Overview
- Météo-France kept Gironde under orange flood vigilance for Wednesday and downgraded Charente-Maritime to yellow.
- Vigicrues reports maximum spring tide coefficients of 99 with surge and river flow propagation set to raise levels most at Wednesday morning’s high tide.
- Levels in Bordeaux and Libourne are expected to match Tuesday morning’s readings with damaging overflows possible, particularly at the confluence.
- In Bordeaux on Tuesday, the Garonne spilled onto left-bank quays near the Pont Chaban-Delmas, and flooding was also reported at Langoiran.
- Municipal measures include vehicle relocations and access restrictions in risk zones, with closures in Arcachon and a bridge closure in Portets, as saturated catchments heighten responsiveness.
