Wet snow is the main problem, be careful in the rain
The avalanche risk is already considerable below around 2800 m in the morning. Wet slab avalanches and loose snow avalanches are possible in all aspects on slopes that have not yet been discharged or are to be expected in the event of rain. The avalanches can occur spontaneously or be triggered by individuals. They can become large with the accumulation of wet snow and tearing through the persistent weak layer in some places. Caution should also be exercised in the open run-out areas of trenches. There are isolated signs of sliding snow activity.
In a few places above 2200 m, weak layers can also be disturbed directly in the persistent weak layer, especially on west, north and east-facing slopes, and also south-facing slopes in the high Alps. Snow slabs in the persistent weak layer can be medium in size, and large if they break through into the floating snow near the ground. The avalanche prone locations are difficult to recognise.
Strong southerly föhn winds deposit small pillows of wind drifted snow in high gullies and bowls. Be careful at the transition from a little to a lot of snow.
Snowpack
It is only slightly colder than before. Nevertheless, the snowpack has difficulty cooling down overnight and is already softened in the morning. Beneath it lies well-settled snow from the last periods of precipitation, but softer layers are embedded, especially at higher altitudes, which allow breaks near the surface. On shady slopes from around 2200 metres, there are still prone to triggering weak layers of angular forms and deep rime in the old snowpack close to the ground. The snowpack becomes moist to wet up to high altitudes during daytime changes at the latest. Low and sunny slopes are snowed out.
Tendency
In the course of Tuesday night, the Föhn will break down, followed by light precipitation with a snowfall level of around 2200 metres. Rain and reduced outgoing longwave radiation at night weaken the snowpack.

Wet snow is the main problem
The avalanche risk is moderate. Wet loose snow and slab avalanches are already possible in the morning on slopes that have not yet been discharged in all aspects and altitudes. The avalanches can occur spontaneously or be triggered by winter sports. They usually remain medium in size, but with the accumulation of wet snow and tearing through to weak layers close to the ground, large avalanches are conceivable in exceptional cases. Caution should also be exercised in the apery outlets of trenches. There are isolated signs of sliding snow activity.
In a few places above 2200 m in the extended northern sector, weak layers directly in the persistent weak layer can still be disturbed by individuals and lead to medium-sized slab avalanches.
Snowpack
It is only slightly colder than before. Despite this, the snowpack has difficulty cooling down overnight and is already softened in the morning. Underneath is well-settled snow from the last periods of precipitation. On shady slopes above around 2200 metres, there are still prone to triggering weak layers of angular forms and deep rime in the old snowpack close to the ground. The snowpack becomes moist to wet up to high altitudes during daytime changes at the latest. Low and sunny slopes are snowed out.

Wet snow
Small wet snow avalanches in snowy places
The avalanche risk is low. Small, spontaneous wet snow slides can occur from slopes that have not yet been discharged in all aspects. Wet snow slides triggered by winter sports increase the risk of entrainment in the fall terrain.
Snowpack
The outgoing longwave radiation at night is poor and the snow cover remains largely moistened to isothermal due to the warmth. In places, you can still find small pillows of wind drifted snow adjacent to ridgelines, but most of the terrain is already tapped out.
Tendency
Gradual reduction of the avalanche risk due to melting and raining away of the remaining snow.
