Werdenfels Alps

Weak layers become reactive with moisture penetration.

Weak layers become reactive with moisture penetration.

The avalanche risk above 1800 m increases from moderate to considerable during the daytime changes. Below that, it is low in the morning and moderate later on. With sunshine, wet snow in combination with persistent weak layers becomes a problem. Particularly in extremely steep terrain, wet loose snow and slab avalanches release by themselves or with little additional load. Wet soft and slab avalanches reach medium size.

On steep slopes with smooth ground that have not yet been discharged, wet, medium-sized gliding avalanches can also occur at any time in all aspects.

The snow surface usually freezes through overnight and softens again with the sunlight. At high altitudes, there are potential weak layers, especially on shady slopes, in the area of crusts in the upper metres of the snowpack. In mild temperatures, the snowpack at higher altitudes in the northern aspects also becomes increasingly moist from above. The snowpack base is still dry at high altitudes and often consists of faceted crystals, while at medium altitudes it is usually wet. On the south side, the ground pales again at low altitudes.

The avalanche danger is decreasing slightly.
