Persistent weak layers
- Above 2,000 m
Weak old snowpack with little snow.
Weak old snowpack with little snow.
The avalanche risk is moderate in the northern sector above 2000 metres and low below that. In skiable terrain next to blown-off areas, small to medium slab avalanches can be triggered in some places by low additional loads. In the higher elevations, wind slabs are prone to triggering and avalanches triggered on the surface can tear through the persistent weak layer. Whumpfing collapsing sounds when stepping on the snowpack can indicate danger.
From midday, 5 cm to 10 cm of snow will fall on a locally very variable snow surface. Areas with little snow are located next to snowdrift accumulations. In places, these have been transformed and are soft and in places hard as a board. Where there is an old snowpack, there are faceted crystals on and under the crust at the transition to it, which can serve as a weak layer. Fractures in the persistent weak layer usually occur here. Deeper in the old snowpack there is a sequence of faceted crystals, crusts and a lot of deep rime. The total snow depth is well below average.
Cloudy weather will set in on Sunday and visibility may be limited at times, especially at higher altitudes. Brief clearing will remain the exception. In the afternoon it will snow about 5 cm in showers, 10 cm in the Kitzbühel Alps and on the Hochkönig. The wind will remain mostly weak and shift from southeast to northwest during the day. It will cool down during the day. At 2000 m -2 to -6 degrees.
No significant change in avalanche danger.
