Rescuers in Italy reported a deadly week in the country’s mountainous regions, where at least a dozen skiers, climbers, and hikers lost their lives in avalanches triggered by unstable snow conditions. According to authorities, 11 of the 12 victims were killed on ungroomed backcountry slopes, while The Associated Press noted a total of 13 fatalities.

The fatal incidents coincided with the start of the Winter Olympics last Friday. Officials emphasized that Olympic venues, including sites in Lombardy, Cortina d’Ampezzo in Veneto, and Val di Fiemme in Trentino, remain secure, closely monitored, and unaffected by the backcountry dangers.

Italy’s National Alpine and Speleological Rescue Corps explained that persistent weak layers in the snow, often covered by fresh snow or wind, make avalanches highly unpredictable. Even the passage of a single skier or climber can trigger a deadly slide.

Over the weekend, Vigili del Fuoco, Italy’s national fire and rescue service, reported two deaths and one serious injury in an avalanche at Alpe Meriggio in Valtellina. Additional fatalities occurred in Trentino, South Tyrol, near the Marmolada glacier, along the Apennines, and in Valle d’Aosta.

Authorities stressed that those skiing within managed resorts face minimal risk. Catania said, “There is no danger for people skiing within managed ski resorts, and, in particular, no risks to the Olympic sites. All of these areas are constantly monitored and are generally safe regardless of Olympic events.”

Ahead of the Milan Cortina 2026 Winter Games, Vigili del Fuoco said enhanced rescue structures and safety measures are in place to protect athletes, spectators, and the public while maintaining regular services.

The series of avalanches highlights the ongoing hazards of backcountry skiing in the Alps and Apennines, even as Italy continues to host the international sporting event safely.
