In the north, it will be quite sunny on Saturday and partly sunny on Sunday. Over the second half of both days, cumulus clouds will form and isolated showers will be possible, although the amounts of precipitation will be small. The snowfall level will be around 1200 m. In the south, it will still be quite sunny on Saturday morning, and mostly overcast on Saturday afternoon and Sunday. Above 1000 to 1200 m, some snow will fall, especially during the night into Sunday and on Sunday morning. At present, around 10 to 15 cm of fresh snow is expected in the south, but the model forecasts are still very uncertain.
The danger of dry avalanches will generally continue to decrease. It may increase slightly, and temporarily, in the south on Sunday. Isolated wet snow slides and wet avalanches are still to be expected, especially from steep sunny slopes, but this activity will tend to be small and the avalanches will be mostly superficial.

Single winter sport participants can release avalanches. These can in some cases penetrate near-ground layers of the snowpack and reach large size. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.Near-surface layers on wind-protected shady slopes are lying on surface hoar in places. During the course of this week, snowdrift accumulations have formed in winds from varying directions, with Wednesday's strong winds being from the southeast. Some of the snowdrift accumulations are still prone to triggering.
In the inneralpine regions of Valais and Grisons, the layers of fresh and drifted snow are also lying on a weak old snowpack with pronounced near-ground weak layers. Avalanches can propagate into these deep weak layers in isolated cases or can be triggered directly in deep layers. In the other regions, there are still weak layers in the near-ground old snowpack in some places on shady slopes, but they are mostly so thickly covered that they are hardly prone to triggering.
