Problemi valanghivi

  • Persistent weak layers

    • Tutte le quote

Tendency

Some fresh snow and wind will generate a slight snowdrift problem. Avalanche danger levels will rise slightly.

Snowpack Structure

The snowpack fundament is still shallow, often not cohesive. Due to a sequence of melt-freeze crusts and soft layers with faceted crystals, there is a persistent weak layer in places. Atop of that lies 20-40 cm of soft, bonded snow which is often blanketed by a melt-freeze crust or is moist. Only in shady terrain at high altitude is there still powder to be found. Below 1500 m in the northern regions of Styria, there is still no area-wide snowpack fundament.

Avalanche Activity

Few danger zones: in shady high-altitude terrain, moderate danger

In the western Northern Alps above the timberline, moderate avalanche danger prevails. In few danger zones, additional loading can trigger slab avalanches. The avalanche prone locations are found on extremely steep entry points into gullies, shady slopews, bowls and are difficult to recognize. On extremely eteep slopes small loose-snow avalanches can trigger. At low altitudes, avalanche danger is low.

Weather Synopsis

All day Friday, skies will be overcast, temperatures at 2000 m will drop from +2 to -6 degrees. In the evening, light snowfall will set in, winds shift to westerly. On Saturday, temperatures will drop another notch, skies in the morning will be heavily overcast, a bit of snowfall is possible. During the daytime hours, clouds will disperse but it will remain cold. Sunday will be bitter cold but beneath brilliantly blue skies.
