“Lump Risk” : the snowpack is prone to triggering - brilliant and fine weather - high likelihood of avalanche releases involving persons! Caution urged particularly in Tirol’s western regions above 2400 m.
Once the clouds and the fogbanks have dispersed, particularly in the northern regions, Christmas Day according to ZAMG Weather Service will be brilliantly beautiful. In the western regions where there has been 30 to 50 cm of fresh snow registered above 2400 m since 23.12, locally more, we now have a treacherous situation: “winter-sports high” avalanche danger. Atop an often weak old snowpack there is now fresh snow deposited, winds and warmth have formed a pronounced slab. For tomorrow, 25.12, we foresee an extremely trigger-sensitive snowpack in very steep terrain above 2400 m (the rainfall level over recent days). Increasingly on W/N/E facing slopes and in general near ridgelines. On south-facing slopes the snowpack is prone to triggering only in high alpine regions. Even remote triggerings are possible because the slab is so pronounced. Therefore: keep distances, especially on very steep W/N/E facing slopes at high altitude. Especially on north facing slopes.
