Middle Lys Valley

The conditions are generally favourable for backcountry touring and other off-piste activities.

The conditions are generally favourable for backcountry touring and other off-piste activities.

Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. They can in some cases reach medium size. This applies in particular on very steep northwest, north and northeast facing slopes above approximately 2300 m in little used backcountry terrain. Such avalanche prone locations are barely recognisable, even to the trained eye. As a consequence of warming during the day and solar radiation small and medium-sized natural wet avalanches are to be expected. They can in some cases release the entire snowpack. This applies especially on steep south, southeast and west facing slopes below approximately 2700 m. The wind slabs of the last few days are in individual cases still prone to triggering above approximately 2700 m.

A clear night will be followed in the early morning by favourable conditions, but the danger of wet avalanches will increase later. As a consequence of mild temperatures and solar radiation the snowpack consolidated during the last few days. Sunshine and high temperatures gave rise to moistening of the snowpack in particular on sunny slopes below approximately 2700 m. As a consequence of highly fluctuating temperatures a crust formed on the surface during the last few days, this also applies on shady slopes below approximately 2200 m. In particular at intermediate altitudes less snow than usual is lying. On sunny slopes below approximately 2100 m hardly any snow is lying.

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of moist and wet avalanches. Gradual decrease in danger of dry avalanches.
