Allgäu Alps Central

In particular at high altitudes older snowdrifts still prone to triggering.

The avalanche danger is moderate above 2000m; below it is low. Main problem: the snowdrifts of the last few days. Small to medium-sized slab avalanches can in particular be triggered by large additional loading. Avalanche prone locations are found in particular at high altitudes on steep W/N/E-facing slopes adjacent to ridgelines and in wind-loaded gullies and bowls. In addition, on steep grass-covered slopes isolated small to medium-sized glide snow avalanches can trigger naturally and in steep rocky terrain small loose snow avalanches can trigger naturally.

Embedded in the snowdrifts of the last few days which are partly blanketed, there are in places still trigger-sensitive boundary layers consisting of expansively metamorphosed snow crystals that formed while precipitation paused and surface hoar. In particular on south-facing slopes the layers are increasingly bonding. Easterly wind accumulated spatially very limited snowdrifts. The old snowpack is wind-impacted, encrusted, and the lower part is very compact. Up to intermediate altitudes the snowpack is often moist where bordering the ground which promotes gliding of the snow masses.

Calm high pressure weather is forecast; the avalanche danger will decrease further.
