Lower Tauern South

Isolated medium-sized wet-snow and glide-snow avalanches

Isolated medium-sized wet-snow and glide-snow avalanches

Avalanche danger is initially low, then rises to moderate. In a few places on steep slopes below 2800m, small-to-medium moist/wet avalanches can trigger naturally, or be triggered by winter sports enthusiasts. In isolated cases, small-to-medium glide-snow avalanches are possible. In the Hohe Tauern above 2800m in wind loaded shady terrain, in shady gullies and bowls, dry-snow slab avalanches can be triggered by minimum additional loading. In isolated cases avalanches can fracture down to deeper layers and then grow to medium size.

The compact snowpack is moist/wet up to high altitudes even in early morning, i.e. wet weak layers in the old snow are only evident in isolated cases above 2600m. In high-alpine zones, a melt-freeze crdust of settled often wind-impacted snow forms. Due to solar radiation and regional rainfall up to high altitudes, the snowpack is forfeiting its firmness.

Monday night skies will be densely cloudy, final showers will taper off in the early part of the night. On Tuesday, residual clouds and high-altitude cirrus clouds, but intermittent sunshine. Dry skies in the morning, frequent showers later on south of the Tennengebirge, isolated thunderstorms. Snowfall level at 2700m. Winds light to moderate from the north, also from the south on the Main Alpine Ridge. At 2000m: +3 degrees in the north, +7 degreres in the south; at 3000m: -2 degrees.

On Wednesday, more marked daytime danger cycle of naturally triggered avalanches due to previously improved nocturnal outgoing radiation.
