Persistent weak layers
- All elevations
Caution urged in northern aspects: persistent weak layer. Local snowdrift accumulations.
On Thursday a cold front will force temperatures lower, bring storm-strength winds and snowfall. South of Mur and Mürz Rift only a little snowfall. Temperature at midday at 2000 m: -7 degrees. The NW wind will reach speeds of 80-120 km/hr in exposed terrain.
No significant change in avalanche danger levels.
Caution urged in northern aspects: persistent weak layer. Local snowdrift accumulations.
Avalanche danger south of Mur and Mürz Rift is low. Isolated danger zones are located on extremely ssteep 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.
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.
