In sintesi

Weakly bonded old snow requires caution. Loose snow avalanches and gliding avalanches are still possible.

Snowpack Structure

5 to 10 cm of snow will fall on Sunday. The wind will be moderate adjacent to ridgelines. The new snow and wind slabs of Friday are lying on the unfavourable surface of an old snowpack in particular on west to north to east facing aspects above approximately 2400 m. Fresh wind slabs are lying on soft layers on near-ridge shady slopes. Somewhat older wind slabs are covered with new snow and therefore barely recognisable.

Tendency

Weakly bonded old snow represents the main danger. The danger of gliding avalanches will persist.

Avalanche Activity

Weakly bonded old snow requires caution. Loose snow avalanches and gliding avalanches are still possible.

Weak layers in the old snowpack can be released in some places even by individual winter sport participants. The avalanche prone locations are to be found in particular on west, north and east facing slopes above approximately 2400 m. Avalanches can reach large size in isolated cases. Fresh avalanches and whumpfing sounds serve as an alarm indicating the danger. In addition the wind slabs of the last few days are capable of being triggered in some cases. Such avalanche prone locations are to be found in particular on very steep shady slopes above the tree line, caution is to be exercised in particular adjacent to ridgelines and in pass areas. These places are sometimes covered with new snow and are therefore difficult to recognise. As the day progresses more small and medium-sized loose snow avalanches are possible, in the event of solar radiation especially. On steep grassy slopes small and medium-sized gliding avalanches are possible as a consequence of the new snow, especially on sunny slopes below approximately 2400 m. Backcountry touring and other off-piste activities call for careful route selection.
