Avalanche Activity

Fresh and snow-covered wind slabs are prone to triggering

The avalanche risk is moderate above the tree line and low below. In north-west to north to south-facing slopes, avalanches can be triggered by individuals in some places. Above 2000 metres, slab avalanches are also possible in persistent weak layers in a few places. Occasionally, avalanches can reach medium size. Danger areas are located at the transition from little to more snow and generally next to blown-off areas as well as in the entrance areas to gullies and bowls filled with wind slabs. Caution in the area of terrain traps.

Snowpack Structure

During the daytime changes, up to 15 cm of new fallen snow will fall, which will be transported extensively. Fresh, prone to triggering snowdrift accumulations form, older snowdrift accumulations are covered with snow. On shady slopes protected from the wind above around 2000 metres, surface hoar has also been covered with snow in places. At high altitudes, especially in northern and eastern aspects, bonded snow overlays a weak old snowpack of faceted crystals and deep frost.

Weather Forecast

The night starts off slightly cloudy. However, the clouds of a warm front soon gather and it starts to snow after midnight. There is a strong southerly wind blowing at up to 80 km/h. On Monday, visibility will be repeatedly restricted by clouds, fog and snowfall. The snowfall level will be around 1000 metres. The sun will stay out longest around midday. In the morning the wind will still be blowing strongly from the south, during the day it will remain strong and turn to the west. A total of 10 to 15 cm of new fallen snow, most of it in the northern Alps. Around -5 degrees at 2000 metres.

Tendency

As the snowfall continues, snowdrift accumulations grow.
