Severe Snowstorm Paralyzes Île-de-France with Record Traffic Jams and Transport Disruptions

On January 5, 2026, a heavy snowstorm swept across Île-de-France, causing unprecedented disruptions to traffic, public transport, and air travel, alongside administrative safety responses.

Traffic congestion reached a historic peak, with over 1,000 kilometers of jammed roads reported by late afternoon, surpassing previous regional records. Motorists faced significant delays, with some journeys commonly taking 30 to 40 minutes extending to over 1.5 or 2 hours. Authorities imposed an 80 km/h speed limit across main roads and banned heavy vehicles over 3.5 tonnes from major routes to improve safety and mobility.

Public transport services were heavily affected. The RATP suspended all bus operations from 4 PM due to icy and hazardous conditions, and significant delays hit train services, including wait times of up to three hours on lines from Gare Saint-Lazare and disruptions on RER A and B lines. Despite these challenges, metro lines continued running.

Air travel also experienced notable impacts, as the aviation authorities mandated a 15% reduction in flight schedules at Paris-Charles de Gaulle and Orly airports to address weather-related safety concerns. This led to average delays of 50 minutes at Roissy and 37 minutes at Orly.

Safety measures extended to schools, with transport for students suspended in several departments including Seine-et-Marne, Oise, Yvelines, Normandy, Brittany, and others. Early school dismissals were also ordered in certain towns, prompting parents to adjust their plans amid the disruption.

The Paris police activated Level 3 of the Snow and Ice Response Plan, enforcing restrictions on vehicle circulation and urging the public to limit travel and plan early returns home. Complementing these efforts, over 1,250 additional emergency shelter places were opened in Paris to support those vulnerable during the cold snap. Temperatures were expected to remain low with further snowfall forecasted, particularly in northern and western France regions.

Despite the chaos on roads and transit, the snowfall transformed the Parisian landscape, captivating residents with its picturesque charm. However, officials and commuters remain cautious as the cold weather conditions continue to challenge the daily commute and safety.

This multi-faceted disruption highlights the significant effect of extreme winter weather on one of France's busiest regions, prompting coordinated responses across transportation, education, and public safety sectors.
