Poor visibility due to fog and snowfall. Drifting at high altitude. In the Dolomites and Carnic Alps, bright intervals. On the East Tirolean Tauern Ridge, light snowfall. Temperature at 2000 m, -8 degrees, at 3000 m, -13 degrees. Brisk to strong-velocity NW winds. Snow Layering The most important factors to keep in mind today are the coming snowfall together with wind; and the surface hoar, which was observed particularly in fog-influenced regions and which extends from the valley floor to above the treeline, particularly in northern and eastern regions. It is also there where the heaviest snowfall is expected today: about 20 cm in western regions, as much as 40 cm in eastern regions. Surface hoar will then form a potential weak layer which will be extremely prone to triggering. Furthermore, new snowdrifts will form above the treeline. They will be deposited on a snowpack surface generally riddled with faceted snow crystals. Particularly on shady slopes and in general at high altitudes, they will be quite trigger-sensitive. Avalanche Danger The strong winds combined with the snowfall which has already commenced are causing a sharp spike in avalanche danger. Above the treeline predominantly moderate, elsewhere low danger is expected to rise during the course of the day as snowfall becomes more widespread. In northern and the furthermost eastern regions of Tirol, where the heaviest snowfall is expected, danger may rise to considerable this evening. This is also due to the blanketed surface hoar, making the snow masses especially easy to trigger. Elsewhere, most of the danger stems from freshly formed snowdrift accumulations, found mostly above the treeline on shady, very steep slopes and at high altitudes in general near ridgelines. In addition, observers have reported increasingly frequent gliding snow masses in the western regions in particular.
