Avalanche Activity

Wind slab on weak persistent layer

The avalanche risk is moderate above around 1800 metres. Pillows of wind drifted snow can be triggered in a few places, especially in steep terrain exposed to the east. In the northern and eastern exposures, there is also still a persistent weak layer problem at altitudes above the tree line. If the old snowpack is torn through, the avalanches can sometimes reach medium size. Caution in the area of terrain traps. Sunny slopes can release wet slides from very steep slopes.

Snowpack Structure

A layer of snow of varying thickness (largest in the Totes Gebirge) or thin pillows of wind drifted snow cover a partly very variable and mostly hard old snowpack. There is significantly more snow in shady gullies and bowls than on sunny slopes, some of which are partly bare up to 2000 metres. In the northern and eastern exposures, the snowpack continues to be weakened by layers with faceted crystals and floating snow, and the persistent weak layer problem remains.

Weather Forecast

In the night to Monday, high fog will establish itself again, reaching up to 2000 metres. During the day, it will be slightly foehn and often sunny with moderate to strong south-easterly winds. Temperatures at 2000 metres will be between -4 and -1 degrees, at 1500 metres around -1 degree.

Tendency

No significant change in avalanche danger.
