Snowpack

The large volumes of fresh and drifted snow in the north are becoming increasingly stable. However, the bond to the old snowpack is still rather weak in places. In southern Valais, Grisons and Ticino, some of Friday's and Saturday's snowdrift accumulations are still prone to triggering, on the other hand some weak layers remain in the lower part of the snowpack. In these regions, avalanches can be triggered in drifted snow and fracture down to deep layers of the snowpack or occasionally be triggered directly in deep layers.

Isolated gliding avalanches, sometimes large, are possible.
