Avalanche Activity

Moderate avalanche danger - fresh wind slab and wet snow!

The avalanche risk is predominantly moderate. Due to new fallen snow and strong winds, fresh snowdrift accumulations can form, especially in the high areas adjacent to ridgelines, which must be observed. Locally, wet, naturally triggered avalanches of medium intensity are possible from very steep, extreme terrain below the snowfall level. In the shady high altitudes, slab avalanches can still be triggered in very steep terrain due to the old snow problem.

Snowpack Structure

New fallen snow and wind are causing fresh snowdrift accumulations in the higher elevations. Below the snowfall level, rainfall causes a decreasing firmness of the snowpack. The old snowpack is moist to wet up to high altitudes. However, weak layers may still be present in the old snowpack, which is not yet moist, especially on shady slopes and at higher elevations. The snowpack can also start gliding snow on the ground.

Weather Forecast

On Friday, visibility will often be limited by dense clouds and snow or rain showers. The snowfall level will be around 1800 metres. The north-westerly wind will be brisk to strong, sometimes stormy at exposed high altitudes. At 1500 m around 1 degree, at 2000 m around -1 degree. Increasingly sunny on Saturday. The day will start mostly cloudy. From around midday, the sun will prevail. Light to moderate winds from north to east. Temperatures will rise during the day. At 1500 m to around 6 degrees, at 2000 m to 4 degrees.

Tendency

With the expected rise in temperatures and sunshine on Saturday, there will be daytime changes in the avalanche risk.
