Combined wet and persistent weak layer problem

Combined wet and persistent weak layer problem

The avalanche risk is considerable above 2000 m and moderate below. In a few places, medium to large dry slab avalanches can be triggered by individuals (even from a distance), especially on shady slopes. Danger areas are difficult to recognise away from obvious pillows of wind drifted snow, which is why caution and a defensive choice of route is still advised. In addition, large spontaneous wet snow avalanches and avalanches triggered by people can occur in all aspects. There is a low level of sliding snow activity.

On the sunny slopes, the snowpack briefly carries a (more or less load-bearing) melt-freeze crust, below which it is moist up to high altitudes. There is still soft, dry snow on the shady slopes. The new and wind slab snow of the last week has settled and is often well connected to each other. However, the connection to the angular persistent weak layer below is still poor.

The night will start clear at first, but clouds will increase from the west. There may be light showers in the second half of the night, snow from around 1800 metres. It will remain dry in Lungau. On Sunday, the sky will often be overcast and short showers may fall, from about 1700 m as snow. In Lungau it will remain dry and some sunshine is possible. The wind will remain weak. Around 0 degrees at 2000 metres.

The persistent weak layer problem continues to make the situation tense and difficult to calculate in the terrain. Note slight daytime changes on Tuesday.
