Problemi valanghivi
Weather Forecast
Splendid winter weather will prevail in the mountains, hardly any clouds, only light winds. At high altitudes, very mild: at 2000m -1 to +4 degrees; at 3000m -3 to 0 degrees. The nocturnal hours will enjoy clear, star-studded skies, only light winds. Some high fog could form in isolated spots.
Tendency
The proneness to triggering of snowdrift accumulations will gradually diminish.
Snowpack Structure
The fresh fallen snow has been heftily transported. Exposed ridges and crests are windblown, gullies and bowls near the treeline are often filled. Inside the fresh and older drifts there are weak near-surface layers. The snowpack layering above the treeline is inadequiate, several weak layers are evident with faceted crystals.
Avalanche Activity
Moderate snowdrift problem above the treeline
Avalanche danger levels above the treeline are moderate, below that altitude danger is low. Snowdrifts of medium size can be triggered even by minimum additional loading above the treeline, near gulliees and bowls in all aspects. Avalanches will mostly be small sized. Snowdrifts can be difficult to recognize due to poor visibility.
