Fresh wind slab prone to triggering
The avalanche risk is moderate above the tree line and low below. In the north-west to north to south-east orientated steep terrain, small avalanches can be triggered by individuals in some places. Above 2000 m, small slab avalanches are also possible in a few places in persistent weak layers. Danger areas are located at the transition from little to more snow and generally next to blown-off areas as well as in the entrance areas to gullies and bowls filled with wind slab. Caution in the area of terrain traps.
During the night to Sunday, 10 to 15 cm of new fallen snow will fall on a small-scale surface. Fresh, prone to triggering snowdrift accumulations form, older snowdrift accumulations are covered with snow. On shady slopes protected from the wind above around 2000 metres, surface hoar has also been covered with snow in some cases. At high altitudes, especially in northern and eastern aspects, bonded snow overlays a weak old snowpack of faceted crystals and deep frost.
A cold front moves through during the night. It snows heavily in the first half of the night, but the snowfall decreases in the second half of the night. The amount of new snow is 10 to 15 cm. The north-westerly wind will pick up briskly. On Sunday, visibility will be limited by clouds and fog in the morning. It may also snow a little. Visibility will improve significantly from the south-west from midday and the afternoon will bring widespread good visibility and sunshine. Around -10 degrees at 2000 metres. A strong north-westerly wind will blow at high altitudes in the northern Alps, which will ease considerably towards the evening.
The wind picks up and fresh snowdrift accumulations continue to form. The persistent weak layer problem remains.
