Middle Lys Valley

The snowpack will be in most cases stable. In some localities increase in danger of moist and wet avalanches as the penetration by moisture increases.

The snowpack will be in most cases stable. In some localities increase in danger of moist and wet avalanches as the penetration by moisture increases.

A mostly favourable avalanche situation will prevail. In the morning there is a risk of slipping on hard snow. It is advisable to bring a snow knife and crampon with you for the steeper sections. The surface of the snowpack will soften during the day. Until the temperature drops individual gliding avalanches and wet snow slides are possible, but they will be mostly small, in particular in case of releases originating from very steep sunny starting zones below approximately 2600 m that still retain some snow. Areas with glide cracks are to be avoided as far as possible. Moist and wet avalanches can be released in near-surface layers, in particular by large additional loads. The avalanche prone locations are to be found in particular on extremely steep southeast, south and southwest facing slopes and in places that are protected from the wind. These avalanche prone locations are rather rare. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

The avalanche conditions in the morning, after a clear night, are quite favourable. The surface of the snowpack has frozen to form a strong crust. Low and intermediate altitudes and sunny slopes: The conditions are spring-like. In particular steep south, west and southeast facing slopes: Towards its surface, the snowpack is hard and its surface has a melt-freeze crust that is strong in many cases. The high temperatures as the day progresses will give rise to slight softening of the old snowpack. Below approximately 2200 m only a little snow is lying on south and southwest facing slopes. Above the tree line snow depths vary greatly, depending on the infuence of the wind. Also adjacent to ridgelines hardly any snow is lying.

In some localities some new snow above approximately 2000 m: The avalanche danger will increase but remain within the current danger level.
