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. Wet avalanches can in isolated cases be released in near-ground layers. The fresh and somewhat older wind slabs are lying on the unfavourable surface of an old snowpack in particular on shady slopes above approximately 2200 m. They are to be avoided as far as possible. Avalanches can be triggered in the various wind slab layers and reach medium size. Caution is to be exercised in the vicinity of peaks, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. The number and size of avalanche prone locations will increase with altitude. 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. Above the tree line snow depths vary greatly, depending on the infuence of the wind. The fresh wind slabs are in some cases prone to triggering. 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.

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.
