During a night of clear skies a crust capable of bearing loads forms over widespread areas on sunny slopes. As a consequence of daytime warming and solar radiation this crust then thaws and the snowpack subsequently forfeits its stability. Wet-snow and gliding avalanches are possible. In the last few days only very few wet-snow avalanches have been recorded in spite of the mild temperatures and sunny skies.
In the inneralpine and the southern regions of Grisons, as well as in the southern Valais, deeply embedded inside the snowpack there are pronounced weak layers evident. These layers can react with unusual sensitivity to moistening. Moist and wet-snow avalanches can, in those places, sweep away these deep layers inside the snowpack or fracture directly in those layers. They can, in some places, be triggered by persons.
The snowpack on south-facing slopes below approximately 3000 m, on east-facing and west-facing slopes below approximately 2500 m, and on north-facing slopes below approximately 1600 m, is thoroughly wet.

Following a night of clear skies it was sunny during the daytime hours.

At midday at 2000 m, between +5 °C in the western and the southern regions and +2 °C in the eastern regions.

Winds on the northern Alpine Ridge were blowing at moderate strength, in the other regions of Switzerland at light strength, from southeasterly directions.

Following a night of clear skies it will be sunny.
