Middle Lys Valley

The danger of moist and wet avalanches will increase quickly during the day.

The danger of moist and wet avalanches will increase quickly during the day.

The surface of the snowpack will freeze to form a strong crust and will soften quickly. In steep terrain there is a danger of falling on the hard snow surface. As a consequence of warming, the activity of moist and wet avalanches will increase. This applies especially on very steep sunny slopes at intermediate and high altitudes, and in steep rocky terrain. Also below approximately 2700 m and on very steep shady slopes individual medium-sized natural wet avalanches are possible as a consequence of warming during the day and solar radiation.

The spring-like weather conditions gave rise to rapid settling of the snowpack. This situation gave rise to increasing moistening of the snowpack below approximately 2700 m. The amount of snow is subject to significant local variations. Especially on sunny slopes below the tree line no snow is lying. On shady slopes below the tree line hardly any snow is lying. Especially on the colder slopes above the treeline, in the valley basins and headlands that have been less affected by stormy winds in recent weeks, there is excellent snow cover. Weak layers exist in the bottom section of the snowpack in particular at high altitudes and in high Alpine regions.

As a consequence of warming during the day small and, in isolated cases, medium-sized moist and wet avalanches are possible below approximately 3300 m.
