Strong increase in avalanche danger already in the morning!
Rapid increase in avalanche danger during the day in some cases
The avalanche danger increases from low to moderate during the day changes. After generally favourable conditions in the morning, the danger of naturally triggered avalanches often increases rapidly as the sun shines and the weather warms up. Medium-sized and occasionally large wet loose snow and slab avalanches can be expected in all aspects, in particular on sunny slopes. Wet avalanches can also be triggered by winter sports enthusiasts. In addition, gliding avalanches can be triggered at any time on steep slopes with smooth ground.
In extremely steep, shady areas above 2000 m, small to medium-sized slab avalanches can still be triggered by individuals (persistent weak layer problem).
Snowpack
With outgoing longwave radiation, the snow surface can consolidate, but softens again with the sun's rays. The hardness of the surface varies depending on the effect of the wind. With increasing moisture penetration, the snowpack loses firmness and stability. In addition to loose snow avalanches, spontaneous, wet slab avalanches can also be expected, as liquid water in the snowpack can reactivate former weak layers in the persistent weak layer. In very steep areas with a wet layer on the ground, the snowpack can slide off.
Only in very shady areas above 2000 m does the snowpack still have cold reserves and, in some cases, persistent weak layers in the old snow that are prone to triggering.
Tendency
Sunny mountain weather again on Thursday until the early afternoon. The avalanche danger will not change significantly.

Avalanche Problem
Wet snow
Low avalanche danger, but watch out for spontaneous wet snow slides!
The avalanche risk is low. Nevertheless, during the daytime changes, the triggering of wet avalanches increases somewhat. Wet avalanches can mainly come from multiple starting zones that are not yet fully discharged. These are usually small but can also be easily triggered by individual winter sports enthusiasts. The risk of being swept away and falling should be taken into account.
Only in extremely steep, shady areas above 2000 m can very occasionally small to medium-sized slab avalanches be triggered (persistent weak layer problem).
Snowpack
With outgoing longwave radiation, the snow surface can consolidate somewhat, but softens again with sunlight. The thin snowpack becomes damp or wet in all areas and loses firmness. Only in very shady areas above 2000 metres does the snowpack still have small cold reserves and occasional weak layers in the persistent weak layer.
In general, there is very little snow and the depletion is progressing.
Tendency
Sunny mountain weather again on Thursday until the early afternoon. The avalanche danger will not change significantly.
