Highly prone to triggering wind slab snow at the top, spontaneous wet snow avalanches at the bottom
The avalanche risk is high above the tree line (level 4) and considerable below. Individual naturally triggered avalanches are still possible and in many places medium and sometimes large slab avalanches can easily be triggered by individuals (even from a distance). All aspects are affected, but increasingly north and east-facing steep terrain. Danger areas are not easy to recognise everywhere, which is why caution and a defensive choice of route is still advised. This applies in particular in the area of the tree line and in forest aisles. Wet loose snow and gliding avalanches are possible at low and medium altitudes due to heavy rainfall. These usually remain medium-sized, but occasionally the entire snowpack can slide off on very steep, unstructured terrain.
Snowpack
Up to half a metre of fresh new or wind slab snow lies on top of several more thick layers of wind-blown new fallen snow from the last few days. Especially at the beginning, snow fell with less wind and at colder temperatures, which is why soft layers are also embedded. These overlay somewhat older wind slab snow, which in turn lies on an unfavourable base of faceted crystals and deep rime. In wind-protected areas, some surface hoar has also been snowed in. Up to around 1800 metres, the snowpack was soaked by heavy rain. Fractures primarily occur between the last snow packs, but can also penetrate through to the old snow foundation, which is usually completely transformed. At low and medium altitudes, heat and rainfall put a strain on the snowpack.
Tendency
Precipitation will set in again, with rain falling at times up to around 2000 metres on Tuesday. Above that, 20 to 40 cm will fall. The avalanche situation remains tense.

Naturally triggered avalanches still expected
Dangerous avalanche situation persists apart from heavily skied terrain
Large amounts of fresh snow and drifts from last week blanket a weak old snowpack. Avalanches can easily be triggered by one single winter sports enthusiast in all aspects, especially in little-skied terrain. Danger zones increase with ascending altitude, occur widespread in terrain near to and distant from ridgelines. Caution urged in transitions from shallow to deep snow, for example, at entries into gullies and bowls. Remote triggerings are possible. Avalanches can be large-sized and plummet over flattish passages. As a result of renewed rainfall and the snowpack becoming ever wetter, wet slab avalanches can be expected at low and intermediate altitudes. If these fracture to deeper down layers of the snowpack, they can in isolated cases grow to large size. On steep grass-covered slopes, glide-snow avalanches can trigger. Zones with glide cracks should under all circumstances be avoided.
Snowpack
During the night there was 20mm of rainfall registered in the northern regions of highest precipitation. During the daytime, another 10mm can be added to that. Above 2000m, about 15 cm of fresh snow, accompanied by strong-velocity winds. The large amounts of fresh snow from the last few days have been repeatedly transported in varying directions, snowdrift accumulations are poorly bonded with the old snowpack. Weak layers are widely prevalent in the lower part of the snowpack. The extraordinary avalanche activity last week confirms just how prone to triggering the weak layer is. This layer persists apart from heavily skied zones and in starting zones which have not yet discharged. At low and intermediate altitudes the snowpack is thoroughly wet. Even at higher altitudes there are breakable crusts, particularly in areas exposed to the sun.
Tendency
Avalanche danger is gradually diminishing, but the situation for winter sports enthusiasts remains extremely treacherous in little-skied terrain

Avalanche prone locations due to easily triggered wind slabs and naturally triggered avalanches!
Above the tree line there is still a considerable avalanche risk, below it is moderate. Above the tree line in particular, there are prone-to-triggering drift snow packs that can occur in all aspects. Medium to sometimes large slab avalanches can be triggered by even a small additional load. Steep terrain should therefore be avoided. Avalanche prone locations are mainly adjacent to ridgelines, but also distant from ridgelines, at terrain transitions and in the entrance areas of bowls and gullies. Remote triggering cannot be ruled out. In transition areas where there is too little snow, weak layers in foundations (persistent weak layer problem) could be addressed. Below the snowfall level, spontaneous damp to wet small to medium loose snow avalanches from undischarged steep terrain are to be expected.

Snowpack
With the unstable weather, snowfall of varying intensity and strong to stormy winds from changing directions, extensive snowdrift accumulations have formed, which contain weak layers, do not bond well with the old snowpack and lie on a weak foundation. At high altitudes, the snow base, fundament still contains faceted crystals without binding, especially on the north and shady slopes, and partly floating snow. Up to the middle elevations, the snowpack was at least superficially moist due to rain, below that it is soaked to wet.

