Extremely heavy snowfall is expected in the mountains. Mountain weather today: North Tirol’s peaks all the way to the East Tirolean Tauern are shrouded in fog today, it is snowing. Towards the Lechtal Alps and the Arlberg, snowfall will be intermittently intense this morning. In the course of the afternoon, the snow showers will slacken off as temperatures drop and gusty winds increase, there will be interims of tranquility, even occasional sunny spells in between. From the Ortler and Dolomites southwards, visibility will be quite good, accompanied by next to no snowfall whatsoever. Temperature at 2000 m: minus 6 degrees; at 3000 m: minus 13 degrees. Strong, gusty westerly to northwesterly winds at high altitudes. The westerly to southwesterly winds yesterday attained the strength needed to transport the snow, giving rise to new, relatively small snowdrift accumulations. These drifted masses of snow have generally been deposited on top of cold, loosely packed fresh fallen snow. Thus, the bonding is inadequate, making them quite prone to triggering. The old snowpack has by now settled well and is relatively stable. However, caution is urged towards one prevalent weakness: the fundament on shady slopes above approximately 2500 m (in other aspects above approximately 2800 m) frequently consists of loosely packed, unbonded depth hoar. The avalanche danger level in Tirol’s backcountry touring regions is considerable widespread above approximately 2200 m. The major peril stems from freshly formed, generally small sized accumulations of snowdrift. This drifted snow is poorly bonded with the new fallen snow lying directly beneath it, making it relatively easy to trigger as avalanches: no more than minimum additional loading is necessary, i.e. the weight of one single backcountry skier or freerider. Backcountry skiing and freeriding tours in outlying terrain away from secured ski runs require extensive experience in evaluating avalanche dangers. Below about 2000 m, naturally triggered full depth snowslides are still possible in isolated cases.
