Persistent weak layers
- Above 1,800 m
Moderate avalanche danger at high altitudes!
Moderate avalanche danger at high altitudes!
The avalanche danger is rated as "moderate" above 1800 metres. Avalanche prone locations are older snowdrift accumulations, which can be triggered as slab avalanches, especially in shady areas of the high altitudes, due to large additional loads, occasionally also due to small additional loads. Mainly medium-sized avalanches are expected. Small wet snow slides and occasional gliding avalanches are to be expected on sunny slopes.
The wind slab of the past few days has settled and is hardly prone to triggering. However, a weak layer has formed in the transition to the mostly stable old snow foundation in shady high areas. On the sunny slopes, the snowpack is becoming moist and can begin to glide snow on a smooth surface.
Friday night will be mainly cloudy. The weather will improve on Good Friday and sunny weather will prevail during the morning. The wind will blow briskly, in the east of the Styrian mountains also strongly from the north-west. The temperature at 2000 metres above sea level will rise from -4 to -1 degrees during the day.
On Saturday, a weak disturbance from the north will once again cause overcast skies and the temperature will rise significantly. The wet and sliding snow problems will increase.
