It will be very cloudy and precipitation will fall during the night. The snowfall level will rise from 1500 m to 2300 m. In the north and Valais, 20 to 40 cm of snow will fall at high altitudes, and up to 50 cm will fall from the Bernese Oberland to central Switzerland. Less snow will fall in Grisons and it will remain dry in the far south. There will be a westerly wind, which will be strong in the north but moderate elsewhere. On Monday, it will be sunny and mild and the wind will ease.
On Sunday, the danger of dry avalanches will increase at high altitudes. Below approximately 2300 m, the danger of wet and gliding avalanches will increase with the rain. In the west and north, danger level 3 (considerable) will be reached in many places over the course of Sunday. On Monday, the avalanche danger will decrease below approximately 2300 m, but will not change significantly at higher altitudes.

There will be a westerly wind that will be:
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. In the west, these are heavily overlaid and therefore only triggered occasionally. In the other regions, they are closer to the surface. However, the overlying layers have since undergone a structural transformation and have become softer. For this reason, only isolated fractures have been reported here as well.
In many places, there is some loose fresh snow lying on the surface from the last 3 days and some surface hoar (hoar frost). These will be transported on Saturday during the course of the day.
