Otherwise, sunshine reigns. This afternoon, some cloud will enter the picture. Mild: zero-degree level at 2500-3000m. Temperature at 2000m, +4 degrees; on the southern flank of the Alps +1 degree; at 3000m, -2 degrees. In high alpine regions and in foehn-exposed terrain, strong southwesterly winds; elsewhere, usually blowing at moderate strength. Snow Layering The single overriding aspect of recent days has been wind, wind and more wind. Huge snow plumes at the mountaintops were clear indicators of wide ranging snow transport. For that reason the snowpack is distributed highly irregularly, the surface extremely varied. Below about 2600m the surface is frequently covered by ice crusts. The loosely packed, faceted crystals between the embedded crusts in all aspects (primarly above approximately 2100m) are seminally weak layers; on shady slopes they occur as far up as 2600m. The huge temperature contrasts inside the snowpack can also cause new weak layers to form near the uppermost surface. Avalanche Danger Avalanche danger in Tirol remains delicate far and wide above approximately 2100m, the danger level is considerable. Below 2100m two perils threaten: a) the old snowpack is prone to triggering above approximately 2100m. Particularly in transition areas from shallow to deep snow, even minimum additional loading can trigger a slab avalanche in steep terrain. In isolated cases, remote triggerings are still possible at any time, particularly in high alpine regions in all aspects; between 2100 and 2600m on shady slopes. b) Avalanches can fracture at the transition point between the fresh fallen snow and the loosely packed powder beneath it. This particularly threatens above approximately 2300m. And with ascending altitude, the likelihood of such freshly formed snowdrift masses triggering increases.
