Persistent weak layer remains the main danger

Persistent weak layer remains the main danger

The avalanche risk is moderate above the tree line and low below. On shady slopes, medium dry slab avalanches can be triggered by individuals in a few places. Most likely at the transition from little to more snow. Danger areas are difficult to recognise, which is why defensive route selection is still advised. Individual gliding avalanches occur on steep grassy terrain. Wet loose snow avalanches and snow slabs from sunny slopes that have not yet been unloaded are also possible.

On the sunny slopes, the snowpack has a (more or less stable) melt-freeze crust for a short time, underneath it is moist to wet up to high altitudes. On the shady slopes, soft, dry snow can still be found from around 1800 metres. The new and wind slab snow of the last week has settled and is often well connected to each other. However, the connection to the angular persistent weak layer below is still poor in places. Deep and sunny mid-levels are often already snowed out.

Extensive clouds in medium-high layers will pass through during the night. On Monday, denser clouds and patches of high fog may initially restrict visibility more often. From midday, the sun will often shine alongside soft spring clouds. The wind will be mostly light from east to south. Temperatures at 2000 metres around 0 degrees.

The persistent weak layer problem is only slowly weakening. Slight daytime changes in wet avalanches on Wednesday.
