Self-triggering of wet snow avalanches, wind slab problem at altitude.

Self-triggering of wet snow avalanches, wind slab problem at altitude.

The avalanche danger is moderate. The main problem is wet snow. Wet loose snow, gliding snow and slab avalanches can detach themselves in all aspects. Wet avalanches can reach medium size.

Wind slab avalanches are also problematic. Slab avalanches can be triggered at higher altitudes on steep slopes from north-west to east to south aspects and in gullies and bowls with little additional load. Slab avalanches can reach medium size.

The warm temperatures and solar radiation lead to further soaking of the snow cover, causing the snow to lose its binding properties. Up to high altitudes, the snow cover, snowpack is wet or at least moist near the surface. A melt-freeze crust forms on the surface overnight, which thaws again during the daytime changes. At higher altitudes, the base of the snowpack is still dry and angular. Here, older snowdrift accumulations are sometimes still prone to triggering on soft layers or surface hoar in the upper part of the snow cover, snowpack.

Slow decline in avalanche danger.
