Valgrisenche

The avalanche prone locations 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. 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.

50 to 80 cm of snow, and even more in some localities, has fallen since Tuesday above approximately 2000 m. Here rain fell up to 2100 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.

Dry and moist avalanches are possible in some places.
