Avalanche Activity

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 south and southwest facing slopes at high altitude, as well as on shady slopes below approximately 2200 m. 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 all aspects at elevated altitudes. 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. Backcountry touring calls for meticulous route selection.

Snowpack Structure

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. 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. This applies in particular on shady slopes at high altitude. The old snowpack consists of faceted crystals. Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes above approximately 2200 m. On sunny slopes below approximately 2200 m only a little snow is now lying.

Tendency

As a consequence of warming during the day and solar radiation more wet and gliding avalanches are possible, but they will be mostly small. As a consequence of highly fluctuating temperatures the snow drift accumulations will stabilise during the next few days.