Snowfall again with strong to stormy winds, fresh wind slab above the tree line and rain in some places up to mid-altitude. The avalanche situation remains precarious.

Increase in avalanche danger to level 4!
The avalanche danger is assessed as high (level 4) from 1800 metres upwards. During the intense precipitation in combination with storms (transport!), spontaneous discharges are expected at high altitudes. At lower elevations, spontaneous wet snow avalanches and gliding avalanches on steep meadow slopes are to be expected. Exposed transportation routes may be affected.
In the touring area, it is difficult to assess the avalanche situation in the prevailing weather conditions. Slab avalanches can be triggered on many steep slopes with little additional load.
Snowpack
New fallen snow and strong winds from the west to northwest have led to extensive transported snow and in some cases massive snowdrift accumulations in the aspects from northeast to east to south in the past few days. In addition, 30 to 50 cm of new fallen snow is expected in stormy conditions. The connection between the wind slab and the old snowpack will not be sufficient. There are still weak layers in the transition to the persistent weak layer. In the shady areas, the snowpack is weakened by faceted crystals and floating snow.
Tendency
High pressure influence and massive warming at altitude from Wednesday lunchtime. The zero-degree level will rise to 3000 metres by Wednesday evening. The high avalanche risk remains.

Avalanches release themselves.
The avalanche risk is high above 2000 metres and considerable below that. The main problem is the predicted new fallen snow. Many self-triggering dry slab avalanches are to be expected due to the additional load of the new fallen snow. These can become large at high altitudes. In addition, individual winter sports enthusiasts can trigger avalanches, especially on steep slopes where the snow is bonded by wind. From extremely steep, rocky terrain, the new fallen snow is released in the form of loose snow avalanches.
Wet snow is also problematic. Due to the rainfall, gliding avalanches can be expected from very steep terrain with a smooth surface at medium altitudes and wet loose snow avalanches from steep terrain interspersed with rocks. Wet snow avalanches are to be expected on all slopes that have not yet been discharged up to approx. 1800 m and can reach medium size. Open snow mouths indicate avalanche prone locations. Exposed transportation routes can be hit by wet avalanches.
Snowpack
Snowdrift accumulations can be found in all aspects. At higher altitudes, they often lie on graupel, old surface hoar, soft intermediate layers or in the area of thin crusts on faceted crystals. Above 1800 m, there are weak layers of faceted crystals in the snowpack on shady slopes. Up to around 1800 m, the snowpack becomes soaked through rainfall. At medium altitudes, the base of the snowpack is usually wet.
Tendency
The avalanche situation remains tense.

Wet snow problem at the bottom, wind slab problem at the top
The avalanche risk is considerable. The main problem is wet snow. Below 1800 m, gliding avalanches on steep slopes with smooth ground, such as on mountain meadows, in gappy deciduous forests or on rock slabs, release themselves. Staying in areas below glide cracks should be avoided. Wet loose snow avalanches release on slopes that have not yet been discharged, especially in extremely steep terrain. Wet avalanches can reach medium size and hit exposed transportation routes.
In addition, wind slabs above 1600 m must be taken into account. Medium-sized slab avalanches can be triggered on steep slopes of all aspects by low additional loads.
Snowpack
Snow falls at higher altitudes with a changing snow line. At medium altitudes, it mainly rains. Here the snowpack is particularly moist on the south side and in the forest down to the ground, below 1500 metres it is completely soaked. With strong westerly winds, the new fallen snow at higher elevations will be extensively transported and will be deposited prone to triggering on the already thick drift snow packs of the last few days. In places, these are lying on graupel or old surface hoar. Above 1800 m, weak layers of faceted crystals can be found on shady slopes at the base of the snowpack.

