In sintesi
Cold, fresh snowdrifts
Problemi valanghivi
Snowpack Structure
The fresh snow and fresh drifts blanket surface hoar. The old snowpack at high altitudes is often faceted, further weakened by intermediate melt-freeze layers. Below the treeline the snowfall will often fall on top of an expansively metamorphosed snowpack.
Weather Synopsis
Storm winds and cold in the Northern Alps and along the northern Niedere Tauern, with poor visibility and snowfall. Between 10 and 20 cm of fresh snow is anticipated. Caution: winds intensifying more every hour. From Niedere Tauern to Mürzsteger Alps, gale winds reaching more than 130 km/hr. Temperature at 2000 m: -6 degrees.
Tendency
No significant change in avalanche danger levels is expected.
Avalanche Activity
Cold, fresh snowdrifts
Avalanche danger in the Northern Alps, Niedere Tauern and Hochschwab region is moderate above the treeline. Cold fresh snow and storm winds are making danger zones more frequent above the treeline. Caution in N/E/S aspects: slab avalanches can be triggered even by minimum additional loading, and fracture down to older weak layers.
