Old wind slabs require caution. Moist snow slides and gliding avalanches are to be expected from the middle of the day.

Old wind slabs require caution. Moist snow slides and gliding avalanches are to be expected from the middle of the day.

The old wind slabs can still be released in some cases in all aspects and generally at elevated altitudes. Sometimes the avalanches in these loacations are medium-sized. The avalanche prone locations are to be found especially in gullies and bowls, and behind abrupt changes in the terrain and adjacent to ridgelines. Weak layers deep in the old snowpack can still be released in very isolated cases on little-used, rather lightly snow-covered shady slopes. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example in extremely steep terrain. Also extremely steep shady slopes: An appreciable danger of dry snow slides exists. As a consequence of warming during the day and solar radiation small and, in isolated cases, medium-sized moist loose snow avalanches are to be expected in all altitude zones. The avalanche prone locations are to be found in particular on very steep sunny slopes. On very steep grassy slopes more gliding avalanches are possible at any time, even medium-sized ones. Backcountry touring and other off-piste activities call for meticulous route selection.

The wind slabs of recent weeks are poorly bonded with the old snowpack in particular on rather lightly snow-covered shady slopes and generally at elevated altitudes. Whumpfing sounds and snow profiles indicate the unfavourable bonding of the snowpack in particular in shady places that are protected from the wind. Above the tree line there are 50 to 100 cm of snow, and even more in some localities. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind.

Friday: The danger of dry avalanches will decrease gradually. On Friday it will be very warm. The danger of moist avalanches will already increase in the early morning.
