Wind slab

Fresh wind slab in the northern sector!
Fresh wind slab in the northern sector!
The avalanche danger is rated as moderate above the tree line and low below. The main problem is wind slab. The avalanche prone locations are in the terrain adjacent to ridgelines and in the entrance areas of gullies and bowls. The north and east sectors are particularly affected. Triggering of a snow slab is possible with low additional load. The slab can slide to the ground, so medium avalanches cannot be ruled out.
Between 10 and 20 cm of new fallen snow has been added in the last 24 hours. The strong southerly wind has transported the snow to the northern sector. The connection between the wind slab and the old snowpack is not sufficient. The snow base, fundament is weakened by angular shapes on shady slopes (persistent weak layer problem!).
The rain and snowfall will subside before midnight and it will become partly soft in the second half of the night. On Monday, there will still be some residual clouds in the morning, with fog often lingering in the valleys. During the day, increasingly sunny mountain weather will prevail. The temperature at an altitude of 2000 metres will be between -5 and -2 degrees. The temperature at an altitude of 1500 metres is between -4 and 0 degrees. Brisk winds with gusts of around 60 km/h from south to north. The snowfall level is between the valleys and around 600 metres above sea level.
Very sunny again on Tuesday with an increasingly southerly flow. No significant change in the avalanche danger is expected.
