Generally favorable conditions. Caution urged on steep shady slopes.
Isolated avalanches can still be triggered by winter sports enthusiasts, particularly in little-skied backcountry terrain where the surface is not capable of bearing loads. Danger zones occur especially in spots where the snow is relatively shallow, and in transitions from shallow to deep snow. Avalanches can trigger down to deeper layers inside the snowpack and grow to large size. A cautious route selection and maintaining safety distances between tourers on ascents and descents are recommended. On hard-frozen steep slopes, the danger of sliding and falling require special caution. During the course of the day, likelihood of naturally triggered small wet-snow avalanches triggering increases somewhat on sunny, steep slopes.
Snowpack
The snowpack following a night of clear skies and good longwave outgoing radiation is predominantly well consolidated, mostly with a melt-freeze crust capable of bearing loads, which then softens up during the daytime hours on sunny days slopes. On north-facing slopes, a rain crust extenty regionally up to 2300-2500m. The mid-sedtion of the snowpack consists of well-settled, consolidated layers where shady slopes at high altitudes are blanketed over by large-sized cup-shaped crystals.
Tendency
No significant change is anticipated. The persistent weak layer problem on shady high-altitude slopes will persist. Frequency of danger zones is gradually receding.

Be aware of the persistent weak layer problem!
The avalanche risk is predominantly moderate above 1800 metres. There are still avalanche prone locations on shady slopes in steep terrain. Here and at the transition from little to more snow, isolated slab avalanches can be triggered by mostly large additional loads. Individual spontaneous wet snow avalanches are possible from unloaded steep slopes.
Snowpack
The snowpack firms overnight, initially crust can form on the surface, but is otherwise moist up to high altitudes, and also wet on sunny slopes. It then loses firmness with incoming radiation. The snow base, fundament remains high up and weakened on the shady slopes due to the kinetic metamorphism. Low and sunny slopes in the middle are bare.
Tendency
Little change.

Caution on the northern sides of the high altitudes at transition areas from little to much snow.
The avalanche risk is moderate above 1800 metres and low below that. Persistent weak layers are the main problem. On very steep slopes in the north, large slab avalanches with a high additional load, such as a cornice break, can be triggered in isolated cases.
At medium altitudes, individual small to medium gliding avalanches are also possible on slopes with smooth ground. Smaller loose snow avalanches can detach themselves from steep terrain interspersed with rocks.
Snowpack
On shady slopes at higher altitudes, weak layers of faceted crystals can be found deep in the snowpack. These are usually covered by compact or crusted can form layers of snow. Outgoing longwave radiation at night is limited and the snow surface is only partially crusted can form in the morning. As it warms up during the day, the snow softens, especially in the sun, and loses its bond. At higher altitudes, faceted crystals have formed on the north side under a thin, surface melt-freeze crust. Towards the ground, the snowpack is wet in the middle layers. On the south side and at lower altitudes, the ground is becoming more and more pale.
Tendency
The avalanche danger hardly changes.

Weak layers persist deep in the snowpack
The problem is the weak layers in the snowpack, which are deeper in the snowpack. 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
The snowpack freezes at night, then hardens during the day, especially in the mid-mountains on Sunny slopes. The crust strengthens and becomes thicker. This process will be less pronounced today. The snow has settled and is already well consolidated, especially on the Sunny slopes. The snow layers have stuck together. Several weak layers of shreds and flaked grains are appearing deep below the surface in the old snow cover.
Tendency
It will clear up on Tuesday. Faster in the high alpine regions than in the mid mountains. There will be no major warming. The danger of avalanches will remain similar.

Note the persistent weak layer
The avalanche risk is moderate from around 2000 metres and low below. In a few places, medium to large slab avalanches can be triggered by individuals, especially in the aspects from west to north to east. Danger areas are often difficult to recognise and a defensive choice of route is still advised. Take particular care at the transitions from little to more snow.
Wet snow avalanches are possible on the sunny slopes as the snowpack softens. These usually remain small, but at very high to high alpine altitudes (from around 2600 m) they can penetrate into weak layers close to the ground. The likelihood of gliding avalanches increases somewhat due to the greatly reduced outgoing longwave radiation at night.
Snowpack
The snowpack can cool down overnight and form at least a thin melt-freeze crust. On sunny slopes, this softens during the day and the snowpack is damp or wet up to high altitudes. In shady high altitudes, some soft, faceted snow can still be found on the surface, some of which has already crusted can form. Below this lies a now predominantly well-set and connected sequence of compact drift snow layers. The connection at the transition to the old snow foundation, which consists mainly of deep rime, is still poor. The deep and sunny middle layers are largely snowed out.
Tendency
On Wednesday, a slight deterioration in the weather with spring clouds and unproductive precipitation.

