From late May to early June 2025, Sylhet and surrounding districts in northeastern Bangladesh were affected by extreme rainfall. Approximately 405 mm of rain fell within 24 hours on 1 June, making it one of the heaviest downpours of the season.
This Copernicus Sentinel-2 image, acquired on 9 June 2025, shows extensive flooding across the region. In this false-colour composite, vegetation appears in red, while bodies of water and inundated areas are depicted in shades of blue.
Copernicus data is essential for rapid flood mapping and damage assessment. These observations support emergency response operations and inform long-term adaptation and resilience strategies.
