Mostly favourable conditions despite reduced nocturnal outgoing radiation
Low avalanche danger in the morning. Danger zones for dry snow avalanches mostly in steep shady terrain, caution urged in transtions from shallow to deep snow, e.g. at entries into gullies and bowls. Due to higher temperatures and solar radiation, small-to-medium, in isolated cases also large-sized wet-snow and glide-snow avalanches are possible on very steep sunny slopes during the course of the day.
The snowpack is generally well consolidated and stable, despite reduced nocturnal outgoing radiation. On shady slopes there are weak layers in places. At high altitudes in exposed zones, fresh, small snowdrifts are apparent. Due to reduced nocturnal radiation and in zones where there is rain impact, the snowpack loses its firmness during the day.
Nocturnal hours: skies will be variably cloudy to heavily overcast, and mild. Sunday: clouds and fog with slight precipitation. Snowfall level will descend from 2000 m to 1500 m. In the afternoon, dry and clouds dispersing. At 2000 m: from +1 to -2 degrees. Strong W/NW winds.
On Monday, lots of sunshine, little cloud. Rising temperatures. The NW winds will slacken off. At high altitudes, fresh snowdrifts require caution. Danger of wet-snow avalanches will recede as temperatures drop.
