Wet-snow avalanches during the course of the day

Wet-snow avalanches during the course of the day

Due to daytime warming and solar radiation, wet loose-snow avalanches can be expected particularly on south- and west-facing slopes. Isolated wet-snow avalanches can grow to large size, whenever they fracture down to deeper levels of the snowpack. On steep grass-covered slopes, glide-snow avalanches can occur. Zones with glide cracks on the surface should under all circumstances be avoided. Particularly on very steep shady slopes above 1800m, avalanches can fracture down to deeper-down layers inside the snowpack, especially where the snowpack is not capable of bearing loads.

During nights of clear skies, a melt-freeze crust capable of bearing loads frequently forms on the snowpack surface. Due to solar radiation, it rapidly softens up during the day. The snowpack is moist-to-wet over far-reaching areas. Above 1800m on shady slopes, there are still weak layers in the lowermost part of the snowpack fundament.

Some sunshine, slight foehn conditions. Initially the skies will be cloudless, during the course of the day some cirrus clouds will move in, later on cloud cover at intermediate altitudes will pass through, but not hampering the generally sunny character of the day. Starting in afternoon it will slowly become colder. Temperature at 2000m: +5 degrees; at 3000m: -2 degrees. Moderate southwesterly winds at high altitudes.

As the result of a weak cold front on Sunday, minor snowfall above 1300-1500m is anticipated. As temperatures drop, the gliding snow and wet-snow avalanche activity will decrease.
