Avalanche Activity

New fallen snow has not adhered well to the old snow base

New fallen snow has put additional load on the weak layers in the old snow cover. Places with blown snow and shady areas where there is a weak layer deep in the snowpack are more dangerous. In particular, at low loads, medium-sized avalanches of packed snow will be possible. A major Avalanche cannot be ruled out. Below 1700 m, gliding avalanches will be possible, especially on steep grassy slopes.

Snowpack Structure

It snowed on Wednesday and Thursday, with moderate to strong southerly winds at first, which built up in large areas. In total, 20 to 50 cm of snow fell. In the central mountains, snow fell first quite wet and then increasingly dry. Deep and persistent weak layers are present in the old snow cover. The snowpack is unstable in many places. Crust has formed in some places on sunny slopes.

Weather Forecast

On Sunday, it will be quite clear in the high alpine regions, but mostly cloudy and foggy at lower altitudes. Clarity will be more frequent in the western Julian Mountains. There will be light to moderate easterly winds. Temperatures will be around -5 °C at 1500 m and -8 °C at 2500 m.

Tendency

It will clear in the high alpine regions, while clouds will remain at lower altitudes. It will be cooler. The danger of Avalanches will remain similar.
