Moderate avalanche danger will be encountered over a wide area

Snowpack
The snowpack structure on the northern flank of the Alps is favourable over widespread areas. Only in isolated cases can avalanches be triggered in a weak layer above or beneath the rain crust which formed at the end of December. On the other hand, from the central Valais over the northern Ticino as far as Grisons weak layers are evident more deeply embedded inside the snowpack. Nevertheless, no further avalanches have triggered from these layers for more than a week.
As a result of solar radiation and daytime warming cycles, gliding avalanches and loose-snow avalanches are possible on the northern flank of the Alps on very steep south-facing slopes more than anywhere else.

Outlook through Sunday, 16.01.2022
Following nights of clear skies it will be sunny in the mountains during the daytime. Particularly on Saturday it will be quite mild once again.
The danger of dry-snow avalanches will continue to decrease incrementally. As a result of the mild temperatures and solar radiation, wet-snow and gliding avalanches are possible on very steep sun-exposed slopes.
