On Friday conditions will be mostly sunny in the mountains. There will be moderate and locally strong southwesterly winds in the west and foehn winds in the valleys of the north. On Saturday it will be mostly sunny at first, then clouds will gather from the west. There will be light winds.
The avalanche danger will decrease, but only slowly in Valais, Grisons and the south due to the weak structure of the snowpack.

As the day progressed, it became partly sunny from the west. In the south, it was very cloudy and it snowed, especially during the night. The snowfall level was mostly between 1200 and 1500 m.
From Tuesday morning to Wednesday morning, the following amounts fell above approximately 2000 m:
At midday at 2000 m, around 0 \u00b0C
It will be very cloudy in the south and a little snow will fall above 1600 m overnight to Thursday. It will be sunny in all other regions.
Up to 5 centimetres in the south
At midday at 2000 m, between +3 \u00b0C in the north and -1 \u00b0C in the south
In westernmost and northern Lower Valais, there is somewhat more snow at high altitudes than is usual at this time of year. Elsewhere, the snow depths are below average and in the south they are well below average. On south-facing slopes and generally below 2400 m, the snowpack is mostly wet or crusted.
On the Main Alpine Ridge and to the south of it, the fresh snow and wind slabs of the past two days are lying on a thin but heavily faceted old snowpack at high altitudes.
North of the Main Alpine Ridge, there was little transportable snow, meaning that despite strong southerly winds, only small wind slabs were created in some localities. Primarily on northern and eastern slopes above approximately 2400 m, the old snowpack contains some pronounced weak layers, particularly in the inneralpine regions of Valais and throughout Grisons, but hardly any avalanches have been reported for days.
