Avalanche danger above 1400 m is moderate, below that altitude danger is low. Main problem: wet snow. In extremely steep terrain, wet loose snow avalanches can release spontaneously or can be triggered by one sole person engaged in winter sports in steep terrain. Isolated avalanche prone locations are also found in steep forest aisles with plenty of snow at lower altitudes. In addition, isolated medium-sized glide-snow avalanches can trigger naturally on smooth grass-covered slopes. Avalanches tend to be small. In shady summit and ridgeline terrain, avalanches can in isolated cases fracture down to more deeply embedded layers and can be up to medium-sized.
At summit elevations the snowpack surface will become wet due to rainfall and forfeits its firmness. In shady terrain at highest altitudes there are locally weak layers embedded in the old snowpack consisting of graupel or faceted (expansively metamorphosed) crystals. In isolated cases such weak layers are still prone to triggering. The snowpack base is moist down to the ground, thus enabling gliding movements.
Variable weather. Temperatures are dropping. Danger of wet snow avalanche activity decreases.
