Fresh wind slabs represent the main danger. Weak layers in the lower part of the snowpack necessitate caution.
Fresh wind slabs can be released even by a single winter sport participant in all aspects above the tree line. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. At elevated altitudes the avalanche prone locations will become more prevalent. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. As a consequence of the storm force to violent northerly wind individual natural avalanches are possible. Avalanches are medium-sized. They can in isolated cases penetrate deep layers and reach dangerously large size. Caution is to be exercised in particular on very steep northwest, north and east facing slopes above approximately 2200 m.
On very steep grassy slopes individual gliding avalanches are possible, but they will be mostly small.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
As a consequence of snowfall and the storm force wind, fresh snow drift accumulations formed during the last few days. In some regions 5 to 15 cm of snow, and even more in some localities, will fall until the evening. As a consequence of the stormy weather the wind slabs will increase in size once again on Tuesday. The various wind slabs have bonded poorly together. The fresh and somewhat older wind slabs are lying on top of a weakly bonded old snowpack in particular on northwest to north to southeast facing aspects. The snowpack will be subject to considerable local variations.
Tendency
Fresh wind slabs represent the main danger. Weak layers in the old snowpack necessitate caution.

As a consequence of snowfall and the storm force wind, fresh snow drift accumulations formed during the last few days. As a consequence of the stormy weather these will increase in size additionally on Tuesday. The fresh and somewhat older wind slabs are lying on top of a weakly bonded old snowpack in particular on west to north to southeast facing aspects. The various wind slabs have bonded poorly with each other and the old snowpack.
The snowpack will be subject to considerable local variations.

The amount of snow is subject to significant local variations. Fresh wind slabs require caution.
More recent wind slabs can be released by a single winter sport participant in some cases in all aspects above the tree line. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. Individual avalanche prone locations are to be found also in areas close to the tree line. In regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are a little more prevalent. 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. Mostly avalanches are rather small.
In the south the avalanche situation is more favourable. The avalanche prone locations are rather rare and are easy to recognise.
Snowpack
dp.6: cold, loose snow and wind
Little snow will fall. The wind will be storm force. Fresh wind slabs are lying on soft layers at elevated altitudes. The snowpack will be generally subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.
Tendency
Fresh wind slabs must be evaluated with care and prudence.
