Danger of slab avalanches down to the treeline, wet loose-snow avalanches below there

Avalanches can be triggered even by one sole winter sports enthusiast. Danger zones occur on very steep slopes in all aspects, behind drops in the terrain and in wind-loaded gullies and bowls, particularly at the upper limits of the timberline. Rainfall and higher temperatures are softening the snowpack at low and intermediate altitudes, which can lead to naturally triggered medium-sized loose-snow avalanches. Zones where there are glide cracks on the surface should be avoided.

All in all, about 20cm of fresh snowfall was registered on Saturday from the warm front, falling as rain at lower altitudes. The snowpack surface at intermediate altitudes is already wet in many places.

Rainfall and snowfall will taper off in the early part of the night. During daytime hours, generally partly to heavily clouded with light snow showers locally and occasional sunshine. Winds will slacken off, temperatures rise. Temperature at 2000m: rising from -2 to +2 degrees, at 3000m at -5 degrees. Moderate westerly winds at high altitudes, in high alpine regions often blowing at brisk strength.

The early part of the week will bring rising temperatures and only minor amounts of precipitation. Particularly at low and intermediate altitudes, wet-snow and glide-snow avalanches can be increasingly expected.
