Snowpack

Thursday's and Friday’s fresh snowfall and wind have resulted in snowdrift accumulations, especially in the high Alpine regions. These are deepest on the northern Alpine ridge and in Grisons. Below 3000 m, the last few days' fresh snow is lying on water-saturated old snowpack. On north-facing slopes above around 3000 m and on other aspects above around 3500 m, the new fallen snow of the last few days is lying on a still mostly dry snowpack. Some of the fresh and drifted snow is still prone to triggering, especially in these altitude zones. In the north, there will be some light snowfall above approximately 2400 m on Sunday and small snowdrift accumulations will develop with westerly winds.

Moist loose snow avalanches are possible in regions with fresh snow where conditions are sunny.

OutlookMonday and Tuesday

The nights to Monday and Tuesday will be partly clear in the south, but elsewhere mostly cloudy. On Monday, 10 to 30 cm of snow will fall above 2400 m on the central and eastern parts of the northern flank of the Alps and in northern Grisons, less elsewhere. In the south, conditions will be sunny with cumulus clouds and showers in the afternoon. The zero-degree level will be between around 2600 m in the north and 3000 m in the south. On Tuesday, it will be cloudy in the north with some light snowfall above 2200 m. There will be sunny spells in Valais and the south. On both days, winds will be light and occasionally moderate from westerly directions at high altitudes.

The risk of dry avalanches in the high Alpine regions may increase slightly in the north with the fresh snow, but will decrease in the south. Moist loose snow avalanches from the fresh snow will be possible where conditions are sunny.
