Middle Lys Valley

The avalanche prone locations are numerous but are difficult to recognise. Ski touring and other off-piste activities, including snowshoe hiking, call for defensive route selection.

As a consequence of wind from westerly directions, further wind slabs will form by Tuesday. Fresh and somewhat older wind slabs can be released by a single winter sport participant in all aspects. This applies in particular on very steep slopes, as well as adjacent to ridgelines and in gullies and bowls. Natural avalanches are further to be expected. The avalanches can be released in the new snow and wind slab layers and reach large size in some cases. In the typical avalanche paths in particular the avalanches can reach a long way. As a consequence of solar radiation more moist and wet avalanches are possible as the day progresses. This applies in particular on very steep sunny slopes.

60 to 100 cm of snow, and even more in some localities, has fallen since Tuesday above approximately 2000 m. Here rain fell up to 2200 m. The sometimes strong wind has transported the new snow significantly. In some places new snow and wind slabs are lying on soft layers. The upper section of the snowpack is unfavourably layered. Numerous medium-sized and large dry and wet avalanches have been released.

As a consequence of warming during the day and the solar radiation, the likelihood of moist and wet avalanches being released will increase gradually.
