Overall Situation:
Since the onset of the monsoon season, Bangladesh has been affected by heavy flooding including tropical cyclone REMAL-24 on 27 May 2024 and since 28 May 2024, heavy rainfall in India's hill regions, particularly Meghalaya and Assam, has caused flash floods in North-East region of Bangladesh. While the situation was improving, from 16 June 2024, harsh downpours inside the country, as well as adjoining northeastern Indian states of Assam and Meghalaya, have further exacerbated the situation, leading to the second spell of devastating floods that severely impacted several upazilas in Sylhet and Sunamganj districts. Sylhet and Sunamganj districts have experienced 242mm and 223mm of rainfall which exceeded the monthly average seasonal rainfall of this region. Specifically, the Haor region has been affected by this heavy rain and heavy flooding was triggered between 20 and 25 June 2024 in the northeast, particularly flooding the Sylhet region. iThe northeastern region, including Sylhet, Sunamganj, Moulvibazar, Habiganj, Kishoreganj and Netrokona, is severely affected, impacting over 2.5 million people. Monthly rainfall averages have been exceeded in Sylhet and Sunamganj, leading to submergence in several sub-districts. Roads in various upazilas are submerged, disrupting communications, and both Sylhet City and Sunamganj town face significant waterlogging.
At the same time, around June 19th, 2024 flooding severely affected the northern part of Bangladesh, inundating the districts of Lalmonirhat, Kurigram, Gaibandha, Bogura, Sirajganj, Jamalpur, Tangail, and Munshiganj impacting a Total of 749980 people. The flood situation in Kurigram has worsened significantly, with water levels of the Brahmaputra River at Nunkhawa, Hatia, and Chilmari points, and the Jamuna River at Fulchhari point, rising above the danger level. This has impacted 18,709 families across 42 unions in 8 upazilas, affecting 84,252 people. A total of 26 shelters have been opened for 3,124 people and 660 livestock, and 83 medical teams are providing healthcare services.

Thirty-two shelters have been opened for 8,919 people and 2,835 livestock. Jamalpur is similarly affected, with the Jamuna River at Sirajganj 93 cm above the danger level and continuous rainfall exacerbating the situation which impacted 18,385 HHs and 83,152 individuals impacted in Sirajganj moreover, Flooding has impacted 47,532 HHs across 34 unions in 7 upazilas, affecting 2,03,028 people in Jamalpur.

In Bogura 26,550 HHs (101,132 individuals) have been affected in total. In Lalmonirhat 1,500 HHs which includes 7,500 Individuals stranded in flood water. Due to the severity of the Floods,
Educational Institutes are closed in some of the affected areas.
Rangpur, Thakurgaon, Rajbari, and Shariatpur are at a warning level due to the current rising water situation. A summary of the total affected individuals is given in below table:
Alongside around 18th and 19th June 2024, the flood situation in the southeastern part of Bangladesh including districts like Feni, Rangamati, Khagrachari, Bandarban, and Coxs Bazar have experienced significant flooding. In Khagrachari, areas like Dighinala have been cut off, affecting road connectivity and daily life, with several villages still submerged. In Rangamati's Baghaichari and Longadu Upazila, Dighinala (Khagrachhari) and Baghaichhari (Rangamati) critical infrastructures like schools, colleges, Post office and other Government offices were inundated, local markets are mostly non-functional for the time being. 400 families were relocated by Khagrachhari district administration anticipating potential landslides in Sadar areas. Outbreaks of water borne diseases are anticipated. However, diarrhea patients are increasing already. Due to continuous rain, the whole Cox’s Bazar camp settlement faced low-moderate rain with moderate gusts. Because of the squally weather conditions with rain, few landslides occurred in a few camps. Approximately Around 500 shelters were damaged. Due to heavy rain around 30 incidents were reported in the camp settlement affecting nearly 3,000+ individuals, with 0 casualties and injuries. As instructed by the Site Management and Camp in Charge/Assistant Camp in Charge risky HHs (who are living in vulnerable hill slope areas) were relocated to the nearest temporary cyclone centers/safer facilities (learning centers, nutrition facilities, and other facilities) by the CPP camp volunteers. Besides, trained CPP camp volunteers were involved in disseminating anticipatory actions including awareness messaging, continuously revisiting the identified landslide-prone areas/landslide inventories across the camps, ensuring safer relocation of the most vulnerable families, etc. iii Additionally, in the Feni district, broken river embankments have led to flooding, impacting over 13,000 people and necessitating significant relief efforts, including the distribution of rice and dry food.
In the upcoming forecast for Bangladesh, the Brahmaputra River's water level will gradually decrease over the next 24 hours, while the Jamuna River's level will remain stable. However, the Ganges-Padma River is expected to rise significantly in the next 72 hours, with the Padma River at Goalanda likely to surpass danger levels within 48 hours. In the northeastern region, water levels in major rivers are expected to decrease gradually, improving flood conditions slightly. Conversely, northern areas like Kurigram and Gaibandha may experience rapid rises in river levels, potentially worsening flood situations in those districts. Overall, moderate to heavy rainfall is anticipated in northern regions over the next day, contributing to varying flood dynamics across affected areas.
