Prone to triggering and the persistent weak layer problem must be taken into account!
The avalanche risk is moderate above the tree line. In some areas, there are prone-to-triggering avalanches in the eastern sector and on the south side, which can be triggered as small to medium slab avalanches in filled-in steep slopes as well as in steep bowls and gullies with little additional load. As the wind shifts to the south, north-facing slopes are also blown in. Hardly recognisable individual avalanche prone locations due to the persistent weak layer problem are present in northern to eastern steep slopes. Here, snow slabs can also be triggered by individuals. This can occur both as drifting snow and in persistent weak layers.
Around 20 cm of new fallen snow may fall overnight. Strong winds from the northwest will form fresh, prone-to-triggering drifts that will bond poorly with the old snowpack. At higher elevations, the old snowpack remains largely unchanged with thin melt-freeze crusts and faceted crystals near the ground on the north and shady slopes, some of which are floating snow. The snowpack is still very unevenly distributed, even at higher altitudes there is only a little snow, often the new fallen snow falls on apery ground.
During the night, it will snow heavily in places. On Sunday, visibility will be limited by clouds and fog. It will snow lightly at times. Visibility will improve somewhat in the afternoon, but it will often only clear up towards the evening. Brisk north-westerly wind. Significantly colder with -8 degrees at 1500 m and -12 degrees at 2000 metres. On Monday, visibility will be repeatedly limited by clouds, fog and snowfall. In the morning the wind will still be blowing strongly from the south and will shift to the west during the day. At 1500 m around -2 degrees, at 2000 m around -5 degrees.
No significant change. Pay attention to wind slabs
