Persistent weak layer problem in the high altitudes!
Persistent weak layer problem in the high altitudes!
The avalanche risk is low. There are still avalanche prone locations due to the constant problem of old snow, especially in the high areas on the north and shady slopes. In places, slab avalanches can be triggered by just one person in steep terrain. Avalanche prone locations are mainly adjacent to ridgelines and behind terrain edges. These are somewhat covered and therefore difficult to recognise.
The snow base, fundament contains faceted crystals without bonds, which are mainly transformed on the north and on shady slopes. The old snowpack, weakened as a result, is often hard on the surface and covered by a thin settled layer. Only in very exposed areas could there be some older wind slab on a small scale. In general, there is little snow, which is very unevenly distributed.
On Monday, visibility on the edge of the Alps will initially be limited by patches of high fog. At higher altitudes in the Limestone Alps, the sky will be mostly cloudless from early in the morning and visibility will be very good. During the daytime changes, the sun will also prevail at lower altitudes. The wind is mostly weak. During the daytime changes, the temperature will rise from -3 to 1 degree at 1500 metres and from -5 to -1 degree at 2000 metres. Tuesday will be sunny at times. But there will also be widespread clouds. The wind will be moderate around the south-east with some strong gusts. Up to 5 degrees at 1500 m and up to 3 degrees at 2000 m.
No significant change.
