Persistent weak layers
- Above 2,000 m
Snowpack
There is appreciably less snow than usual at this time of year and snow conditions for ski touring are very poor, especially below 2000 m and generally in the east.
In all regions, the surface of the snowpack is faceted and loose on wind-protected shady slopes. Otherwise, the snowpack structure varies from region to region:

Fresh snow

Temperature
At midday at 2000 m, between -3 °C in the southwest and -9 °C in the northeast
Wind
Mostly moderate from northerly directions
OutlookFriday
In the north, it will be quite sunny in the morning, with clouds gathering during the course of the day. It will be sunny in the west and south. There will be a moderate to strong wind from the southwest. It will remain cold.
There will be hardly any change in avalanche danger. Despite sometimes strong southwesterly winds, snowdrift accumulations that are small but prone to triggering will form in some localities. South of a line from the Rhône to the Rhine, isolated avalanches may still be triggered in deeper layers of the snowpack.
Saturday
In the north, snow will fall at times during the night to Saturday and in the early morning. On the central and eastern parts of the northern flank of the Alps, 5 to 15 cm will fall down to low altitudes. It will be partly sunny in the afternoon. In the west and south, it is expected to remain dry and sunny during the day. There will be a moderate to strong wind from the southwest.
The avalanche danger will increase somewhat in the north. Fresh snowdrift accumulations will be deposited on a weak old snowpack and will be prone to triggering. Otherwise the avalanche danger will hardly change.
