Weak old snow and sliding snow are the main dangers.

Weak old snow and sliding snow are the main dangers.

The avalanche danger is moderate above 2200 metres and low below. Above around 2200 m, slab avalanches can be triggered in places by individual winter sports enthusiasts. The avalanches usually remain small, but can occasionally become medium-sized if they break through into deeper layers. The danger spots for this are on very steep north and east-facing slopes, especially at the transition from little to much snow. Small, occasionally also medium-sized, spontaneous sliding snow avalanches are possible from very steep, still undischarged grass mat terrain.

The surface is dominated by (fractured) harsch cover. Above around 2200 m, bound snow (due to rainfall or drift snow) lies on an old snow cover with soft layers of angular crystals, which are susceptible to disruption. Below around 2000 m, the remaining snow cover is often moist or wet right down to the ground.

Thursday night will be partly foggy in the valleys, but only partly cloudy above the fog cover. Visibility will be good on Thursday. However, the sun will temporarily fade into the background. Extensive cloud fields as the foothills of a weak cold front move over the peaks. The summits themselves will remain clear. Temperature at 2000m: 0 to 3 degrees, at 3000m: around -3 degrees. High-altitude wind: mostly only weakly windy.

Weak layers in old snow remain susceptible to disruption.
