Southern Adamello

A mostly favourable avalanche situation will prevail. Wet and gliding avalanches as the day progresses.

A mostly favourable avalanche situation will prevail. Wet and gliding avalanches as the day progresses.

Avalanches can in very isolated cases be released in the weakly bonded old snow, 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. 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. Wet avalanches can in isolated cases be released in near-ground layers. Backcountry touring calls for meticulous route selection.

Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes above approximately 2200 m. The snowpack will be generally subject to considerable local variations. 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 above the tree line. As a consequence of highly fluctuating temperatures a crust formed on the surface. From early morning the weather will be very warm. These weather conditions will bring about a weakening of the snowpack as the day progresses in all aspects. At intermediate altitudes the snowpack will soften in the morning already. On sunny slopes below approximately 2200 m only a little snow is now lying.

Further warming to the high Alpine regions. On Friday it will be exceptionally warm. The wind will be moderate over a wide area. As a consequence of warming during the day and solar radiation wet and gliding avalanches are possible, but they will be mostly small.
