Between Ötztal Alps and Ortler Massif, sunny mountain weather; in the other ranges, still fogbanks. East of the Karwendel as far as the Kitzbühel Alps and in the Tux Alps, light snowfall repeatedly over the day, bringing no large amounts. Tuesday night, clear and cold. Temperature at 2000m, -16 degrees; at 3000m, -19 degrees. Moderate NE winds, brisker in the Northern Alps. Snow Layering The automated weather stations make clear that the wind has shifted to N/NE and is well above transport strength in many places. Thus, new, brittle and thus, trigger-sensitive snowdrifts will accumulate. Potential weak layer: loose, drifted-over powder snow. Other potential weak points occur inside the old snowpack, beginning on shady slopes above 1900m, above 2300m in the other aspects. The problem is the loose, faceted-crystal snow and depth hoar which lies wedged between several thin or less-thin crusts. Stability tests have shown a high proneness to triggering. The zone around 1900m also evidences blanketed-over surface hoar. Avalanche Danger Avalanche danger remains as it was: above the treeline considerable danger prevails, below the treeline moderate danger. The situation in southern East Tirol where there is far less snow is more favourable. Danger zones occur where there are fresh snowdrift accumulations,but also where the old snowpack is prone to triggering. Fresh drifts occur primarily above the treeline near ridgelines on E/S/W slopes, they are brittle due to the low temperatures, easily triggered even by one sole person. The old snow problem is more difficult to spot; it begins on shady slopes above 1900m, above 2300m on west and east facing slopes, above 2600m on south facing slopes. A slab can be triggered even by minimum additional loading there, then sweep the snowpack down to ground level layers with it, thus growing to large-sized avalanches. We advise enormous restraint on steep, shady slopes where the problem threatens most.
