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.

1300m
Gliding snow

Minor wet snow avalanches possible due to thawing
The snowpack of the last snowfall has become unstable as the weather warms up. The danger of wet snow avalanches has increased, especially on extreme terrain. On grassy slopes, gliding avalanches will be possible. This only applies to the highest peaks where there is some more snow.
Snowpack
dp.4: cold following warm / warm following cold
As the weather warms up, much of the snow from the last snowfall has been cleared away. The snow line is at around 1200 m. At higher altitudes, the snow of the last snowfall has become much heavier and is being transformed more quickly.
Tendency
Typical spring conditions are expected over the next few days.
The snowpack will freeze overnight, but during the day, with sunshine and high temperatures, the snow will change and melt more quickly.
