New snow
- Above treeline
The number and extent of avalanche prone locations increase with altitude.
The number and extent of avalanche prone locations increase with altitude.
The avalanche risk is considerable above the tree line and moderate below it. The main problem is new fallen snow. The avalanche prone locations are in steep terrain adjacent to ridgelines in all aspects, behind slope discontinuities and in gullies and bowls. Slab and loose snow avalanches can detach themselves and reach medium size. Occasionally, avalanches with a large additional load, for example from a superficial avalanche, can be triggered in deeper weak layers and become large.
In the Allgäu in particular, gliding avalanches can detach themselves on previously aperic, very steep meadow slopes. They can reach medium size.
Between 40 and 60 cm of new fallen snow has fallen, locally even more, especially in the western regions. Large snowdrift accumulations have formed, some of which are covered by the new fallen snow. Another few centimetres will be added overnight. The snowfall will be accompanied by moderate, sometimes strong winds from northerly directions. The new and wind slab snow is lying on soft snow and is prone to triggering. Weak layers prone to triggering and graupel are embedded within the new snow pact. At high altitudes, weak layers of faceted crystals can be found in the upper part of the old snowpack. The underlying old snowpack is generally well stabilised. In the regions rich in fresh snow, sliding movements are possible on smooth, wet ground.
The avalanche danger is slowly decreasing.
