Snowpack Structure

The S/W winds have transported the fresh snow of Monday and Tuesday. The drifts lie deposited atop a weak old snowpack surface. There is a loose layer inside the fundament which is a potential weak layer. Blanketed surface hoar and faceted crystals are weakening the snowpack fundament.

Weather Synopsis

On Tuesday night a bit of rainfall/snowfall is anticipated, between Turracher Höhe anda Koralpe, up to 15 cm is expected. The snowfall level lies at valley floor. Wednesday: the snowfall will taper off in the morning. In the afternoon clouds will disperse and some sunshine is expected. Westerly winds will reach speeds of 30-50 km/hr. At 2000 m: -8 degrees.

Tendency

It will remain cold, avalanche danger levels are not expected to change.

Avalanche Activity

Snowdrift problem. Caution urged towards fresh cornices.

Avalanche danger levels in the Gurktal and Seetal Alps, on Stubalpe and on Koralpe are considerable. Fresh snowdrifts on north-facing slopes are the main danger. Avalanche prone locations are found near ridglines and at entries into gullies and bowls. Triggering a slab avalanches is possible even by minimum additional loading. Above the treeline on shady slopes, large-sized avalanches can be triggered. Caution urged towards fresh cornices, they are easily triggered.
