Weather Synopsis

Tendency

No significant change expected.

Avalanche Activity

Icy NE winds

Avalanche danger is LOW. Only very few danger zones exist: in extremely steep terrain and shady high altitude slopes where fresh shallow snowdrifts have been generated. Isolated small-to-medium glide-snow avalanches are possible, triggering naturally. Zones below glide cracks and extremely steep grassy slopes should be avoided.

Snowpack Structure

Most surfaces have enormous wind impact and are hardened. Where there is no wind there are a few centimetres of fresh snow atop a springlike surface (melt-freeze encrusted). Also the layers of the old snowpack are well bonded, though there are icy films between them. The weakest layer lies at ground level. At valley floor and on sunny slopes there is little snow up to intermediate altitudes.
