The avalanche risk is moderate above 2000 metres and low below. Slab avalanches can be triggered in a few places by low additional loads and can reach medium size. Both fresh and older drift snowpacks as well as the weakly built-up old snowpack can be disturbed, fractures can tear through. Avalanche prone locations increase rapidly from the tree line upwards. They are concentrated from west to north to east, in some places in the southern sector in the high Alps, and generally next to blown-off areas. Drift snow areas should be avoided. Whumpfing collapsing sounds when stepping on the snowpack can indicate danger. The avalanche prone locations are difficult to recognise.
There is 5 to 10 cm of new/wind slab snow on a locally very varied snow surface. There are areas with little snow next to considerable snowdrift accumulations. In places, these have been transformed and are soft, in places hard as a board. The old snowpack consists of crusts with faceted crystals in between and deep rime. A break usually occurs around the uppermost crust. The total snow depth is well below average.
On Monday, visibility will be mostly good with variable cloud cover. The sun will shine at times. At 2000 metres around -6 degrees, at 3000 metres around -12 degrees. The wind will remain largely weak.
Slow decline in avalanche danger.
