Avalanche danger is low in the morning, then rises to moderate during the daytime. Main problem: wet snow. Moist and wet loose-snow and glide-snow avalanches can trigger naturally due to solar radiation on steep rocky slopes and on steep, smooth grass-covered slopes. During the course of the day, frequency of avalanches will increase. They can grow to medium size. In addition, on extremely steep high altitude slopes, one sole skier can trigger a slab or loose-snow avalanche. The frequency of avalanche prone locations is low, however, and the risks of taking a fall outweigh those of being buried in snow.
The fresh snow of the last few days has already settled well. Due to solar radiation and wind impact it is bonded like a slab. Bonding to the old snowpack is generally adequate. Following a cold night of clear skies the snow will quickly become moist from solar radiation and forfeit its uppermost firmness. In addition, the snow is becoming wet from the warm earth, it could begin to glide as a single mass.
In case of warm temperatures and precipitation, the wet-snow problem will persist over the next few days. At high altitudes the snowdrift accumulations are a risk.
