Wet-snow danger in very steep terrain where there is still lots of snow

Wet-snow danger in very steep terrain where there is still lots of snow

Snowfall above 2300m accompanied by brisk westerly winds, thus transporting it. Due to daytime warming and rainfall initially up to 2300m, danger of wet-snow avalanches will increase in morning hours. Wet slab avalanches can be triggered by winter sports enthusiasts. Also isolated naturally triggered wet-snow avalanches are possible. Caution urged above all towards steep shady slopes at 2200-2500m which have not yet discharged and generally slopes in aspects where there is still area-wide snow on the ground. Avalanches can fracture in weak old snowpack layers, in isolated cases grow to large size and have atypically long runout zones. Whumpf noises and breaking through the surface crusts of old snow are indicators of danger. On snowy, steep slopes with smooth underground (such as grass-covered slopes and rock plates) which have not yet discharged, glide-snow avalanches can trigger in all aspects.

In evening hours, outgoing radiation will still be effective, but during nighttime hours due to heavy cloud cover, increasingly limited. In early morning hours, rain showers will set in up to 2300m. As showers increase, the snowfall level will drop to about 1800m during the day. The snowpack is thoroughly wet up to summit zones in all aspects. Lower altitudes are bare of snow. Sunny slopes are becoming bare of snow up to high altitudes.

A cold front. Thus, cloudy skies emerging from night, perhaps foggy and showers in early morning. During the daytime, showers will increase, thunderstorms cannot be ruled out. Temperatures will gradually drop, the snowfall level descend from 2300 to nearly 1800m. Bright windows will not persist. Temperature at 2000m: dropping from +4 to +1 degree; at 3000m: from -2 to -5 degrees. Brisk westerly winds at high altitudes.

Wet-snow avalanche activity will recede as temperatures drop
