Be aware of the problem of old snow at high altitudes
The avalanche danger is moderate above 2200 metres and low below. The main problem is old snow. In the north-west to north-east sector, slab avalanches can be triggered in some places by even a small additional load. Avalanches can occasionally be of medium size if the snow thickness is sufficient. Small sliding snow avalanches can occur spontaneously above 1800 metres.
The snow surface is often still loose at high altitudes. In the central part of the snowpack, weak layers of angular crystals have formed between the fresh snow packs of the past week. In small areas, surface frost may also have been snowed in. On the sunny side, the snow cover has settled well up to high altitudes and is partly sliding on steep, smooth slopes.
On Sunday, it will be sunny until midday and visibility will be very good. In the afternoon, increasingly dense clouds will gather. The wind will be light at best. At 2000 metres it will be -1 to +2 degrees, at 3000 metres around -5 degrees. In the night to Monday and until Monday morning it will rain and snow a little from dense clouds (snow line around 1100 m). A few centimetres of fresh snow will accumulate in the northern Alps, where clouds will dominate. In the Tauern region, the precipitation will remain unproductive and the sun will shine in the afternoon. The wind will be mostly light. At 2000 m -4 to 0 degrees, at 3000 m around -8 degrees.
The problem of old snow at altitude remains.
