Weak layers in persistent weak layers are prone to triggering!
The avalanche risk is considerable above around 1800 metres and low below that. The situation remains precarious for winter sports. Medium-sized slab avalanches can easily be triggered by individuals in some places, especially from west to north to east. Remote triggering is still possible in isolated cases. If weak layers near the surface are disturbed, there is a high likelihood of avalanches breaking through to deeper layers. The old snowpack is poorly structured 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.
Snowpack
The snowpack is crusted can form and hard in the morning and softens a little on the sunny side during the daytime changes. Bonded snow overlays soft layers on the surface (e.g. surface hoar, faceted crystals) or older, hard packets of drifting snow. In general, areas with little snow alternate with considerable snowdrift accumulations. Breaks occur either in soft layers near the surface or around the crust that forms the transition to the completely angular old snowpack. Below this crust, the old snowpack consists of deep rime and angular forms, which are interspersed with other crusts in areas with more snow. The overall snow depth is well below average.
Tendency
The persistent weak layer problem remains.

Weak layers in persistent weak layers remain prone to triggering
The avalanche risk is moderate above around 2000 metres and low below that. Slab avalanches can still be triggered by individuals in some places, especially from west to north to east. Avalanches can tear through the persistent weak layer and become medium sized. Some avalanche prone locations are difficult to recognise and require a defensive choice of route. Take particular care near transitions from little to more snow and in the snow-covered entrance areas to steep gullies.

Weak layers in persistent weak layers can still be disturbed in a few places
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.
Snowpack
The snowpack is crusted can form and hard in the morning and softens again somewhat on the sunny slopes during the daytime changes. Only on shady slopes can the snow surface still be dry and soft or wind-treated in places. A thin, bound snow slab overlays a weak old snowpack, which now consists mainly of faceted crystals or deep rime. Prone to triggering weak layers are mainly found in the weak old snow foundation.
Tendency
No significant change in avalanche danger.
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 crusted can form and hard in the morning and softens a little on the sunny side during the daytime changes. Only on shady slopes can the snow surface still be partly dry and soft or wind-treated. Here, edged persistent weak layers - if present - weaken the thin snow base, fundament.
