Avalanche Activity

It is essential to pay attention to fresh loads prone to triggering and the persistent weak layer problem!

The avalanche risk is considerable in some areas above the tree line. In some areas in the eastern sector and on the south side, there are more extensive avalanches that can be triggered as medium slab avalanches in filled steep slopes and in steep bowls and gullies even with a small additional load. It is difficult to recognise individual avalanche prone locations due to the persistent weak layer problem in northern to eastern steep slopes. Here, snow slabs can also be triggered by individuals. This applies to both drift and persistent weak layers.

Snowpack Structure

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.

Weather Forecast

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.

Tendency

No significant change. Pay attention to wind slabs
