Avalanche prone locations in wind slab, in the higher altitudes also in persistent weak layers

Avalanche prone locations in wind slab, in the higher altitudes also in persistent weak layers

The avalanche risk is moderate from the sparse high forest upwards. The last wind slab can be triggered in some places with little additional load, slab avalanches can reach medium size. All aspects and both adjacent to ridgelines and steep terrain far from ridgelines are affected. At higher elevations (especially on western, northern and eastern slopes), avalanches can also break through into the persistent weak layer and occasionally become large if the additional load is high. The drift snow areas are not recognisable everywhere. Small gliding avalanches are occasionally possible on very steep sunny slopes.

The abundant new fallen snow that fell under stormy conditions from the west to north in the middle of the week has settled significantly and is already slightly moistened and crusted on sunny slopes up to over 2000 metres. In exposed areas, the snowpack is marked by the storm, with 5 to 10 centimetres of new fallen snow covering the wind tracks. Fractures are possible, especially in the last wind slab, but also partly in the old snowpack, in which faceted crystals (partly on crusts) and deep rime weaken the structure both near the surface and deeper inside. This mainly affects high altitudes on shady slopes (W-N-E) and high alpine locations.

The last snow showers will subside during the night, but it will remain cloudy. On Monday, the light will be diffuse due to clouds above summit level, but visibility will initially be sufficient. From midday, higher altitudes will be covered in fog as the north-westerly wind picks up and snow showers will pass through. In exposed areas, the wind will reach speeds of around 60 km/h. Temperatures at 2000 m -9 to -6 degrees, at 3000 m -14 to -10 degrees.

Between 10 and 30 cm of new fallen snow by Tuesday. The risk of slipping snow increases.
