Weakly bonded old snow represents the main danger.
Weak layers in the old snowpack can be released in some places by individual winter sport participants. The avalanche prone locations are to be found on very steep west, north and east facing slopes above approximately 2200 m. 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 serve as an alarm indicating the danger. Avalanches can reach medium size. In very isolated cases avalanches can also penetrate deep layers. Such avalanche prone locations are to be found on very steep north facing slopes above approximately 2800 m. Avalanches can in isolated cases reach large size. Meticulous route selection is recommended.
In addition individual mostly small gliding avalanches are possible. This applies on steep grassy slopes below approximately 2400 m.
Snowpack
dp.1: deep persistent weak layer
Over a wide area 20 to 40 cm of snow, and even more in some localities, has fallen since Monday. The wind was light to moderate. New snow is lying on a weakly bonded old snowpack. This applies on west, north and east facing slopes above approximately 2200 m. Released avalanches and reports filed by observers confirm the existence of a weak snowack especially at elevated altitudes.
Tendency
Weak layers in the old snowpack necessitate caution.

Weakly bonded old snow requires caution.
Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants. The avalanche prone locations are to be found on steep west, north and east facing slopes above approximately 2200 m. These places are barely recognisable, even to the trained eye. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Avalanches can reach medium size. Meticulous route selection is recommended.
In addition individual mostly small gliding avalanches are possible. This applies on steep grassy slopes below approximately 2400 m.

Over a wide area 20 to 40 cm of snow, and even more in some localities, has fallen since Monday. The wind was light to moderate. In some places new snow is lying on a weakly bonded old snowpack. This applies on west, north and east facing slopes above approximately 2200 m.

Wind slab

Persistent weak layer
2200m
Fresh wind slabs require caution. Weakly bonded old snow at elevated altitudes.
The wind slabs of the last few days can be released by a single winter sport participant. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in west to north to southeast facing aspects above approximately 2200 m. The wind slabs are clearly recognisable to the trained eye. Avalanches can reach medium size. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach quite a large size, in particular on steep shady slopes above approximately 2200 m, as well as in gullies and bowls. Steep, glaciated terrain must also be critically assessed.
Only isolated gliding avalanches are possible.
The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
A little snow is lying. The snowpack will be subject to considerable local variations. In the last few days the wind was moderate to strong. The fresh wind slabs are lying on soft layers especially on steep shady slopes. Faceted weak layers exist in the bottom section of the old snowpack. Isolated whumpfing sounds and snow profiles show the unfavourable bonding of the snowpack.
Tendency
Wind slabs must be evaluated with care and prudence in particular on steep shady slopes at elevated altitudes. Weakly bonded old snow requires caution.

Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
From a snow sport perspective, in most cases insufficient snow is lying. The snowpack will be subject to considerable local variations. In the last few days the wind was moderate to strong. The fresh wind slabs are lying on top of a weakly bonded old snowpack especially on steep shady slopes.
Tendency
Wind slabs must be evaluated with care and prudence in particular on steep shady slopes at elevated altitudes.

Gliding snow
2400m
Gliding avalanches and moist snow slides are possible. Weakly bonded old snow requires caution.
On steep grassy slopes individual gliding avalanches are possible, especially on sunny slopes below approximately 2400 m. In addition below approximately 1800 m, small wet loose snow slides are to be expected.
Weak layers in the lower part of the snowpack can be released in very isolated cases in particular on very steep shady slopes. Such avalanche prone locations are to be found on shady slopes above approximately 2200 m. Such avalanche prone locations are very rare but are difficult to recognise.
Snowpack
dp.2: gliding snow dp.1: deep persistent weak layer
Over a wide area 20 to 40 cm of snow, and even more in some localities, has fallen since Monday. The wind was light to moderate. The snowpack will be in most cases well bonded. Isolated avalanche prone weak layers exist in the old snowpack on steep shady slopes. This applies in particular in places that are protected from the wind at elevated altitudes.
