The avalanche danger is rated as moderate above the tree line. The stormy wind has formed fresh wind slabs that are easily recognisable. Above the tree line, the fresh wind slab can easily be triggered as a snow slab. Typically, medium avalanches are expected to be triggered. The avalanche prone locations are adjacent to ridgelines as well as distant from ridgelines and in steep gullies and bowls. Loose snow avalanches are possible from steep rocky and rugged terrain.
The strong to gale-force winds have worked the new fallen snow (up to 60 cm). The wind slab is usually quite hard. Weak layers are to be expected within the drift snow layer. The old snowpack is mostly hard and close to the ground the snowpack is weakened by floating snow.
The clouds over the Styrian mountains will increase again in the coming night, with light snowfall starting north of the main Alpine ridge in the early hours of the morning. On Sunday, dense clouds will persist and it will snow a little, especially from the northern slopes up to the Rax. Visibility will also be very limited due to low cloud bases. The temperature at an altitude of 1500 metres will be between -4 and -1 degrees. Strong winds with gusts of around 60 km/h from the west. No significant increase in fresh snow is expected.
With a northerly high-altitude current, it will remain cloudy and often snowy along the northern side of the Alps throughout Holy Week. Although conditions are dry south of the main Alpine ridge, it is usually cloudy and windy here too.
