Border Pennine Alps

Individual weak layers exist in the snowpack. The weather conditions will cause a slight weakening of the near-surface layers in the early morning in particular on sunny slopes.

Avalanches can in isolated cases be released in the old snowpack and reach medium size in particular on very steep shady slopes, caution is to be exercised in steep rocky terrain, as well as on steep, little used shady slopes. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls. As a consequence of warming during the day and the solar radiation, the likelihood of dry and moist avalanches being released will increase a little in particular on steep southeast and south facing slopes below approximately 2600 m. Here avalanches are possible in the late morning, but they will be mostly small.

High altitudes and the high Alpine regions: As a consequence of mild temperatures, low relative humidity and the light wind, the snow drift accumulations stabilised during the last few days. In shady places that are protected from the wind: Towards its surface, the snowpack is fairly homogeneous; its surface is loosely bonded and consists of surface hoar and faceted crystals. Very steep sunny slopes: Towards its surface, the snowpack is largely stable and its surface has a melt-freeze crust that is strong in many cases. The high temperatures on Thursday gave rise to significant moistening of the snowpack over a wide area on sunny slopes. Towards its base, the snowpack is faceted. This applies in particular on steep east, north and northwest facing slopes,.
