With the mild weather, partly overcast nights and rain in places, moistening of the snowpack continued over the course of the last week. On south-facing slopes, the snowpack is water-saturated up to around 3000 m, and on east- and west-facing slopes up to 2500 to 2700 m, while on north-facing slopes it is water-saturated below 2000 m, with moistening progressing between 2000 and 2400 m.

In the south, fresh and drifted snow at high altitudes is in some places still prone to triggering, especially on shady slopes. Avalanches can also in some cases still be triggered by human activity in faceted weak layers in the old snowpack. Such danger zones are generally located at altitudes where the snowpack is becoming moist for the first time. In central Valais and in Grisons in particular, such avalanches can in some cases sweep away the entire snowpack, especially on slopes with light snow cover.

Overnight to Tuesday, skies were often cloudy with some widespread precipitation. In the north, the snowfall level fell from 1800 m down to 1500 m, while in the south it was around 2000 m. It was very sunny over the course of the day on the southern flank of the Alps and in high Alpine regions in the west, but often cloudy elsewhere.

Fresh snow

From Monday afternoon to Tuesday afternoon above approximately 2400 m:

• main Alpine ridge in Upper Valais, western Ticino: 10 to 20 cm
• elsewhere a widespread few centimetres

Temperature

At midday at 2000 m, around +4 °C in the west and south and 0 °C in the northeast

Wind

Light to moderate southerly during the night, backing northeasterly during the day

Overnight to Wednesday, there will be broken cloud in Grisons, with skies often clear elsewhere. It will be very sunny during the day. There is a possibility of isolated showers in the afternoon in the far south.

Temperature

At midday at 2000 m, around +5 °C

Wind

Light from variable directions

Skies will only occasionally be clear overnight to Thursday. During the day, it will be mostly sunny in Valais and in the south with sunny intervals elsewhere. After a mostly clear night, it will be very sunny during the day on Friday. The wind will be light from variable directions on both days. The zero-degree level will remain between 2600 m and 3000 m during the day.

The danger of dry avalanches will continue to decrease. The danger of wet avalanches will increase over the course of each day. Off-piste skiing and hut ascents should be completed in good time.
