Loss of snowpack firmness due to rain

Loss of snowpack firmness due to rain

Avalanche danger is LOW. On extremely steep (>40°) slopes esp. below 1600 m, naturally triggered avalanches can release in isolated cases, most are wet loose-snow or glide-snow releases. At high altitudes isolated danger zones due to fresh snowdrifts on N/NW facing slopes and in gullies.

Atop a well-settled but thoroughly wet old snowpack, 10 cm of fresh snow is expected to fall. This will bond with the fundament well except at high altitudes, where thin drifts will be generated by intensifying foehn wind.

In early morning and for a few hours there will be light snowfall on the Main Alpine Ridge and vicinity, clouds will remain dense. The snowfall level will ascend from 1000 to nearly 1600 m during the day. At 2000 m: -3 to +1 degree; at 3000 m: -8 to -4 degrees. Southerly foehn wind will be blowing at 40-60 km/h.

On Friday, temperatures will rise further amid southerly foehn winds, the zero-degree level will ascend to 2500 m. Recent fresh snow will moisten, further naturally triggered wet loose-snow avalanches will trigger in the old snow.
