New snow requires caution. Wind slabs are to be avoided.
As a consequence of new snow and a moderate to strong wind, easily released wind slabs will form in all aspects. The avalanche prone locations are to be found in particular in steep terrain above the tree line and in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are medium-sized. In very isolated cases dry avalanches can also be triggered in the old snowpack, especially on very steep shady slopes at transitions from a shallow to a deep snowpack, this applies in particular in case of a large load.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 20 to 40 cm of snow will fall. The fresh wind slabs are bonding poorly with the old snowpack in particular on shady slopes. The new snow and wind slabs are lying on the quite favourable surface of an old snowpack on sunny slopes at intermediate altitudes. In its middle, the snowpack is faceted and weak, especially on shady slopes. Only a small amount of snow is lying for the time of year. Fresh wind slabs are to be evaluated with care and prudence.

Distinct weak layers in the old snowpack are treacherous. Fresh wind slabs are to be evaluated with care and prudence.
Distinct weak layers in the old snowpack can still be released by individual winter sport participants in particular on west, north and east facing slopes. This applies in particular between approximately 1600 and 2500 m, in isolated cases also on steep sunny slopes at elevated altitudes. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can reach large size. Remotely triggered avalanches are possible. Over a wide area easily released wind slabs will form. The avalanche prone locations are to be found in particular on steep shady slopes above the tree line and adjacent to ridgelines and in gullies and bowls in all aspects. Avalanches can penetrate deep layers and reach large size. In addition a latent danger of gliding avalanches exists.
Snowpack
dp.7: snow-poor zones in snow-rich surrounding dp.6: cold, loose snow and wind
Faceted weak layers exist in the centre of the snowpack, especially on west, north and east facing slopes between approximately 1600 and 2500 m, in isolated cases also on sunny slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall. As a consequence of new snow and a moderate wind from northwesterly directions, wind slabs will form in the course of the day. The fresh wind slabs are bonding poorly with the old snowpack in particular on shady slopes and generally at elevated altitudes. The new snow and wind slabs are lying on the quite favourable surface of an old snowpack on sunny slopes at low and intermediate altitudes.
Tendency
A sometimes treacherous avalanche situation will persist. Distinct weak layers in the old snowpack necessitate defensive route selection. As a consequence of rising temperatures, rain up to approximately 2000 m and the strong northwesterly wind, the snowpack can not consolidate.

New snow
Treeline
The new snow represents the main danger.
Over a wide area up to 30 cm of snow, and up to 40 cm in some localities, will fall until the early morning above approximately 800 m. This snow must be evaluated with care and prudence in particular on steep shady slopes above the tree line. In particular in the regions exposed to heavier precipitation individual small and medium-sized slab avalanches are to be expected as the snowfall becomes more intense. The new snow can be released by a single winter sport participant especially on shady slopes at high altitude. As a consequence of new snow and wind, wind slabs will form during the night in particular adjacent to ridgelines.

Avalanches can in very isolated cases penetrate deep layers and reach large size in isolated cases. Avalanches can be released in the weakly bonded old snow, even by small loads in isolated cases. The avalanche prone locations are to be found in particular on steep shady slopes above the tree line. They are rather rare but are difficult to recognise. Caution is to be exercised at transitions from a shallow to a deep snowpack.
