 40 cm
• Rest of Valais, rest of Gotthard region, rest of northern Grisons: 10 to 20 cm
• Elsewhere less than 10 cm across a wide area, dry in the very south

Temperature

At midday at 2000 m, around +4 °C

Wind

From the west:

• Strong during the night in the north and generally at high altitudes, storm force at times
• Light to moderate during the day.

After a mostly clear night, it will be sunny and very mild.

Temperature

At midday at 2000 m, between +8 °C in the north and +4 °C in the south

Wind

Light to moderate southwesterly

After mostly clear nights, Wednesday and Thursday will be mostly sunny and mild. The zero-degree level will be around 3100 m on Wednesday and 2700 m on Thursday. There will be a light to moderate southwesterly wind.

The risk of dry avalanches will continue to decrease. The danger of wet avalanches will change over the course of the day and will increase a little during the day. Gliding avalanches are still possible on steep grassy slopes.
