Middle Lys Valley

The weather conditions gave rise to rapid and thorough wetting of the snowpack over a wide area.

The weather conditions gave rise to rapid and thorough wetting of the snowpack over a wide area.

The snowpack will become prone to triggering also on shady slopes. In particular in starting zones where no previous releases have taken place small and medium-sized moist and wet avalanches are to be expected. Occasionally large natural avalanches are possible in isolated cases, caution is to be exercised in particular on very steep north, northeast and northwest facing slopes below approximately 2800 m, and on very steep sunny slopes. The new snow and wind slabs are in some cases prone to triggering in all aspects above approximately 2800 m. In addition as the day progresses especially at high altitudes and in high Alpine regions, some mostly small dry avalanches are possible. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.

Over a wide area a mostly overcast night: The surface of the snowpack will only just freeze and will already be soft in the early morning. Above approximately 2900 m snow fell on Sunday in some localities. In some regions rain to the high Alpine regions: These weather conditions gave rise to moistening of the snowpack also at high altitude. Below approximately 2200 m a little snow is lying.

Temporary decrease in danger of moist avalanches as the temperature drops.
