High avalanche danger will prevail. The off-piste conditions are dangerous.
The large quantity of fresh snow and the extensive wind slabs are very prone to triggering. The avalanche prone locations are to be found in all aspects above the tree line. As a consequence of new snow and strong wind natural avalanches are to be expected, even large ones. Avalanches can in isolated cases penetrate near-ground layers of the snowpack. This applies above approximately 2200 m.
Midday and afternoon: With the end of the precipitation, the natural activity of slab avalanches will gradually decrease. On extremely steep sunny slopes dry loose snow avalanches are possible. In the event of prolonged bright spells this applies. Gradual decrease in avalanche danger.
An increasing number of small and medium-sized gliding avalanches are to be expected on steep grassy slopes. They can be released at any time of day or night.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Over a wide area 40 to 60 cm of snow has fallen since Saturday. 20 to 30 cm of snow, and even more in some localities, will fall until the evening. The wind will be strong at times. The various wind slabs have bonded poorly with each other and the old snowpack. Isolated avalanche prone weak layers exist in the bottom section of the old snowpack above approximately 2200 m.
Tendency
As a consequence of low temperatures the snowpack can settle hardly at all. The snowpack remains prone to triggering. Backcountry touring calls for caution and restraint.
The fresh wind slabs can be released even by a single winter sport participant above the tree line. Individual avalanche prone locations are to be found also in areas close to the tree line. Such avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. The prevalence of the avalanche prone locations will increase with altitude. Shooting cracks when stepping on the snowpack can indicate the danger. Avalanches can reach medium size.
On steep grassy slopes gliding avalanches are possible, even medium-sized ones. Caution is to be exercised in areas with glide cracks.
Snowpack

Over a wide area 15 to 30 cm of snow has fallen since Saturday. 10 to 20 cm of snow, and even more in some localities, will fall until the evening. As a consequence of new snow and a strong wind from northerly directions, further wind slabs will form. The various wind slabs have bonded poorly with each other and the old snowpack. Faceted weak layers exist in the bottom section of the old snowpack above approximately 2200 m.
Tendency
Gradual decrease in danger of dry avalanches.

Individual avalanche prone locations are to be found also in areas close to the tree line. In addition by the early morning some natural avalanches are to be expected. With the end of the precipitation, the natural avalanche activity will decrease. Avalanches can in some cases penetrate near-ground layers of the snowpack and reach large size.

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.

Wind slabs represent the main danger.
The fresh wind slabs are clearly recognisable to the trained eye. They can be released easily by a single winter sport participant in all aspects above the tree line. Mostly the avalanches are small but easily released. 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 danger is a little higher. In some cases the avalanches in these loacations are medium-sized. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Caution is to be exercised in particular in gullies and bowls in high Alpine regions in all aspects.
Snowpack

From a snow sport perspective, in most cases insufficient snow is lying. The snowpack will be generally subject to considerable local variations. Over a wide area various wind slab layers are lying on a hard crust. As a consequence of the sometimes storm force wind these will increase in size additionally on Tuesday.

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.
