Persistent weak layers
- Above 1,800 m
Be aware of the persistent weak layer problem at high altitudes!
Be aware of the persistent weak layer problem at high altitudes!
The avalanche danger is rated as moderate above 1800 metres. Wet loose snow avalanches from slopes that have not yet been discharged are still possible. There is still a persistent weak layer problem in the northern sector: in very steep gullies and bowls on the shady slopes, triggering of dry slab avalanches is possible with large additional loads.
During the night, the firmness of the snowpack surface increases again briefly. The snowpack has settled. Up to the high altitudes, the snowpack became wet or moist depending on the aspect. On the northern slopes of the higher elevations, the kinetic metamorphism (persistent weak layer problem) continues to weaken the snowpack.
The evening will bring a few showers in the western mountains of Upper Styria, then after midnight it will be dry everywhere with a few patches of cloud moving through. Wednesday starts with residual clouds, with some high fog over the valleys. Very soon, however, very sunny weather will prevail for a few hours before more cumulus clouds form again in the afternoon. Visibility will deteriorate in places and some rain, snow or sleet showers will be possible, especially in the eastern mountains.
High pressure will bring bright sunny mountain weather for a few days from Thursday. Please note the daytime changes in avalanche risk.
