Avoid prone to triggering wind slabs

Avoid prone to triggering wind slabs

The avalanche risk is moderate. Above the tree line, the wind slab can be triggered as a snow slab in some places even with little additional load, below it is relatively well set. 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. Also be careful on and below cornices.

In wind-calmed higher elevations, there is 20 to 30 cm of new fallen snow from the last few days, depending on the area, in some places even over 40 cm, while exposed places are heavily blown and snowdrift accumulations are correspondingly thick. Underneath is settled wind slab snow from the last week. On shady slopes, there are 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.

On Thursday, mostly dense clouds will continue to prevail, with isolated periods of unproductive snowfall. The wind will be moderately strong. At 2000 metres, the temperature will be around -6 degrees.

Mixed weather leads to a slow reduction in avalanche danger.
