Severe winter storms brought extreme snowfall across the French Alps over the past week, forcing widespread closures of ski resorts, transport networks, and mountain roads as authorities raised avalanche danger to the highest level and urged the public to limit travel in several alpine regions including Chamonix, Savoie, and Haute-Savoie.
The disruptions intensified on 12 Feb. 2026 after local tourism officials in Chamonix warned that heavy snow accumulation and unstable mountain conditions would continue to restrict access to major ski areas, suspend public transport services, and shut key routes connecting high-altitude communities.
Resorts and Transport Systems Largely Shut Down
Multiple ski destinations across the French Alps suspended lift operations and closed slopes as avalanche risk reached Level 5, the maximum on the European danger scale. Major resorts in Savoie, including La Plagne and Les Arcs, halted nearly all skiing activities as fresh snowfall added to already unstable snowpacks formed by repeated storms.
In the Chamonix Valley, authorities restricted access to upper mountain sectors including Les Grands Montets, Brévent, Flégère, and Balme-Le Tour. Only limited lower-altitude beginner areas remained open, while off-piste and mountain activities were strongly discouraged.
Transport disruptions extended beyond ski infrastructure. Several departmental mountain roads were closed as a preventive measure, reducing access to higher villages and resort areas. Rail service on the Mont Blanc Express line was reduced, and local ski bus routes serving upper valley sectors were suspended or operating on limited schedules.
Officials cited heavy overnight snowfalls combined with strong winds as the main factors creating unstable layers prone to large natural avalanches, particularly at higher elevations and on steep slopes.
Storm System Brings Widespread Safety Concerns
The recent weather system delivered intense snowfall across much of southeastern France, with some alpine areas recording accumulations of tens of centimeters in a short period. Emergency services increased patrols and conducted preventive avalanche-triggering operations where possible, though visibility and ongoing snowfall limited some control efforts.
Local authorities placed several mountain communities on heightened alert, warning of possible large avalanches capable of reaching valley floors, infrastructure corridors, and forested zones near transport routes.
In addition to resort closures, some schools and municipal services in high-altitude towns operated on reduced schedules due to road inaccessibility and safety risks.
Weather services forecast continued unsettled conditions across parts of the Alps, with further snowfall at elevations before a gradual stabilization later in the week, though avalanche danger is expected to remain elevated even after the storms subside.
Tourism officials advised travelers to monitor official resort updates, avoid non-essential mountain travel, and follow local safety instructions closely until conditions improve.
The French Alps are among Europe’s busiest winter tourism regions, attracting millions of international visitors each season. The current closures are among the most extensive weather-related disruptions of the winter to date, affecting holiday travel plans, resort operations, and regional transport links.
Authorities emphasized that while heavy snowfall benefits long-term ski conditions, rapid accumulation combined with wind-driven drifting significantly increases avalanche risk, making temporary shutdowns necessary to prevent serious accidents.
Resort operators said reopening decisions would depend on stabilization of snow layers, successful avalanche control work, and improved weather visibility over the coming days.