Rainfall leading to wet-snow avalanches
Due to heavy rain impact, increasingly frequent medium-sized wet-snow avalanches can be expected in steep terrain. Where there is lots of snow on the ground, these releases can grow to large size. On steep grass-covered slopes, glide-snow avalanches can occur. Zones with glide cracks on the surface should under all circumstances be avoided. At high altitudes, avalanches can be triggered even by one single winter sports enthusiasts, particular from freshly generated snowdrift accumulations. Danger zones occur in steep ridgeline terrain and behind abrupt changes in the terrain. Particularly on very steep shady slopes above 1800m, avalanches can fracture down to deeper-down layers inside the snowpack and then grow to large size. Whumpf noises and fractures which appear when treading upon the snowpack are alarm signals.
Snowpack
About 20mm of rain was registered during the nocturnal hours. During the daytime another 15mm can be added to that. Above 2000m, about 15cm of fresh snow, accompanied by strong-velocity winds. At high altitudes, fresh and older snowdrift accumulations in all aspects are only moderately to poorly bonded with the generally weak old snowpac. On shady slopes there are weak layers in the lower part of the snowpack.
Tendency
Wet-snow activity will decrease when the precipitation ceases. Then a high-pressure front will diminish avalanche danger also at high altitudes.

Considerable avalanche danger!
The avalanche danger is predominantly categorised as considerable. Due to some intense snowfall and wind, there will be additional wind slab avalanches in the higher elevations. The triggering of medium to rarely large slab avalanches is possible to likely on some steep slopes due to low additional loads. Due to the local old snow problem, the snowpack can tear through to deeper layers. Above the tree line, medium to sometimes large spontaneous slab avalanches are possible. Spontaneous wet snow avalanches are to be expected below the snowfall level due to heavy rainfall.

Prone to triggering wind slab snow at the top, spontaneous wet snow avalanches at the bottom
The avalanche risk is considerable. At low and medium altitudes, warmth and heavy rainfall put a strain on the snowpack, while fresh wind slab is formed at higher altitudes. Medium to large slab avalanches can be triggered in some places by a single person. Danger areas are located at the transition from little to more snow and generally next to blown-off areas as well as in the entrance areas to gullies and bowls filled with wind slabs. Caution should also be exercised at the edge of forests and in forest aisles. At low and medium elevations, medium wet loose snow and gliding avalanches are also to be expected.
Snowpack
Rainfall has soaked the snowpack up to altitudes of around 1800 metres. At high altitudes, the new snow cover is inhomogeneous and prone to triggering (harder layers alternate with softer ones) due to repeated wind influences of varying intensity. Where present, the old snow foundation has been completely transformed. Fractures are possible mainly between the last layers of drift snow, but under greater stress, deep-lying faceted layers in the persistent weak layer or the coarse-grained base of deep rime are also affected.

Heavy precipitation sets in again, with intense rain at times up to around 2000 metres on Tuesday. Above that, there is heavy new fallen snow of 30 to 60 cm (mainly Steinberge/Hochkönig/Tennengebirge). The avalanche situation worsens again.

As the weather warms up, the danger of wet snow avalanches has increased. Blowing snow in the high alpine regions!
On Monday, as the weather warmed up, wet snow avalanches and gliding avalanches broke out, mainly on sunny slopes and in the mid-mountains. This danger will decrease slightly temporarily. However, there are still a number of places in the high alpine regions with blowing snow where a small load can trigger a major avalanche. Weak layers in the snowpack are also a problem. If the load exceeds the load-bearing capacity of the deeper Weak layers, a deep and large avalanche can be triggered. There are many such weak layers, especially on axis above the forest.
Snowpack
dp.1: deep persistent weak layer dp.4: cold following warm / warm following cold
The old snow cover is made up of layers of bonded snow that are already somewhat compacted, and which are mostly well connected to each other. Deep below the surface, several weak layers of faceted snow crystals and coarse grains occur in the old snow cover.
This base was covered by 50 to 80 cm of new fallen snow during the last snowfall in the high alpine regions, which has already begun to settle to some extent. The warmer temperatures and sunshine have led to the formation of a more or less distinct Crust. The snow is drying out during the day and freezing at night. The snowpack is also melting in the mid-mountains. This process will be less pronounced on Tuesday due to cloudier weather.
Tendency
It will clear up by Wednesday morning. The snowpack will also frost over the central mountains. Wednesday will be sunny and quite warm. The zero isotherm will rise above 2500 m above altitudes in the afternoon. The danger of Avalanches will increase due to the daily thaw.
