In sintesi

The wind slab can be triggered even with a small additional load

Problemi valanghivi

  • Wind slab

    • Above treeline
  • Gliding snow

    • Below 1,500 m

Tendency

Between 10 and 30 cm of new fallen snow by Tuesday. The risk of slipping snow increases.

Avalanche Activity

The wind slab can be triggered even with a small additional load

The avalanche risk is moderate. Above the tree line, the last wind slab can be triggered as a snow slab in some places even with little additional load. Avalanches can reach medium size. There are avalanche prone locations both adjacent to ridgelines and distant from ridgelines, as well as in steep gullies and in forest aisles. The wind slab is partly covered with snow away from areas adjacent to the ridgeline, crest or summit and the avalanche prone locations are not recognisable everywhere. Spontaneous small gliding avalanches are possible on very steep grassy slopes.

Snowpack Structure

The abundant new fallen snow that fell in the middle of the week under the influence of strong winds from the west to north has settled significantly. On the sunny slopes, it has already been slightly moistened again and covered with a thin crust. Protected from the wind, there is 5 to 10 cm of soft new fallen snow on this base. On the sunny slopes, the snow often lies on previously apery soils up to medium altitudes, on shady slopes on an old snowpack weakened by angular forms (partly also on crusts) and by deep frost. Fractures are mainly possible within the fresh drift snow layers, but in shady high altitudes sometimes also in the persistent weak layer. On very steep sunny slopes, the snow occasionally glides along the ground.

Weather Forecast

The last snow showers will subside during the night, but it will remain cloudy. On Monday, the light will be diffuse due to clouds above summit level, but visibility will initially be sufficient. From midday onwards, higher elevations will be covered in fog and snow showers will pass through as the west/north-westerly wind picks up. In exposed areas, the wind will reach speeds of around 60 km/h. At 1500 m -3 degrees, at 2500 m around -10 degrees.
