Avalanche Activity

Trigger-sensitive snowdrift accumulations above the timberline

Avalanche danger above the treeline is moderate, below that altitude danger is low. Avalanche prone locations occur near ridgelines, behind abrupt disconuities in the terrain. This applies particularly to westerm aspects. In danger zones, slab avalanches can be triggered even by minimum additional loading ane, in places, grow to medium size.

Snowpack Structure

The fresh fallen snow of recent days has been able to settle. Strong easterly winds have done their work on the snowpack. Bonded snow lies atop cold and loose layers. As a result of rising temperatures the snowpack surface will become moist up to intermediate altitudes. On shady slopes, surface hoar formed on Tuesday and Wednesday.

Weather Synopsis

In the evening hours skies will still be overcast throughout Styria. In the north skies will gradually clear. On Wednesday, superb sunshine. Winds will be easterly. Along the rimline ranges, barrier clouds will accumulate, with fog. At 2000 m: -4 degrees.

Tendency

The snowpack will be able to settle somewhat.