Weak persistent layer is still the main problem
The avalanche risk is moderate above 1800 metres and low below. There is still a persistent weak layer problem in the extended northern sector. Medium-sized slab avalanches can still be triggered by people in mainly steep gullies and bowls. The avalanche prone locations are usually difficult to recognise and are often located in transition areas from little to much snow.
On the sunny slopes, the softened, barely stabilised snowpack can trigger wet snow avalanches.
Snowpack
Depending on the degree of cloud cover overnight and the wind influence of the last few hours, a surface crust of varying thickness can form, which softens during the day on the sunny slopes and the snowpack becomes increasingly damp or wet. On shady slopes at higher altitudes there are still areas with a soft (faceted) snow surface, but often the layer is already hard here too. Below this, there are still responsive weak layers in the form of faceted crystals in the area of crusts or frost that is still snowed in. In addition, the foundation consisting of floating snow (deep rime) continues to weaken the snowpack (partly also on the south side). Medium (sunny slopes) and low altitudes are largely free of snow.
Tendency
Weak disturbances on Wednesday, with some precipitation in places, it will remain mild. No significant change in the avalanche risk is expected.

Isolated wet snow avalanches!
The avalanche risk is predominantly low. Sporadic spontaneous wet snow avalanches are possible from unloaded steep slopes. There are still isolated avalanche prone locations on shady slopes in steep terrain where slab avalanches can be triggered by large additional loads.
Snowpack
The snowpack hardly firmnesses overnight with increasing cloud cover, is only partially crusted can form on the surface, but is otherwise moist or wet up to high altitudes. The snow base, fundament is high and occasionally weakened on shady slopes due to the kinetic metamorphism. Low and increasingly middle elevations are bare.
Tendency
Little change.
Danger level
Favorable conditions will continue
Avalanche danger is predominantly low. Isolated danger zones occur particularly in extremely steep terrain. Small avalanche triggerings are mostly possible in relatively shallow-snow areas and in transitions from shallow to deep snow. Beware the danger of sliding and falling on hard-frozen steep slopes. During the course of the day, likelihood of naturally triggered small-sized avalanches increases somewhat on sun-basked, very steep slopes.
Snowpack
Following a night of clear skies and good longwave outgoing radiation, the snowpack is well consolidated and stable. Generally there is a melt-freeze crust capable of bearing loads, which softens up during the daytime hours, particularly at low altitudes and on sunny slopes. No further triggerings in older weak layers of the snowpack were registered in recent days at the Avalanche Warning Service.

Continuing favorable conditions, no significant change anticipated

Note the persistent weak layer problem in the extended northern sector!
The avalanche risk is low. Nevertheless, there is still a persistent weak layer problem in the extended northern sector. Occasionally, mainly in very steep gullies and bowls, slab avalanches can be triggered by people. The avalanche prone locations are usually difficult to recognise and are often located in transition areas from a little to a lot of snow.
On the sunny slopes, the softened, barely stabilised snowpack can trigger small wet snow avalanches.

Avalanche Problem
Wet snow
There is a risk of falling on hard snow surfaces.
The avalanche risk is low. Wet snow is the main problem. Occasionally, small loose snow avalanches can detach themselves from the steep terrain interspersed with rocks. Individual, smaller gliding avalanches are possible on very steep slopes with smooth ground that have not yet been discharged.
On shady, very steep slopes at higher altitudes, medium slab avalanches can also be triggered in isolated cases with a large additional load. This is particularly the case at transitions from a little to a lot of snow.
Snowpack
The snowpack is soaked up to high altitudes and is often wet towards the ground. Overnight outgoing longwave radiation is limited and the snow surface is only partially crusted can form in the morning. As it warms up during the day, the snow softens, especially in the sun, and loses its bond. Occasionally, weak layers of faceted crystals can be found deep in the snowpack on shady slopes adjacent to the higher peaks and summits. They are covered by compact or crusted can form layers of snow. On the south side and at lower altitudes, the ground is becoming increasingly paler.
Tendency

Wet snow
Low risk of isolated wet snow avalanches
The avalanche risk is low. Small wet snow avalanches are possible on the few sunny slopes that have not yet been discharged.
In addition, small snow slabs can still be triggered in exceptional cases in the entrance areas of steep gullies on the shady slopes with a large additional load. In addition to the risk of burial, attention should be paid to the risk of being swept away and falling on icy surfaces.
Snowpack
The snowpack is moist to wet and well settled right up to the summit areas. Only a thin melt-freeze crust forms overnight. In the higher, on shady slopes, there are still weak layers of large faceted crystals in the lower part of the snowpack, especially close to the ground. Deep and sunny middle layers are covered with snow.
Tendency
No significant change in avalanche danger.
Danger level
Low avalanche risk - note the risk of falling in steep gullies.
The avalanche risk is low. Small slab avalanches can occasionally be triggered in persistent weak layers on shady slopes. Very occasionally, small wet loose snow slides are still possible from steep gullies. In general, the risk of falling and injury clearly outweighs the risk of burial, especially in partly icy steep gullies and bowls.
Snowpack
On the sunny slopes, the clouds overnight mean that hardly any stable melt-freeze crust forms and the snow softens quickly in the morning. In shady areas, the melt-freeze crust of the past few days persists well into the afternoon. In summit areas, the snow surface is hard and sometimes icy due to wind and rain. In gullies and bowls, the wind slab is well stabilised. Faceted crystals are weakening the snow base, fundament in the northern sector. There is little snow below 1400 metres and below 1600 metres on sunny slopes.
Tendency
The avalanche risk remains low. On Wednesday, the clouds will increase again during the daytime changes. Scattered rain showers are possible towards the evening.
