"AvalancheSwiss federal authorities have declared the highest possible avalanche danger level-Level 5-for several regions of the canton of Wallis/Valais, warning of an "extraordinary avalanche situation" following heavier-than-expected snowfall overnight. The Level 5 alert applies to the regions of Val d'Entremont-Val Ferret, Emosson, Conthey-Fully, Montana, Leukerbad-Lötschental, Riederalp and Konkordia. Cantonal officials say the combination of massive fresh snowfall and strong winds has created highly unstable conditions across large swaths of the southern Swiss Alps."
"Level 5 is the most severe rating on Switzerland's five-step avalanche danger scale. It signals that: Numerous very large natural avalanches are expected Extremely large avalanches are possible Avalanches may release deeper layers of the snowpack Typical avalanche paths may extend to unusually low elevations Exposed transportation routes and settlements are at risk The SLF reported that more snow fell overnight than originally forecast. Combined with wind-drifted snow, the fresh accumulations are described as "very prone to triggering.""
Several regions in the canton of Valais were placed at Level 5 avalanche danger after heavier-than-expected overnight snowfall combined with strong winds produced highly unstable snow conditions. Many very large and extremely large spontaneous avalanches are expected, with slides able to exceed known paths and potentially reach valley floors, threatening roads and settlements. Level 5 indicates avalanches may release deep snowpack layers and extend to unusually low elevations. Surrounding areas are at Level 4 "High" danger, where large amounts of fresh and wind-drifted snow remain prone to triggering and dangerous for exposed routes.
