Small drifts in high alpine regions. Danger: taking a fall on hard snowfields.
First things first: strong winds are generating mostly small, often trigger-sensitive snowdrift accumulations at high altitudes. Caution urged especially on shady, steep slopes. A cold front on 19-20. November brought generally 10-20 cm of fresh snow, locally a bit more. Fresh snow: 19-20.11.2020 Plus, in major areas of precipitation along the Main Alpine Ridge, strong…

First snowpack analysis results – Ongoing old snow problem in high alpine regions – Heed temporary snowdrift problem
Snowpack analysis in high alpine terrain Since our last blog we have swooped far and wide in the state helicopter, dug deep in the high altitude snows in order to construct snow profiles of Tirol’s high alpine terrain. Part of this involves snowpack stability tests in order to find out how well the disparate layers…

Avalanches from north-facing high-altitude upper weak layers
Avalanches involving persons Since last Sunday (3 May), four avalanches have been registered in which persons were involved. Initial analyses show that recently generated upper-level weak layers combined with snowdrifts deposited on top of them were the main cause of these releases. The weak layers formed due to danger pattern 4 (cold on warm) and…
