As a consequence of new snow and stormy weather a precarious avalanche situation will prevail.
Distinct weak layers in the old snowpack can be released easily by individual winter sport participants. Caution is to be exercised in particular on west, north and east facing slopes above approximately 2000 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Mostly avalanches are medium-sized.
As a consequence of new snow and a strong northwesterly wind, easily released wind slabs will form in particular above approximately 2000 m, in particular in gullies and bowls, and behind abrupt changes in the terrain. Individual natural avalanches are to be expected.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
Up to 15 cm of snow has fallen since Monday. The strong wind has transported the new snow. 10 cm of snow, and even more in some localities, will fall. As a consequence of a strong to storm force wind from northwesterly directions, further wind slabs will form in the course of the day. The various wind slabs are lying on surface hoar in some places.
Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above approximately 2000 m.

Distinct weak layers in the old snowpack can be released easily by individual winter sport participants especially in little used terrain. Remotely triggered avalanches are possible. Steep, little used shady slopes are to be avoided as far as possible. Mostly avalanches are medium-sized. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. The avalanche prone locations are difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger.
Fresh and somewhat older wind slabs are prone to triggering, in particular in gullies and bowls, and behind abrupt changes in the terrain above the tree line. They are clearly recognisable to the trained eye.
Restraint is advisable.

Distinct weak layers in the old snowpack can be released even by individual winter sport participants. Mostly avalanches are medium-sized. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 1800 m. The avalanche prone locations are difficult to recognise. Isolated whumpfing sounds can indicate the danger.
In addition the mostly small wind slabs in particular adjacent to ridgelines and in gullies and bowls are prone to triggering. This applies in particular above approximately 2000 m. They are clearly recognisable to the trained eye.

Distinct weak layers in the old snowpack can be released easily by individual winter sport participants especially in little used terrain. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. Individual avalanche prone locations are to be found also in areas close to the tree line. The avalanche prone locations are difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Mostly avalanches are medium-sized.
As a consequence of new snow and a strong northwesterly wind, easily released wind slabs will form in particular above the tree line, in particular in gullies and bowls, and behind abrupt changes in the terrain. Individual natural avalanches are to be expected.
In the regions neighbouring those that are subject to danger level 4 (high) the avalanche situation is more dangerous. Restraint is advisable.
Snowpack

5 to 15 cm of snow, and even more in some localities, has fallen since Sunday. 5 to 15 cm of snow, and even more in some localities, will fall until Wednesday. As a consequence of new snow and strong wind the wind slabs will increase in size additionally. Somewhat older wind slabs are lying on surface hoar in some places. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above the tree line.

Weak layers in the old snowpack necessitate caution. Fresh wind slabs require caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 2000 m. Mostly avalanches are medium-sized. Isolated whumpfing sounds can indicate the danger.
As a consequence of new snow and a moderate to strong wind, avalanche prone wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. This applies in particular above approximately 2200 m. The fresh wind slabs can be released by a single winter sport participant, but they will be small in most cases.
The number and size of avalanche prone locations will increase with altitude.
