Level 4 Wet Avalanche Danger Issued Across European Alps as Spring Snowpack Becomes Unstable - SnowBrains

"Avalanche forecaster Matthias Walcher explained that water is now penetrating deep into the snowpack, weakening long-standing weak layers that formed earlier in the winter. This process significantly increases the likelihood of spontaneous wet avalanches, particularly on steep west-, north-, and east-facing slopes between 2,200 and 2,500 meters."

"Security Councillor Astrid Mair urged extreme caution, warning that 'the avalanche situation is dangerous' and that steep terrain above 30° should be avoided entirely. She added that avalanches may travel far beyond typical boundaries, noting they may run into snow-free terrain and valley floors."

Avalanche warnings have been issued across the Alps, particularly in Switzerland and Tyrol, where conditions are deemed critical. The SLF has identified Upper Valais as a hotspot for both wet and dry avalanches. In Tyrol, the snowpack has become saturated, leading to Level 4 warnings for several mountain groups. Authorities advise avoiding steep terrain and caution that avalanches may travel beyond typical boundaries. Water penetration into the snowpack is weakening layers, increasing the risk of spontaneous wet avalanches on steep slopes.
