Slab avalanches, especially in the northern sector

Slab avalanches, especially in the northern sector

The avalanche danger is moderate above 2200 metres and low below. The main problem is old snow. In the sectors from north-west to north to north-east, slab avalanches can be triggered in some places by even a small additional load. Avalanches can break through to deeper weak layers and become medium sized if the snow is thick enough. Small to medium-sized slab avalanches are also possible in fresh drift snow at a few danger spots, especially near the crest. Danger spots can be difficult to recognise in diffuse visibility. Below 2800 m, small sliding snow avalanches can spontaneously occur.

The snow surface is often still loose at high altitudes. In the upper part of the snowpack, fresh snow that has blown over close to the crest can form a weak layer. In the middle part of the snowpack, weak layers of angular crystals have formed between the fresh snow packs of the past week. At high altitudes, angular crystals can also be found at the transition to the compact old snow foundation and occasionally near the ground. On the sunny side, the snow cover has settled well up to high altitudes and can slide off the ground.

After a clear night, it may snow and rain lightly and unproductively at times from dense clouds on Saturday, especially in the northern Alps. Light and unproductive precipitation is also possible from dense clouds in the Hohe Tauern region. The snow line will rise from around 1000 to around 1500 metres during the course of the day. The wind will remain weak. At 2000 metres the temperature will be around -2 degrees Celsius, at 3000 metres around -6 degrees Celsius. For Sunday, there will be sunshine with veil clouds until midday. In the afternoon, increasingly dense clouds will gather. With light winds, the temperature at 2000 metres will be around 2 degrees, at 3000 metres around -4 degrees Celsius.

The old snow problem remains, the drift snow problem decreases as the snow cover settles.
