Avalanche Activity

Daytime increase in avalanche danger due to fresh snow and wind

Avalanche danger during the morning will be moderate above 2200m, below that altitude danger is low. With increasing amounts of fresh fallen snow, avalanche danger above 2200m will rise to CONSIDERABLE. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size. Danger zones occur in the old snow on north-facing slopes above 2200m, in all aspects above 2400m. Fresh snowdrift accumulations occur both near to and distant from ridgelines, behind protruberances in the terrain, and in gullies and bowls. Particularly below 2000m the old snowpack is thoroughly wet and small-to-medium wet-snow avalanches are possible. Avalanches in high altitudes can sweep along more deeply embedded layers of the snowpack and in isolated cases plummet all the way down to the green zones. Small-to-medium glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.

Snowpack Structure

By Saturday evening 30cm of fresh snow is anticipated at high altitudes. Above 2200m on north-facing slopes weak layers of faceted crystals are found in the lowermost part of the snowpack. Above 2400m on W/S/E facing slopes there are faceted crystals between crusts. Inside the snowdrifts, in addition, trigger-sensitive layers can form rapidly. Below 2000m the snowpack will forfeit its firmness on Friday night due to rainfall and water seepage.

Weather Forecast

The mountains will be shrouded in dense clouds all day long, rainfall and snowfall will be persistent and moderate, the snowfall level at 1600m, on Friday evening still at 2000m in places. At high altitudes in the Tauern, strong N/NW winds, intensifying during the daytime hours, reaching windspeeds of 60 km/hr. Elsewhere winds will be moderate to brisk. At 2000m: -3 degrees, at 3000m: -7 degrees C.

Tendency

On Saturday night, increase in avalanche danger due to fresh snow and wind
