Avalanche Activity

Main problem: persistent weak layer

Avalanche danger levels above the treeline are moderate, below that altitude danger is low. Avalanches of medium size can be triggered even by minimum additional loading in some places above the treeline, in gullies and bowls in all aspects. Danger zones increase in frequency with ascending altitudes. Above 2000m, avalanches can also trigger in more deeply embedded layers of the snowpack and grow to medium size, particularly on W/N/SE facing slopes. Due to solar radiation, naturally triggered, usually small loose-snow avalanches can be expected on extremely steep sunny slopes.

Snowpack Structure

The snow has been transported far-reachingly. Exposed ridges and crests are windblown, gullies, bowls and slopes near forest rims are filled with snow. Above 2000m the snowpack layering is generally unfavorable, several weak layers are evident with faceted crystals. Especially on north-facing slopes the covered surface hoar is prone to triggering.

Weather Forecast

Nocturnal skies will be star-studded, mostly without high fog. Winds will be light everywhere. At 2000m: between 3 and 5 degrees; at 3000m: between -2 and 0 degrees. On Friday, radiantly sunny weather will continue, local high-fogbanks in the valleys will soon disperse. Winds light to moderate. At high altitudes, very mild. At 2000m: +5 degreese; at 3000m: -1 degree. Skies on Friday night will again be cloudless and have only light winds
