The snow sport conditions outside marked and open pistes are critical.
In particular on west, north and east facing slopes more frequent medium-sized and, in isolated cases, large natural avalanches are possible during the first half of the night. In the regions exposed to heavier precipitation this applies especially. Avalanches can in many places be released in the old snowpack.
The danger exists in particular in alpine snow sports terrain. Natural avalanches and whumpfing sounds are a clear indication of a weakly bonded snowpack. Remotely triggered avalanches are probable. The avalanche prone locations are prevalent and are barely recognisable.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
10 to 25 cm of snow has fallen since Tuesday. 20 to 40 cm of snow, and even more in some localities, will fall. The new snow will be deposited on a weakly bonded old snowpack. Distinct weak layers exist in the old snowpack.
Tendency
The avalanche conditions remain precarious.

The conditions are precarious. The avalanche danger is within the upper range of danger level 3 (considerable).
In particular on west, north and east facing slopes more frequent natural avalanches are possible during the first half of the night. Avalanches can in many places be released in the old snowpack and reach medium size.
Natural avalanches and whumpfing sounds are a clear indication of a weakly bonded snowpack. Remotely triggered avalanches are possible. The avalanche prone locations are prevalent and are barely recognisable.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
In particular along the border with Slovenia and along the border with Italy in some localities up to 30 cm of snow has fallen since Tuesday above approximately 1200 m. 20 to 30 cm of snow, and even more in some localities, will fall. The new snow will be deposited on a weakly bonded old snowpack. Distinct weak layers exist in the old snowpack.
Tendency
The avalanche conditions remain unfavourable. The natural avalanche activity will decrease.

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 in particular on west, north and east facing slopes especially above approximately 1800 m. In many cases avalanches are medium-sized. Individual natural avalanches are not ruled out.
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. The avalanche prone locations are prevalent and are barely recognisable. Remotely triggered avalanches are possible.
Snowpack

In some localities up to 15 cm of snow has fallen since Tuesday. 15 to 30 cm of snow, and even more in some localities, will fall. The new snow will be deposited on a weakly bonded old snowpack. Distinct weak layers exist in the old snowpack.
Tendency
The avalanche conditions remain unfavourable.

A treacherous avalanche situation will prevail. Wind slabs and weakly bonded old snow require caution.
Distinct weak layers in the lower part of the snowpack can be released easily by individual winter sport participants. In addition the fresh wind slabs are very easily triggered. Avalanches can release the weakly bonded old snow as well and reach medium size. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line.
Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm indicating the danger. The avalanche prone locations are sometimes covered with new snow and are therefore difficult to recognise. Remotely triggered avalanches are possible. Caution and restraint are recommended.

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. 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.
