The old snowpack contains various weak layers. In particular on wind-sheltered shady slopes, surface hoar is in some cases covered by snow. Deeper in the snowpack there are faceted layers, which in isolated cases are still prone to triggering, especially on seldom-used slopes with little snow cover. As daytime temperatures rise and the surface starts to moisten in some places, the likelihood of even dry avalanches being triggered is increasing during the course of each day.

In addition, wet snow avalanches are to be expected in all regions as the day progresses. Isolated wet slab avalanches may also be triggered by human activity. Especially north of a line from the Rhone to the Rhine, isolated gliding avalanches are still to be expected. These are also usually triggered during the course of the day.

After a clear night, it was sunny and very mild with a zero-degree level at 3500 m.

Temperature

At midday at 2000 m, around +10 °C

Overnight sometimes moderate from the north, light during the day

After a clear night, it will be sunny. With a zero-degree level at 3000 m, it will remain mild.

Fresh snow

Temperature

At midday at 2000 m, between +7 °C in the north and +9 °C in the south

Wind

Increasingly moderate from the northwest in the afternoon

Friday

During the night into Friday it will be partly cloudy in the south, while elsewhere it will be quite clear. During the day it will be quite sunny in the west and south, but no longer quite as warm as on the previous days. In the northeast it will be heavily overcast and a few snowflakes will fall above approximately 2000 m. The northwesterly wind will be strong in places at high altitude.

The danger of dry avalanches will continue to decrease. The danger of wet and gliding avalanches will increase in the west and in the south as the day progresses. In the northeast the danger will be mainly confined to lower-lying north-facing slopes, but will be present from the early morning onwards.

Saturday

After a partly clear night, it will be sunny and mild on Saturday. The zero-degree level will increase back up to 3000 m, and the wind will be light.

The danger of dry avalanches will continue to decrease. Due to the somewhat reduced nocturnal radiation, the danger of wet and gliding avalanches will increase rapidly as the day progresses.
