Red Alert Maintained in Loire-Atlantique as Loire River Hits Record Levels
NANTES, 20 February 2026 – The Loire-Atlantique department remains under a state of maximum vigilance this Friday as western France grapples with a historic hydrological crisis. Following a record-breaking streak of 35 days of rainfall, the Loire river reached a peak of 8.17 metres in Nantes yesterday, the highest level recorded in the city since 2010.
Emergency Response and Evacuations
Météo-France has maintained the “Red Alert” (Vigilance Rouge) for Loire-Atlantique, alongside Maine-et-Loire and Charente-Maritime. The prefecture confirmed that emergency services have conducted over 124 interventions across the department. Approximately 50 households have been relocated to emergency shelters, and six motorists were rescued after becoming stranded on flooded roads.
The situation was exacerbated by the arrival of Storm Pedro, which brought high winds and additional precipitation to already saturated soils. Local authorities have taken the strategic decision to allow certain secondary roads along the riverbanks to flood intentionally to alleviate pressure on urban flood defences.
Impact on Infrastructure and Transport
The flooding has caused significant disruption to regional infrastructure. Several major road axes are currently closed to traffic, and SNCF has reported delays and cancellations on rail lines connecting Nantes to Angers and Saint-Nazaire. In Nantes, the “Loire Estuaire” section remains under intense monitoring as high tides continue to influence water levels downstream.

Environmental and Safety Warnings
Authorities have issued a stern warning to residents to avoid all non-essential travel near watercourses. A search is currently underway for a man reported missing in the Loire river; officials have urged the public not to approach the banks, as the current remains extremely powerful and unpredictable. While forecasters suggest a “calm weekend” may be approaching, the Vigicrues monitoring service warns that river levels will remain high for several days due to the massive volume of water moving downstream from the Loire basin.
