Avalanche Activity

Caution on north-facing slopes: persistent weak layer. Local snowdrift accumulations in E/S aspects.

Avalanche danger south of Mur and Mürz Rift is low. Isolated danger zones are located on extremely steep slopes in northern aspects. Older snowdrift accumulations can be triggered by large additional loading. Due to rising NW winds, small snowdrift patches can form on east-facing and south-facing slopes. Caution near ridgelines!

Snowpack Structure

The snowpack was able to settle. The old snowpack at high altitudes is being weakened by faceted crystals near melt-freeze crusts. Elsewhere the snowpack is hard and icy. Some snowdrifts have been deposited atop a hardened surface and/or surface hoar at high altitudes.

Weather Synopsis

The NW air current will persist. South of the Niedere Tauern there will be less snow than in the Northern Alps. Northern foehn wind will make it sunnier here. Temperature at midday at 2000 m: -14 degrees. The NW winds will reach speeds of 80-110 km/hr in exposed terrain.

Tendency

South of the Niedere Tauern on Saturday there will be less snowfall, least of all in the Koralm region (only 5 cm). A slight rise in avalanche danger levels is expected in the Gurktal and Seetal Alps.
