Valsavaranche

Fresh wind slabs are to be evaluated with care and prudence. Moist and wet avalanches at intermediate altitudes.

Fresh wind slabs are to be evaluated with care and prudence. Moist and wet avalanches at intermediate altitudes.

In particular in starting zones where no previous releases have taken place and on wind-loaded slopes medium-sized and, in isolated cases, large natural avalanches are possible as a consequence of warming during the day and solar radiation. Avalanches can in isolated cases be released in deep layers on very steep slopes. Already in the early morning, wet and gliding avalanches are possible. The current avalanche situation calls for caution. Mostly avalanches are shallow and can be released by a single winter sport participant. Backcountry tours and ascents to alpine cabins should be concluded early.

Over a wide area 40 to 70 cm of snow fell in the last few days above approximately 2400 m. As a consequence of new snow and a strong wind, sometimes deep wind slabs formed in particular adjacent to ridgelines and in gullies and bowls as well as at high altitude. The snowpack will be generally moist. It is unfavourably layered. This applies in particular on steep slopes in particular between approximately 2300 and 2700 m in all aspects. In the last two days at intermediate altitudes several small and medium-sized avalanches were reported. At low and intermediate altitudes from a snow sport perspective, insufficient snow is lying.

The danger of moist avalanches will increase during the day.
