Weak layers in the old snowpack can be released easily. This applies on steep slopes above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. In some cases the avalanches are large. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. <br/> <br/> In addition the fresh wind slabs at high altitudes and in high Alpine regions are easily triggered. Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. <br/> <br/> A considerable (level 3) danger of gliding avalanches exists. This applies on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided. <br/> <br/> Experience and restraint are required. Large quantities of fresh snow and the wind-drifted snow are lying on top of a weakly bonded old snowpack. This applies above approximately 2000 m. The large quantity of fresh snow and the wind slabs are lying on soft layers. <br/> Field observations confirm the existence of a weak snowack. The meteorological conditions will prevent a rapid change towards better conditions. 2023-12-03T16:00:00Z Avalanche.report 2023-12-03T23:00:00Z 2023-12-04T23:00:00Z Avalanche.report 3 DP2 DP6 gliding snow drifting snow decreasing 2023-12-04T23:00:00Z 2023-12-05T23:00:00Z Gliding avalanches and snow slides are the main danger. Fresh wind slabs are to be evaluated with care and prudence. On steep grassy slopes more medium-sized gliding avalanches are to be expected. Areas with glide cracks are to be avoided. <br/> <br/> As a consequence of a moderate to strong wind, avalanche prone wind slabs formed since Sunday. Avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. <br/> Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and a certain restraint. A lot of snow is lying for the time of year. <br/> <br/> The fresh wind slabs are lying on soft layers above the tree line. The old snowpack is largely stable. <br/> <br/> Low and intermediate altitudes: The old snowpack is wet. The avalanche danger will decrease gradually. 2023-12-03T16:00:00Z Avalanche.report 2023-12-03T23:00:00Z 2023-12-04T23:00:00Z Avalanche.report 3 2 DP4 DP2 old snow drifting snow gliding snow steady 2023-12-04T23:00:00Z 2023-12-05T23:00:00Z The snow sport conditions outside marked and open pistes are to some extent treacherous. Weak layers in the old snowpack can be released easily. This applies in particular on steep slopes above approximately 2200 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. In some cases the avalanches are large.

Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of the avalanche prone locations will increase with altitude. <br/> <br/> A latent danger of gliding avalanches exists. This applies on steep grassy slopes below approximately 2400 m, in the regions exposed to a lot of new snow in particular. Areas with glide cracks are to be avoided. <br/> <br/> Extensive experience in the assessment of avalanche danger and great restraint are required. Large quantities of fresh snow and the wind-drifted snow are lying on top of a weakly bonded old snowpack. This applies above approximately 2200 m. The new snow is lying on a crust below approximately 2600 m. The fresh wind slabs are lying on soft layers. <br/> Field observations confirm the existence of a weak snowack. <br/> <br/> Intermediate altitudes: The old snowpack is wet. The avalanche danger will persist. 2023-12-03T16:00:00Z Avalanche.report 2023-12-03T23:00:00Z 2023-12-04T23:00:00Z Avalanche.report 2 1 DP6 drifting snow steady 2023-12-04T23:00:00Z 2023-12-05T23:00:00Z Fresh wind slabs are to be evaluated with care and prudence.

Fresh wind slabs require caution.
