Avalanches can as before be released, even by a single winter sport participant. The snowpack remains prone to triggering.
Avalanches can as before be released easily. They can penetrate down to the ground and reach large size in isolated cases. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 1800 m as well as in areas close to the tree line. The avalanche prone locations are barely recognisable, even to the trained eye.
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 in isolated cases.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
Some snow will fall in some regions.
Above approximately 1800 m: The snowpack will be prone to triggering. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes.
Below approximately 1800 m as well as steep sunny slopes: The snowpack is fairly homogeneous and its surface has a crust that is barely capable of bearing a load.
Tendency
A treacherous avalanche situation will persist.

The conditions are precarious for backcountry touring and other off-piste activities.
Distinct weak layers in the old snowpack represent the main danger. The avalanche danger above the tree line is within the uppermost range of danger level 3 (considerable). In addition the wind slabs should be taken into account.
Weak layers in the old snowpack can be released even easily by individual winter sport participants. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. Avalanches can penetrate down to the ground and reach large size. 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 barely recognisable, even to the trained eye. Remotely triggered avalanches are possible. In addition the wind slabs in all aspects are prone to triggering in many locations.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Distinct weak layers exist in the old snowpack. This applies especially on west, north and east facing slopes. The snowpack remains generally prone to triggering. Outgoing longwave radiation during the night was reduced over a wide area. The snowpack will be moist at low and intermediate altitudes. Some snow will fall on Wednesday over a wide area.
Tendency
The avalanche danger will persist. Above the tree line a treacherous avalanche situation will be encountered over a wide area.

Avalanches can as before be released easily. Mostly they are medium-sized. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 2000 m. The avalanche prone locations are barely recognisable, even to the trained eye. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Remotely triggered avalanches are possible in isolated cases.
As a consequence of the occasionally strong wind, fresh snow drift accumulations will form on Wednesday. These are in some cases prone to triggering in particular on northwest to north to east facing aspects.

Wind slabs and weakly bonded old snow require caution.
Avalanches can be released by a single winter sport participant. This applies especially on steep shady slopes, as well as adjacent to ridgelines and in gullies and bowls above the tree line. As a consequence of the occasionally strong wind, fresh snow drift accumulations will form on Wednesday. These are in some cases prone to triggering. In some cases avalanches are medium-sized.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack

Some snow will fall over a wide area. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack at elevated altitudes. Faceted weak layers exist in the old snowpack.
Low and intermediate altitudes: The snowpack is moist and its surface has a melt-freeze crust that is barely capable of bearing a load.

The snowpack is unfavourably layered. In its middle, the snowpack is weak in some cases. The old snowpack consists of faceted crystals.
The snowpack will be generally subject to considerable local variations. Only a small amount of snow is lying for the time of year in all altitude zones.

Low avalanche danger will prevail.
Individual avalanche prone locations for dry avalanches are to be found in particular on very steep shady slopes above approximately 2000 m and adjacent to ridgelines. They are rather rare and are clearly recognisable to the trained eye.
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.
