In the west and south, it will be mostly sunny on both days. It will be partly cloudy along the Prealps and generally in the east. On Friday, light showers are possible in the east. In the mountains there will be a partly moderate northeasterly wind, with a moderate Bise wind in the Jura. The zero-degree level will rise to around 1600 m in the north and to 2200 m in the south.
The danger of dry avalanches will decrease. During the course of the day, moist loose snow avalanches from the loose snow and also gliding avalanches are to be expected.

With the sometimes strong Bise wind on Wednesday, some rather small but in some cases prone to triggering snowdrift accumulations will form, particularly along the Prealps and in the Jura. Otherwise, the large amounts of new snow and drifted snow in the north will slowly stabilise. In some places, however, the new snow of recent days is overlaid on faceted weak layers and in some cases also buried surface hoar, particularly on shady slopes. In these weak layers, avalanches can be triggered, including large ones.
In the inneralpine regions of Valais and especially Grisons, weak layers deeper in the snowpack are still prone to triggering in some places. Isolated avalanches may also be triggered in near-ground weak layers.
