Avalanche Activity

Wet loose-snow avalanches possible (small-to-medium)

Avalanche danger is subject to a daytime danger cycle. In morning danger is low, then rises swiftly with the increasing temperatures to moderate. Danger zones for dry-snow slab avalanches lie above 2000 m. Danger zones are particularly in steep ridgeline terrain and laterally wind-loaded slopes (discontinuities, precipices), esp. steep north-facing slopes, releases usually from large additional loading, but also possible from one person. The danger of moist loose-snow and slab avalanches increases during the course of the day. In extremely steep terrain, naturally triggered releases are possible.

Snowpack Structure

During the nighttime hours the snowpack regains stability. A melt-freeze crust usually forms on the surface. In morning it loses this firmness, the snow becomes moist-to-wet. Older dry snowdrift accumujlations still occur above 2000 m on north-facing slopes. Older drifts are not bonded with the old snowpack.

Weather Forecast

Sunny and warm on Saturday, in afternoon some convective cloud build-up. Brisk SW foehn winds. At 2000 m: 2-5 degrees.

Tendency

On Sunday the early summer weather will return to the mountains of Styria. Sunshine, only high-altitude clouds and blue skies. The SW winds will intensify to moderate in afternoon, brisk in places. Daytime danger cycle needs attentiveness.
