Somewhat warmer in the mountains than in the valleys during the morning. Temperature at 2000m: -6 to -1 degree; at 3000m, -8 to -5 degrees. Moderate southerly winds, blowing at brisk to strong velocity in the classic foehn lanes. Snow Layering The major problem continues to be the strikingly weak ground-level layers inside the snowpack. It affects shady slopes above 2000m most of all. It consists of faceted-crystal snow and/or depth hoar which lies embedded between a series of crusts, all of which is deeply embedded. On sunny slopes, the problem begins above 2300m. In addition, snowpack analysis has revealed the danger patter cold-atop-warm on sunny slopes. The faceted-crystal layer on sunny slopes is particularly acute at altitudes of about 2500m. On sunny slopes, the snowpack surface usually has a thin melt-freeze crust, on shady slopes there is still good powder. Avalanche Danger The danger in Tirol is dependent on region and altitude. West of the Kitzbühel Alps, considerable danger reigns above about 2000m; elsewhere the danger is generally moderate, beneath 2000m it is often low. What is most treacherous about the current situation is the striking old-snow problem. This affects more than anywhere else steep, shady slopes above 2000m where slab avalanches can be triggered even by minimum additional loading; in isolated cases can be remotely triggered even from flat terrain. The old-snow problem also affects sunny slopes, begaining at about 2300m, on south-facing slopes at about 2600m. Particularly the shallow-snow spots in very steep terrain can release slab avalanches. Generally at the present juncture, large additional loading is necessary to fracture avalanches down to ground level layers; these can grow to dangerously large size. In high alpine regions, caution urged towards the small-sized, freshly-formed snowdrift masses near ridgelines on very steep, shady slopes. In addition, snow on steep, grass-covered slopes can slide away in gliding avalanches. These are frequently ‘announced’ by glide cracks on the surface.
