Caution: foehn-induced snowdrifts

Avalanche danger above 2000m is MODERATE, below that altitude danger. Snowdrift accumulations near to and distant from ridgelines on north and east-facing slopes can trigger a small-to-medium slab avalanche, in some steep places even by minimum additional loading. Above 2200m, isolated weak layers in the old snowpack can be triggered and avalanches can become correspondingly larger. Most dangerous of all are transitions from shallow to deeper snow and entries into gullies filled with drifts. Isolated glide-snow avalanches and small wet loose-snow avalanches can trigger naturally.

The border to the old snowpack can be a weak layer for a slab avalanche. In additional, above 2200m there are several weak layers in the old snow, of faceted crystals which are often prone to triggering.

Visibility is generally good, only in the Lungau will clouds be heavier. The southerly foehn wind will often be brisk. At 2000m: -2 to +4 degrees.

On Thursday night a cold front will bring strong-velocity W/NW winds and some snowfall. Fresh, shallow snowdrift accumulations can be freshly formed.
