There are distinct weak layers in the middle and lower part of the snowpack, particularly on wind-protected shady slopes. These areas are particularly widespread south of a line from the Rhône to the Rhine and on the southern flank of the Alps. In these weak layers, medium-sized and sometimes even large avalanches can still be triggered by human activity. The snowpack on northern and eastern slopes in central Valais, as well as in northern Grisons, is particularly prone to triggering and remote triggering is also still possible in these areas in particular. On the northern flank of the Alps, isolated avalanches triggered in the old snowpack were last reported at the weekend.

Conditions were sunny in the mountains.

On Friday, it will be cloudy in the west and south with sunny intervals in the north-east. On Friday afternoon, precipitation will set in on the Main Alpine Ridge and to the south of it, which will continue until Saturday morning. The snowfall level will be at low altitude. There will be hardly any precipitation in other regions. On Saturday, it will be mostly cloudy on the southern flank of the Alps and in southern Grisons. Some precipitation may fall. Otherwise it will be dry with sunny intervals.

The avalanche danger will increase slightly with the fresh snow on the Main Alpine Ridge and south of it, but will hardly change elsewhere. Weak layers in the old snowpack will remain prone to triggering, especially in the inneralpine regions.
