Avalanches can be released in the old snowpack. Mostly these are medium-sized and can be released even by a single winter sport participant. Caution is to be exercised in particular on west, north and east facing slopes above approximately 1800 m. Remotely triggered avalanches are possible.
The avalanche prone locations are and are barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack.
Mostly small loose snow avalanches are possible as a consequence of warming during the day and solar radiation.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
The new snow of the last few days is lying on top of a weakly bonded old snowpack in particular on west, north and east facing slopes above approximately 1800 m. Distinct weak layers exist in the old snowpack. Below approximately 1600 m: The snowpack is moist. Outgoing longwave radiation during the night will be good at times.
Tendency
Avalanches can as before be released, even by a single winter sport participant.

A treacherous avalanche situation will persist. The snowpack remains prone to triggering.
Avalanches can as before be released easily. Wind slabs and weakly bonded old snow require caution, especially on steep west, north and east facing slopes above the tree line as well as in areas close to the tree line. Avalanches can penetrate down to the ground and reach large size in isolated cases. The avalanche prone locations are difficult to recognise.
Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Remotely triggered avalanches are possible.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
The new snow and wind slabs of the last few days are lying on surface hoar in particular on wind-protected shady slopes. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above the tree line as well as in areas close to the tree line.
The snowpack will be moist at low altitude. On steep sunny slopes the snowpack will only just freeze.
Tendency
The avalanche conditions remain treacherous.

Weak layers in the old snowpack necessitate caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies on west, north and east facing slopes especially above approximately 1800 m. In many cases avalanches are medium-sized. Remotely triggered avalanches are possible.
The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger. Defensive route selection is important.
Mostly small loose snow avalanches are possible as a consequence of warming during the day and solar radiation.

Weakly bonded old snow represents the main danger.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. In some cases avalanches are medium-sized.
Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is higher.
Snowpack
dp.1: deep persistent weak layer
The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack on west to north to east facing aspects above approximately 1800 m. Distinct weak layers exist in the old snowpack. Outgoing longwave radiation during the night will be good at times.
Tendency
The weather conditions will facilitate a very slow stabilisation of the snowpack.
