Storm Nils Triggers Deadly Avalanches and Heightened Avalanche Warnings in French Alps

The French Alps have been severely impacted by Storm Nils, which brought heavy snowfall and led to a surge in avalanche risks, resulting in tragic fatalities and heightened safety warnings. On February 13, three skiers died in Val-d’Isère, Savoie, after being caught in a devastating avalanche in an off-piste area with a very high avalanche risk. According to official statements, six skiers were caught in the avalanche, including four accompanied by a professional guide. Despite all victims being equipped with avalanche victim search systems, three fatalities were confirmed. An investigation into the incident has been launched.

The region had seen substantial snowfall of 60 centimeters to 1 meter due to Storm Nils, accompanied by a rare red avalanche alert issued by Météo-France for Savoie—only the third such alert in 25 years. Avalanche risk levels remain high at 4 out of 5 in most Alpine massifs. Météo-France warns that the snowpack is unstable, particularly above altitudes of 1,800 to 2,000 meters, making avalanches easily triggered by skiers or hikers and posing dangers with large snow volumes.

In the Isère department, vigilance orange for avalanches in the Oisans and Grandes Rousses mountain ranges was lifted on the morning of February 13, replaced by yellow vigilance. Nonetheless, the avalanche risk remains high (level 4/5). Forecasts indicate up to 1 meter of snowfall above 2,000 meters and 30 to 40 cm around 1,500 meters. Safety recommendations from authorities emphasize limiting travel, avoiding off-piste skiing, using avalanche safety equipment such as beacons, shovels, and probes, and not venturing alone. Authorities urge regular monitoring of updates via official websites.

Following the fatalities and ongoing high avalanche risk, several ski areas have implemented partial or full closures as a precaution. The current weather conditions combined with the heavy snow from Storm Nils present persistent hazards across the French Alps, underscoring the critical importance of adhering to safety advisories and avoiding risky mountain activities in unstable areas.
