Heavy monsoon rains fell across Bangladesh and India in early May 2025, triggering severe flooding in parts of Bangladesh by the middle of the month. Then a deep depression formed over the Bay of Bengal and made landfall near the West Bengal-Bangladesh coast of May 29, bringing extreme rains and strong winds—and worsening the flooding in eastern regions of the country where at least 66,000 people were affected.
According to ReliefWeb, the worst affected areas include Sylhet, Sunamganj, Moulvibazar, Habiganj, Netrokona, Noakhali, Bhola, Khagrachari, Bandarban, and Rangamati. This includes damage to thousands of shelters in refugee camps and more than 1,400 homes. The report identified that one refugee was killed as a wall collapsed and at least eleven more were injured.
On June 10, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this false-color image showing extreme flooding across Bangladesh. This type of image helps separate areas covered by water, which appears deep blue, from vegetated areas, which show up as bright green. Clouds look white, except for high, cold clouds that contain ice which may be tinted with light blue. The flooding primarily covers Bangladesh, but some extends into western India. In addition, the Brahmaputra River is in flood stage in both countries.
To help visualize the impact of the floods, the June 10 image can be compared to a second Aqua MODIS image of the same area acquired on May 9. At that time, the rains had just begun to fall and no flooding was occurring. To compare the images, simply click on the dates.
