Particularly in the Valais south of the Rhone, in Grisons south of the Anterior Rhine and in the Gotthard region, the uppermost layers of the snowpack are marked by a weak layer over widespread areas. In this layer, isolated avalanches have been triggered by persons on west-facing, north-facing and east-facing slopes during the last few days. Avalanches fractured down to more deeply embedded, even to ground-level layers of the old snowpack in isolated cases, in places where the snow was shallow more than anywhere else.
Also in the remaining regions of Switzerland, this weak layer on shady slopes is evident in some places. Avalanche triggerings in this layer have been reported only in isolated cases. During nights of clear skies, the snowpack surface can freeze down to intermediate altitudes. As a result of the daytime warming and solar radiation, the danger of wet-snow and gliding avalanches increases on sun-drenched slopes during the course of the day.

Nighttime skies were clear. During the daytime it was quite sunny in spite of high-altitude cloudbanks. During the afternoon convective cloud build-up was evident in the western regions.

-

At midday at 2000 m, +1 °C in the northern regions and +3 °C in the southern regions.

During the nocturnal hours winds were intermittently blowing at moderate strength from northerly directions; during the daytime, predominantly light winds from the west prevailed.

Nighttime skies will be predominantly clear. During the morning hours it will be quite sunny to start with, subsequently cloud cover will move in from the west and the south. However, it is expected to remain dry.

-

At midday at 2000 m, between +3 °C in the northern regions and +1 °C in the southern regions.

During the night, predominantly light southwesterly winds are anticipated, intensifying during the course of the day, then blowing at moderate to strong velocity in the afternoon in the western regions, in the foehn-exposed regions and in general in the high alpine regions.
