Western Nonsberg Alps

A mostly favourable avalanche situation will prevail. Small avalanches and moist snow slides are still possible in particular in the second half of the day.

A mostly favourable avalanche situation will prevail. Small avalanches and moist snow slides are still possible in particular in the second half of the day.

As a consequence of warming there will be a gradual increase in the danger of wet and gliding avalanches, in particular on west, north and east facing slopes. Avalanches can in very isolated cases be released in near-ground layers, mostly by large additional loads, especially on very steep shady slopes above approximately 2200 m, as well as in gullies and bowls at elevated altitudes. In particular transitions from a shallow to a deep snowpack are unfavourable.

Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes above approximately 2200 m. Above the tree line snow depths vary greatly, depending on the infuence of the wind. The old snowpack consists of faceted crystals; its surface is loosely bonded and consists of surface hoar and faceted crystals. This applies in particular on shady slopes at high altitude. As a consequence of highly fluctuating temperatures a crust formed on the surface. Today the weather will be very warm. These weather conditions will bring about a rapid weakening of the snowpack from the early morning in all aspects. On sunny slopes below approximately 2200 m only a little snow is now lying.

On Saturday it will be very warm. As a consequence of warming during the day and solar radiation more wet and gliding avalanches are possible, but they will be mostly small.
