Fresh and older wind slabs are prone to triggering.
The avalanche danger is moderate above 2000 metres and low below that. In some places, wind slab avalanches can be triggered as small to medium sized slab avalanches at high altitudes due to low additional loads. This occurs adjacent to the ridgeline and distant from ridgelines in steep terrain in northern and eastern aspects as well as in gullies and bowls. In addition to the risk of burial, the risk of being swept away and falling must be taken into account.
Snowpack
Fresh and older snowdrift accumulations lie on unfavourable layers, especially on the shady slopes, sometimes prone to triggering. At higher and higher altitudes, faceted crystals are often found below a melt-freeze crust close to the surface. Snow depths are below average at all altitudes.

Slow decline in avalanche danger.

Avalanches can be of medium size.
The avalanche risk is moderate above the tree line and low below. Wind slab avalanches can be triggered by even a small additional load. This occurs adjacent to the ridgeline and distant from ridgelines in steep terrain in northern and eastern aspects as well as in gullies and bowls. Avalanches can reach medium size. In addition to the risk of burial, the risk of being swept away and falling must be taken into account.
Snowpack
With a focus on the Allgäu, 10-25 centimetres of new fallen snow will fall, carried by stormy winds from westerly directions. The fresh and older snowdrift accumulations often lie unfavourably on a thin melt-freeze crust, especially on the shady slopes. Under the melt-freeze crust, the snow has built up and forms a weak layer. Intermediate layers prone to triggering can also be contained within the wind slab. The snow depths are below average at all altitudes.

Watch out for small snowdrift accumulations.
The avalanche risk is low. Occasionally, small snowdrift accumulations can be triggered as a small slab by a small additional load. This occurs adjacent to the ridgeline and distant from ridgelines in the steep terrain of northern and eastern aspects. Be aware of the risk of being swept away and falling.
Snowpack
Stormy winds and a few centimetres of new fallen snow have created small-scale wind slabs. The fresh and older snowdrift accumulations are only slightly thick, but are prone to triggering, especially on the shady slopes. At higher and higher altitudes, there are often faceted crystals down to the ground below a melt-freeze crust close to the surface. There are only a few centimetres of snow on the sunny slopes.
