Avalanche Activity

New and blown snow

On Wednesday, precipitation started to fall in the north during the night. The snowfall level was initially at around 1500 m and quickly dropped. The snow weakened temporarily at midday on Thursday. After the passage of a cold front, a strong northerly wind blew, carrying New fallen snow and building up new snow layers on the southern flanks. A total of 15-30 cm of new fallen snow fell in the mountains.

New fallen snow and blown snow are the main dangers. Danger is increased especially on slopes and in gullies where the height of New fallen snow is greater due to snow accumulations. Saturday will be sunnier than the previous days and warmer. On sunny slopes, the snow will dry out during the day and freeze overnight. Minor wet snow avalanches are possible, especially on extreme terrain such as steep slopes or cliffs.

In addition to new fallen snow, weak layers in the snowpack deeper in the snowpack may be a local problem. These weak layers are more common in the axis above the forest. In particular, a large avalanche can be triggered if the load exceeds the load-bearing capacity of these layers.

Snowpack Structure

15-30 cm of dry and light snow fell in the mountains. A strong northerly wind blew in with the snow, blowing the snow down to the old base in many places. During the previous snowfall, there was some local fall of graupel, which is a potentially dangerous weak layer. Locally, the layers of Graupel are 5-10 cm thick, possibly more.

In old snow cover, the snow layers are mostly well connected. Deep below the surface, several weak layers of faceted snow crystals and sheared grains occur, especially on the axial sides.

Weather Forecast

Partly clear, with more clouds in the eastern mountains. Initially there will be a strengthening northerly breeze, which will weaken somewhat during the day. Warmer. Temperatures will be around 0 °C at 1500 m and -4 °C at 2500 m by mid-day.

Tendency

There will be more clouds in the coming days, small showers are possible early next week. The danger of avalanches will remain similar.
