Avalanche Activity

New fallen snow with wind

Snowfall in the mountains ranged from 5 to 10 cm, and locally in the Kamnik-Savinja Alps a little more. It will snow again on Wednesday morning and into the morning. Snowfall is expected to range from 5 cm to 1 cm. Slightly more - up to 20 cm in the Savinja Alps and eastern Karavanke. At the same time, north to north-easterly winds are picking up, bringing fresh snow and building up new snow layers in the south and west. The new fallen snow is less able to adhere to the older snow base. The danger is higher especially on slopes and in gullies where the height of the New fallen snow is greater due to the snow layering.

In addition to new fallen snow, weak layers in the snowpack deeper in the snowpack are a problem. These weak layers are more numerous 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

As the weather cooled, the older snow base froze. Dry and light snow has fallen on harder ground and is now carried by the wind. During the snowfall, the local fall of Graupel may also have provided a new weak layer.

In the old snow cover, the layers of snow are mostly well connected, with a Crust on top, which mostly supports the skier's weight. Deep below the surface, several weak layers of faceted snow crystals and sheared grains occur.

Weather Forecast

Wednesday will be quite cloudy, with light to moderate snow at first. In the afternoon, clouds will break in places and light snow will mostly taper off. A total of 5 to 10 cm of dry snow may still fall. Slightly more in the Savinja Alps and eastern Karavanke. There will be moderate winds from the north to north-east, which may be strong in exposed areas, carrying fresh snow. Temperatures will be around -2 °C at 1500 m and -8 °C at 2500 m.

Tendency

Thursday will be clear at first, with variable cloud formation during the day. Some peaks will be occasionally cloudy. Winds will weaken slightly. Avalanche danger will remain similar.
