Wind slab

Due to fresh snow and moderate-velocity southerly winds, trigger-sensitive snowdrift accumulations have been generated esp. in ridgeline terrain, in gullies and bowls, esp. above 2400m. Avalanches can be triggered by persons in the uppermost layers. In addition, isolated avalanches can fracture down to deeper layers of the snowpack and then grow to medium size. In starting zones which have not yet discharged, mostly small wet loose snow avalanches are possible, and can be triggered by winter sports enthusiasts. Caution urged in extremely steep slopes below 2000m. In addition, in the major areas of precipitation, isolated mostly small glide-snow avalanches are possible esp. on extremely steep slopes.
Since Wednesday above 2000m, about 15-20 cm of fresh snow has been registered, locally more. Above 1600m 20-20cm of fresh snow still expected. Winds are transporting the fresh snow intensively. Fresh snow and drifts are being deposited on shady slopes above 2000m atop an unfavorable old snowpack surface (soft layers).
On Saturday, snowfall level will ascend to 1000m and by afternoon to 1400m. In exposed terrain, strong S/SW winds (60 km/hr). At 2000m: +1 degree in afternoon; at 1000m: 3 degrees.
Naturally triggered dry-snow avalanches will gradually decrease as the snowfall ends. Glide-snow avalanches can trigger at any time of day or night.
