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 2000 metres and low below. Above around 2000 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. Danger spots for this are located on very steep western, northern and eastern slopes, especially at the transitions 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 (crushed) harsch cover. On the sunny side only, the snow cover can soften somewhat during the day. Above around 2000 m, bound snow (due to rain or drift snow) lies on an old snow cover with soft layers of angular crystals, which are susceptible to disruption. These weak layers are found in particular on western, northern and eastern slopes. Below around 2000 metres, the remaining snow cover is often damp or wet right down to the ground.

Wednesday night will be partly foggy in the valleys, but only slightly cloudy above the fog cover. On the mountains, it will be very sunny and mild on Wednesday. The air will be extremely dry and visibility will be good. Temperature at 2000m: 4 to 8 degrees, at 3000m: around +1 degree. High winds: weak to moderate from the south-west.

Weak layers in old snow remain susceptible to disruption.
