The new snow of the last two days represents the main danger. This snow can be released easily or naturally in all aspects above the tree line. The new snow can be released by a single winter sport participant especially on west to north to south facing aspects above the tree line. Over a wide area 50 cm of snow, and up to 70 cm in some localities, will fall until the early morning above approximately 1800 m. In particular in the regions exposed to heavier precipitation numerous medium-sized and, in isolated cases, large slab avalanches are to be expected as the snowfall becomes more intense. As a consequence of new snow and a sometimes storm force wind, sometimes large wind slabs will form in the course of the day in all aspects. The off-piste conditions are dangerous. Temporary safety measures may be necessary.

dp.6: cold, loose snow and wind
Over a wide area 50 cm of snow, and up to 70 cm in some localities, will fall until the early morning above approximately 1800 m. The new snow can be released easily or naturally in all aspects above the tree line. Snow profiles and stability tests have confirmed the distinct danger. The covering of new snow is soft. Distinct weak layers in the upper part of the snowpack are difficult to recognise. The new snow will be deposited on surface hoar in areas close to the tree line. Above the tree line: Towards its base, the snowpack is faceted and weak. Over a wide area new snow is lying on a weakly bonded old snowpack. Avalanches can be released in deeper layers very easily.

The danger of wet and gliding avalanches will increase during the day, reaching danger level 4 (high). As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase significantly in particular on steep slopes below the tree line. The surface of the snowpack is hardly frozen at all and will already soften in the late morning. A clear night will be followed in the early morning by quite favourable conditions generally, but the danger of wet and gliding avalanches will increase later. During the morning as well, individual, then as the precipitation becomes heavier more wet avalanches are to be expected. On steep southeast, south and southwest facing slopes and at low and intermediate altitudes numerous medium-sized to large natural wet avalanches are to be expected as a consequence of warming. On sunny slopes a high danger of wet and gliding avalanches will be encountered over a wide area. As the temperature drops there will be a gradual decrease in the avalanche danger towards the evening.
