Considerable avalanche danger!

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.

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.

The mountain weather will be windy and changeable on Monday. At first it will rain and snow from dense clouds with snowfall levels around 1700 metres. As the day progresses, the clouds will soften at times with the westerly wind and a few rain and snow showers will pass through from time to time. At high altitudes, the wind will reach speeds of around 70 km/h. Temperatures at 1500 metres will be around 2 degrees, at 2000 metres around -2 degrees. In the second half of Tuesday until midday on Tuesday, there will be snowfall again (around 20 cm, significantly more at higher altitudes) and rain with a snowfall level of around 1200 metres. The precipitation will subside in the afternoon and the initially strong to stormy westerly/north-westerly winds will ease. At 1500 m around -1 degrees and at 2000 m around -4 degrees.

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.
