After softening of the often load-bearing melt-freeze crust, some large spontaneous wet snow avalanches are possible everywhere. Particularly at risk are steep areas in the extended northern sector between 2200 m and 2600 m, terrain that has not yet been discharged on high east, west and south-facing slopes, and generally those aspects where there is still a lot of snow. In wet snow, avalanches can tear through to the ground, run out untypically far and penetrate into the green. Triggering by winter sports and occasionally even remote triggering are possible.\n\nIn the morning, the avalanche risk is moderate above around 2400 metres in steep terrain from west to north to east. There are individual avalanche prone locations in the dry persistent weak layer, high alpine also in the southern sector. Take care in the transitions from little to lots of snow.",
