Avoid fresh wind slabs that are prone to triggering

Avoid fresh wind slabs that are prone to triggering

The avalanche risk is moderate. Above the tree line, the fresh wind slab can easily be triggered as a snow slab in some places even with little additional load. Avalanches can reach medium size. There are avalanche prone locations both adjacent to ridgelines and distant from ridgelines, as well as in steep gullies and in forest aisles. Drift snow areas are sometimes covered in snow and difficult to recognise.

In windless areas, there is 10 to 20 cm, in some places even 30 cm of new fallen snow from the last two days, while exposed places are heavily blown and snowdrift accumulations are correspondingly thick. Underneath is settled wind slab snow from the last week. At high elevations on shady slopes, there are still angular shapes and deep rime (also in combination with crusts) deeper in the old snowpack. Breaks are still possible here, especially with large additional loads, but are most likely to occur within the fresh drift snow packs.

During the night, a maximum of 10 cm of new fallen snow will fall in windy and cold weather on the northern slopes of the mountains. Tomorrow, Wednesday, visibility will often be limited by dense clouds and a few light snow showers will pass through during the day. The wind from the north will be weak to moderately strong. The temperature at 2000 metres will be between -9 and -6 degrees, at 3000 metres between -15 and -10 degrees.

Mixed weather with some snowfall and wind leads to a slow reduction in avalanche danger.
