Overview
- Météo-France is keeping both departments on red flood alert through Tuesday as Vigicrues flags a likely new rise driven by fresh rain focused on the southwest and the Pyrenees.
- Nearly 1,600 residents have been evacuated across Gironde and Lot-et-Garonne since Thursday, including large preventive movements after levee failures in Aiguillon where three dikes broke.
- After weekend peaks—about 9.56 m at Tonneins, 10.34 m at Marmande and 9.85 m at La Réole—the river edged down Monday to roughly 9.05 m at Tonneins and 9.37 m at Marmande, with evolution still uncertain.
- Infrastructure remains strained with about 35,000 electricity customers still off supply and roughly 21,000 internet outages reported, while many roads and several bridges stay closed.
- Boat crews continue rescues and supply runs to isolated neighborhoods around Marmande as prefectures caution that a second crest is possible by midweek.
