Weakly bonded old snow represents the main danger. Wet avalanches as the day progresses.

Even single persons can release avalanches easily, especially on very steep shady slopes above approximately 2200 m, as well as on very steep east and west facing slopes above approximately 2400 m. The avalanches can be released in the weakly bonded old snow and reach medium size. Caution is to be exercised at transitions from a shallow to a deep snowpack. As the day progresses the likelihood of avalanches being released will increase a little. In addition the somewhat older wind slabs are capable of being triggered in some cases still. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase, in particular on sunny slopes below approximately 2600 m. Backcountry tours should be concluded timely.

Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. The wind slabs are in some cases still prone to triggering at high altitudes and in high Alpine regions. Released avalanches and field observations confirm this situation. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack. These conditions will bring about a gradual weakening of the snowpack.

Sunday: Slight decrease in danger of wet and gliding avalanches as the temperature drops.
