Weak layers in persistent weak layers are prone to triggering!
The avalanche risk is considerable above around 1800 metres and low below. The situation is precarious for winter sports. Medium-sized slab avalanches can easily be triggered by individuals in some places, especially from west to north to east, but also in a few places in the southern sector. Remote triggering is also possible in isolated cases. If wind slabs are disturbed near the surface, there is a high likelihood of avalanches breaking through to deeper layers. The old snowpack is poorly built up across the board: Avalanche prone locations are barely recognisable and require a defensive route choice. In particular, be careful near transitions from a little to a lot of snow and in the entrance areas to steep gullies. On sunny slopes, small loose snow slides can spontaneously detach from very steep slopes during the daytime changes.
Snowpack
A bound snow slab of former new or drift snow overlays soft layers (e.g. surface hoar, faceted crystals) or older, hard wind slabs. The snow surface is at least moistened up to around 1500 metres, even higher on sunny slopes. The snow surface can cool down overnight and is crusted can form and hardness in the morning. In general, areas with little snow alternate with considerable snowdrift accumulations. Breaks usually occur between the fresh and slightly older layers of drift snow or near the crust that forms the transition to the completely angular old snowpack. Under this crust, the old snowpack consists of deep rime and angular forms, which are interspersed with other crusts in areas with more snow. Snow from early winter can sometimes be found on the ground in the form of a hardness melt-freeze crust.

Weak layers in persistent weak layer can still be disturbed
The avalanche risk is moderate above around 1800 metres and low below that. Medium-sized slab avalanches can still be triggered by individuals in some places, especially from west to north to east, but also in a few places in the southern sector. Slabs near the surface can tear through the persistent weak layer. Avalanche prone locations are hardly recognisable and require a defensive route choice. Take particular care near transitions from a little to a lot of snow and in the blown-in entrance areas to steep gullies. On sunny slopes, small loose snow slides can spontaneously break loose from very steep slopes during the daytime changes.

Danger level
Low avalanche danger and little snow
The avalanche risk is low, there is little snow. Isolated avalanche prone locations are still conceivable on steep, shady slopes leading to wind slab-filled gullies in the summit areas. In general, the risk of injury from stones and the risk of falling on hard or icy surfaces outweighs the risk of burial.
Snowpack
The snowpack is at least superficially moistened up to around 1500 metres, on sunny slopes even up to the summit areas. The cloudy night prevents the snowpack from stabilising and crusting can form again on the surface. As a result, it is usually sticky and heavy again in the morning hours. Only on shady slopes can the snow surface still be partly soft and dry or wind-treated. Here, edged persistent weak layers - if present - weaken the thin snow base, fundament.
Tendency
No significant change in avalanche danger.

Weak layers in persistent weak layer can still be disturbed
The avalanche risk is low. Above around 2200 metres, small slab avalanches can still be triggered in a few places in the west to north to east sector. Danger areas are located at the transition from little to more snow and generally next to blown-off areas as well as in the entrance areas to gullies and bowls filled with wind slab. Some of the avalanche prone locations are difficult to recognise. The risk of falling and injury generally outweighs the risk of burial, be careful in the area of terrain traps.

The snowpack is at least superficially moistened up to around 1500 metres, on sunny slopes even up to the summit areas. The snow surface can cool down overnight and is crusted can form and hardness in the morning. Only on shady slopes can the snow surface still be partly dry and soft or wind-treated. Here, older snowdrift accumulations overlay a weak old snowpack, which now consists mainly of faceted crystals or deep rime. Weak layers prone to triggering are mainly found in the weak old snow foundation, but occasionally weak layers of surface hoar are also prone to triggering at the transition from older wind slab to old snow.
