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 can also be triggered in fresh drift snow at a few danger spots, especially near the crest. Below 2800 m, mainly small sliding snow avalanches can be triggered spontaneously.

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.

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 fall in the northern Alps, but the precipitation will be light in the Tauern region. In the afternoon, the sun will shine in the Tauern region, but there will still be a lot of residual clouds in the northern Alps. The wind will be mostly light. At 2000 m -4 to 0 degrees, at 3000 m around -8 degrees.

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