Flooding Across Southern France and Corsica – Core Event
On Tuesday 20 October, a 75-year-old man was swept away by floodwaters in Saint-Mitre-les-Remparts, west of Marseille, and later found dead in the neighbouring commune of Istres, according to the Bouches-du-Rhône prefecture. A second fatality was confirmed on 21 October on the island of Corsica when a man in his 60s, whose vehicle was carried off by the river in Ghisonaccia, was recovered dead after being missing for several hours. The same storm also left one person missing in Ghisonaccia after a 4×4 was swept away.
Meteorological Background
Météo-France linked the episode to a cold low-pressure system named “Adam,” which produced torrential rain across the Mediterranean basin. Recorded totals included - 191 mm in one hour at the Solenzara airport (Corsica), - 315 mm at Saint-Chamas, - 279 mm at Salon-de-Provence, - 275 mm at Istres, and - 219 mm at Marignane. A weather station at Solenzara air base logged 612 mm in 24 hours, roughly five times the area’s average October rainfall.
Human Impact and Disruptions
The floods forced evacuations in Istres, where residents were moved to a sports hall, and in other affected towns such as Lunel, where about fifteen people were taken in by the municipality. Roads, motorways (including sections of the A55 and A9), and Marseille’s tram network were temporarily closed or suspended. Train services to and from Nîmes remained disrupted, and numerous vehicles were submerged up to their windows. Emergency crews deployed a civil-security helicopter for search-and-rescue operations and pumped water from inundated properties.
Official Responses and Weather Alerts
The Bouches-du-Rhône prefecture coordinated the rescue effort and confirmed the deaths. Météo-France issued orange weather warnings for the Var and Bouches-du-Rhône departments on 20 October, later reducing the number of orange alerts from nine to seven while maintaining yellow flood warnings for river flooding. Authorities advised motorists to avoid flooded roads, exercise caution, and allow extra travel time.
Outlook
Météo-France’s bulletin for Wednesday 21 October indicated that orange warnings would no longer be forecast for the Var or Bouches-du-Rhône, though yellow flood alerts could persist, meaning the risk of rising water levels may continue even after the heaviest rain has passed. Residents are urged to follow updates from Météo-France and local prefectures.
