Considerable avalanche danger widespread in backcountry

Considerable avalanche danger widespread in backcountry

Fresh snow and drifts are prone to triggering. Danger zones occur particularly behind protruberances in the terrain and in wind-loaded steep terrain. Frequency and spread tend to increase with ascending altitude. Avalanches can be triggered even by the weight of one sole skier. If avalanches fracture down to deeper layers of the snowpack they can grow to large size. At low altitudes on steep grassy slopes, increasingly frequent small-to-medium glide-snow avalanches are possible. Due to solar radiatilon, loose-snow avalanches can be expected in rocky terrain.

The large amounts of fresh fallen snow and drifts, particularly at high altitudes, are poorly bonded with the old snowpack, making them prone to triggering. In the upper part of the snow layering there are weak layers evident (blanketed graupel / inside the latest snowdrift layers). At high altitudes on shady slopes there are weak layers inside the old snowpack, down to which avalanches could fracture.

NIghttime skies will be dry, little cloud, very cold. On Wednesday, sunshine from the start, often cloudless skies. Below 1000m, some fogbanks could prove persistent in the morning. During the daytime, temperatures will rise measurably. At 2000m: -8 to -1 degree. Strong NE winds at high altitudes.

The fresh snow and drifts remain prone to triggering. Avalanche danger levels are not expected to change significantly.
