Avalanche Activity

Outgoing nocturnal radiation lacking, mild temperatures, rain: wet-snow avalanches. Heed small drifts.

Moderate avalanche danger prevails. Due to rainfall and higher temperatures the snowpack is forfeiting its firmness. As a result, small-to-medium wet-snow avalanches can trigger naturally on very steep slopes in all aspects. On steep grassy slopes, increasingly frequent small-to-medium glide-snow avalanches are possible. At high altitudes, the fresh fallen snow and freshly generated snowdrifts are prone to triggering in places. Such danger zones occur in steep ridgeline terrain and in wind-loaded gullies and bowls. One sole person can trigger small-to-medium sized avalanches.

Snowpack Structure

Due to warmth on Tuesday night and rainfall up to high altitudes, the snowpack is weakened. Inside the drifts are weak layers, e.g. graupel. Fresh snow and drifts lie deposited atop a thoroughly wet and thereby weakened snowpack surface (with graupel). At low altitudes the fresh snow of recent days fell on bare ground.

Weather Synopsis

Nocturnal hours: heavily overcast skies, rainfall in the latter part of the night up to over 2000 m. Thursday: instable and windy conditions, predominantly overcast skies, rain shower up to over 2000 m. In the afternoon the snowfall level will descend to below 2000 m. At 2000 m: +6 to +2 degrees. Brisk to strong westerly winds.

Tendency

Friday will bring snowfall above 1600 m, accompanied by strong W/SW winds. On Saturday, snowfall down to 1000 m. Avalanche danger could increase at high altitudes. Danger of wet-snow avalanches will recede as temperatures drop.
