High-altitude snowdrift accumulations often trigger-prone

High-altitude snowdrift accumulations often trigger-prone

Avalanche danger is moderate above 2000 m, below that altitude danger is low. Main problem: snowdrift accumulations. Isolated danger zones occur in steep ridgeline terrain on N/E/S facing slopes and in wind-loaded gullies and bowls. Small slabs can be triggered by 1 person. The danger of falling generally outweighs that of being buried in snow. In addition, in extremely steep terrain at intermediate altitudes, wet loose-snow avalanches can trigger naturally wherever there is sufficient snow on the ground, mostly small releases.

At high altitudes, snowdrift accumulations will be generated anew by intensifying westerly winds, these can be trigger-prone in ridgeline terrain, especially if weak layers lie embedded inside the snowpack. Otherwise the old snowpack is compact and stable, at intermediate altitudes often thoroughly wet. Due to solar radiation the fresh snow loses its firmness in steep rocky terrain and can begin to glide away. Below 1300 m there is hardly any snow on the ground.

Due to rising temperatures, the wet-snow problem will come to the forefront in the next few days.
