Hochschwab Mountains

Moderate avalanche due to fresh snowdrift accumulations. Increasing naturally triggered avalanches as day unfolds.

Moderate avalanche due to fresh snowdrift accumulations. Increasing naturally triggered avalanches as day unfolds.

Avalanche danger above the treeline is moderate, below that altitude danger is low. As winds shift to southerly, frsh snowdrift accumulations will be generated on north-facing slopes. Danger zones increase with ascending altitude, occur behind discontinuities and in gullies and bowls, also distant from ridges, slabs can be triggered by 1 person and can be medium-sized. On sunny slopes, isolated small-to-medium naturally triggered loose-snow avalanches possible in steep rocky terrain. Danger of glide-snow avalanches rising in steep sunny grass-covered terrain at all altitudes. Avoid zones below glide cracks.

The fresh fallen snow from the last 2 days (10-40 cm) is being deposited by southerly winds on leeward slopes as fresh snowdrift accumulations. Weak layers exist (loose layers & faceted forms) in transitions to the snow base and drifts. Isolated more deeply embedded weak layers near crusts are evident on shady slopes in isolated cases.Due to radiation (also diffuse) and warmth the snowpack rapidly becomes moist and forfeits its firmness. Increasing moistness down to the ground leads to gliding activity of the entire snowpack.

Monday night only scattered clouds, a southerly airstream. On Tuesday, thin high-altitude clouds, sunshine often diffuse. As of mid-afternoon, cloud cover will increase from the south, but it will remain dry. Southerly winds intensifying (brisk-to-stormy). Aat 2000 m: 0 degrees; at 1500 m: +3 degrees, somewhat higher in northern regions due to foehn impacdt.

On Wednesday, often overcast, strong-to-stormy southerly winds. Mild. Avalanche danger levels are not expected to change significantly.
