The avalanche danger is moderate above 2200 metres and low below. Old snow is the main problem. Slab avalanches can be triggered at high altitudes on very steep slopes in the northern exposures, especially with high additional loads. Far-reaching break propagation and thus avalanches of medium size are possible in wind-protected hollows. Otherwise, avalanches usually remain small and the risk of falling must be taken into account.
Individual sliding snow avalanches can spontaneously slide down extremely steep slopes with smooth ground that have not yet been discharged. These are usually small.
Snowpack
At night, the moist snow cover freezes and becomes icy. During the day, it softens again slightly on the sunny side and remains hard on the shaded side. At the highest summits, the snow cover is thinner on the shaded side and is not stable everywhere. Here, the snow underneath the snow cover has an angular structure. In places, the top half metre of snow still has a layer of surface frost that is prone to disruption. Sliding movements still occur occasionally on smooth ground. On the south side, the ground is increasingly pitting in the middle layers.
Tendency
The old snow problem is slowly becoming less acute.

In sunny weather, a small avalanche of packed snow can still occur on steep slopes during the day.
Snow cover is mostly stable. With sunny weather and a relatively warm air mass at high altitudes, some small avalanches of wet snow may still spontaneously occur during the day on steep slopes, but avalanches are unlikely in most areas.
In arid areas above the tree line, weak layers are present in the snow cover. In a few places, a small, clustered avalanche may be triggered under higher loads.
Snowpack
dp.4: cold following warm / warm following cold
The snow cover has already largely melted and stabilised, and a lot of snow has melted on the slopes. In sunny weather, the crust on the slopes strengthens and softens during the day. In the shadier and sheltered areas, especially in the high mountains, the snow cover remains soft and dry. In arid areas, weak layers may be present in the snow cover.
Tendency
Sunny weather will continue at the weekend, with some clouds, especially on Saturday. Temperatures will strengthen on Saturday and weaken again on Sunday. Winds will be light. During the day, the snow cover will become heavier and less stable on the slopes, while the snow on the slopes will melt and melt slowly.
Danger level
Very compact, stable snow cover
The avalanche danger is low. Individual small sliding snow avalanches can occur spontaneously on extremely steep, smooth meadow slopes.
Snowpack
On the shaded side, the snow is compact, hardened and partly icy right up to the higher altitudes. During the day, the remaining snow cover softens on the surface with the sun. The base of the snowpack is often wet. At the highest altitudes, a layer of angular crystals can be found underneath the dominating snow cover. The snowpack is thin overall. The middle layers are increasingly thinning out on the sunny side.
Tendency
The avalanche danger remains low.

Falls and stones are the main danger.
The avalanche danger is low. Small, spontaneous sliding snow avalanches are possible from very steep, as yet undischarged grass mat terrain. Isolated danger spots for mainly small slab avalanches (old snow problem) are possible in shady high altitudes in very steep gullies and hollows.
Snowpack
The snow depth is well below average for the time of year, low elevations are widely bare. The snow surface is hardened and softens during the day at medium altitudes and also at high altitudes on the sunny side. Inside, the snow cover is moist to wet right up to high altitudes. In shady, high and high alpine locations, there are still isolated weak layers of angular crystals in the snowpack.
Tendency
Little change, the avalanche danger remains low.

Gliding snow
Not much snow. Low avalanche danger.
As a result of daytime warming and solar radiation, isolated small-sized glide-snow avalanches are still possible on steep, smooth slopes which have not yet discharged. Glide cracks are signals of potential imminent danger.
Snowpack
During a night of star-studded skies, a breakable-to-capable of bearing loads crust can be generated. During the course of the day, it softens up particularly on sunny slopes and at lower altitudes. South-facing slopes are becoming bare of snow up to high altitudes.

Little change is expected, avalanche danger remains low

Individual sliding snow avalanches, isolated danger spots in old snow
The risk of avalanches is low, the risk of falling or being injured on rocks is greater than the risk of burial.
There are isolated danger spots for slab avalanches at high altitudes (old snow problem), particularly on extremely steep, shady slopes, especially in gullies and hollows. In a few places, mainly small avalanches can be triggered by people.
Small, spontaneous sliding snow avalanches are possible from very steep, undischarged grass mat terrain.
Snowpack
The surface is dominated by (fractured) hardpack or crusts, some of which soften during the day. At shady high altitudes, there are angular crystals within the snowpack near the crusts, which can occasionally serve as a weak layer. Below this, the snow cover is stable and sometimes glides on a smooth surface. Overall, there is very little snow, and on the sunny side, it is snow-free far up.
Tendency
Little change.

Isolated glide-snow avalanches. Isolated danger zones in persistent weak layers
Avalanches can be triggered in the persistent weak layer in isolated cases above about 2400m on very steep shady slopes. These releases usually are small-sized. The risks of injuries from being forced to take a fall outweigh those of being buried in snow masses. As a result of daytime warming and solar radiation, isolated, generally small-sized glide-snow avalanches are still possible on steep slopes which have not yet discharged. Glide cracks are signals of possibly imminent danger.

During a night of star-studded skies, a breakable-to-capable of bearing loads crust can be generated. During the course of the day, it softens up particularly on sunny slopes and at lower altitudes. South-facing slopes are becoming bare of snow up to high altitudes. On shady high-altitude slopes above 2400m, isolated weak layers occur inside the snowpack.
