Avalanche Activity

Few danger zones in extremely steep terrain

Avalanche danger is LOW. There are only few small danger zones due to fresh snowdrift accumulations in extremely steep ridgeline terrain and in gullies, where releases are possible from one sole person. Outside of that, low danger from naturally triggered glide-snow avalanches which can release at any time of day or night in extremely steep zones which have not yet discharged. In case of solar radiation, the latest bout of fresh fallen snow can release naturally as a small superficial loose-snow avalanche.

Snowpack Structure

Atop a thoroughly wet isotherm old snowpack surface a few cm of settled snow lies deposited, depending on altitude, which is melt-freeze encrusted. In exposed terrain, shallow drifts lie deposited, generated by W/N winds. No weak layers, only the fundament shows weakness.

Weather Synopsis

Wednesday will be sunnier than Tuesday, but for a few convective clouds in the afternoon with some visibility reduction at high altitudes. However, it will remain dry. The NW winds will be be light to moderate, brisker in the Tauern in the early part of the day. At 2000 m:- 9 to -7 degrees.

Tendency

On Thursday no significant change expected.
