Eastern Bangladesh experienced two severe floods in August 2024 and July 2025, causing extensive damage and affecting millions. In July 2025, heavy rainfall caused rivers such as the Muhuri and Gomati to exceed safe levels, resulting in significant flooding. This study combines weather models, satellite imagery, and field surveys to analyze the causes and impacts of these floods. Despite forecasting efforts, communities were not fully protected, emphasizing the urgent need to enhance and localize Early Warnings for All (EW4All) to deliver timely and effective alerts to vulnerable populations. The floods disrupted infrastructure, agriculture, and power supplies, demonstrating the necessity for improved communication and community engagement. Strengthening localized warning systems, especially in transboundary river regions, alongside advanced technology and enhanced data sharing, will enable faster responses and better recovery from future floods.
