The snow drift accumulations formed at the weekend by the strong northerly wind remain prone to triggering on shady slopes in particular.
In particular in Valais and Grisons, avalanches can be released on north and east facing slopes, and in some case on west facing slopes as well, in a weak layer near the surface of the snowpack. In these weak layers, several avalanches, in some cases dangerously large ones, have been triggered by people in recent days. In particular in places with shallow snow cover, individual avalanches have penetrated near-ground layers of old snow in their track.
As the effects of warming and solar radiation increase, the danger of wet snow and gliding avalanches will escalate as the day progresses.

On Monday night the skies were clear over a wide area. During the day the weather was sunny.
