Storm Nils is impacting the western coast of France, leading Meteo France to issue a red alert for the departments of Gironde and Lot-et-Garonne. The storm is expected to cause substantial and prolonged flooding along parts of the Garonne River, prompting warnings for residents in these areas. As heavy rains are set to persist until Thursday, authorities advise caution and preparedness for potential evacuations.

Forecasts from the Vigicrues organization predict that overflow from the Garonne could be exceptionally severe starting late Wednesday into Thursday, with water levels anticipated to surpass those seen during the significant floods of January 2022 and to be comparable to the disruptive floods of February 2021. This dire outlook underscores the seriousness of the situation, urging local authorities to be on high alert and communities to stay informed.

Additionally, the Aude department has also been placed under a red alert due to severe wind risks associated with the storm. This multifaceted weather event emphasizes the vulnerability of southwestern France to severe weather patterns, and it's crucial for both individuals and families in these regions to remain vigilant as the storm progresses and continue to monitor updates on safety measures and potential evacuations.
