Points saillants

Heed freshly generated snowdrift accumulations

Problèmes avalancheux

  • Wind slab

    • Toutes altitudes
  • Gliding snow

    • Toutes altitudes

Snowpack Structure

Winds were NW/W, transported the cold loose snow and deposited drifts atop unbonded fresh snow. Fracture points are generally found just below the slab in the fresh fallen snow. There are hardly any weak layers. Fresh snow and drifts are bonding only slowly. The fresh snow was often deposited on bare ground. There, on steep grassy slopes, increasing gliding masses can be expected.

Weather Synopsis

Visibility is adequate. It will remain mostly dry. Westerly winds will reach 30-40 km/h. At 2000 m: -4 degrees.

Tendency

The snowpack will gradually settle, avalanche dangers will incrementally recede.

Avalanche Activity

Heed freshly generated snowdrift accumulations

Avalanche danger is CONSIDERABLE above the treeline, below that altitude danger is MODERATE. Fresh snow and freshly generated snowdrifts above the treeline are easily triggered in some places in all aspects, also naturally, esp in gullies, bowls, behind abrupt drops in the terrain. Danger zones are not visible to the naked eye, increase with ascending altitude. Unfavourable conditions for backcountry tours. In addition, on previously bare grassy slopes below 2400 m, the danger of glide-snow avalanches will increase. Isolated small-to-medium sized naturally triggered glide-snow avalanches are possible.
