Special Correspondent – Heavy to very heavy rainfall is projected to batter various parts of Bangladesh, including Dhaka, Chittagong, and Barisal divisions, over the next four days.
The Bangladesh Meteorological Department (BMD) alongside the Flood Forecasting and Warning Centre (FFWC) issued severe alerts on Wednesday, warning that prolonged downpours are likely to deteriorate ongoing flood situations and submerge fresh low-lying areas across several northeastern and southern districts.
The monsoon season has intensified across Bangladesh, with the capital city Dhaka and multiple regions experiencing persistent rainfall since Wednesday.
According to official meteorological forecasts, this spell of wet weather is anticipated to last until Sunday, marginally lowering daytime temperatures while keeping nighttime conditions relatively unchanged.
As heavy rains continue to lash the country, major river systems are already swelling, pushing water levels above critical danger marks in several northern and northeastern stations.
According to the FFWC’s latest bulletin, the Kushiyara and Someswari rivers are currently flowing above their respective danger levels. Specifically, the Kushiyara River is flowing 35 cm above the danger mark at Fenchuganj in Sylhet and 2 cm above at Markuli in Sunamganj.
Meanwhile, the Someswari River has crossed the danger threshold by 5 cm at Kalmakanda in Netrokona. Although the Surma River at Sunamganj’s Chhatak station has temporarily receded below the danger level, the relief may be short-lived.
Weather agencies predict intense rainfall through Friday, particularly in the Chittagong and Barisal divisions.
This is expected to push water levels in the Surma-Kushiyara river systems even higher over the next 48 hours, creating short-term flood situations in the low-lying adjacent areas of Sylhet and Sunamganj.
Furthermore, the Atrai River in the Rajshahi division is rising rapidly and is projected to cross danger levels within two days, threatening to inundate low-lying regions in the Naogaon district.
In the south, while the Muhuri, Feni, Halda, Sangu, and Matamuhuri rivers are currently showing a receding trend, the FFWC warns that the Sangu and Matamuhuri rivers could hit warning levels within two days.
This poses a significant risk of temporary flash floods in parts of Bandarban, Cox’s Bazar, and Chittagong districts.
Looking at the country’s major river basins, the Brahmaputra remains relatively stable, but the Jamuna, Ganges, and Padma rivers are on the rise. River levels in Kurigram, Gaibandha, Jamalpur, Bogra, Sirajganj, and Tangail are expected to reach warning levels soon.
Conversely, while the Teesta and Dudhkumar rivers in the north have seen slight declines, they are forecasted to approach alert thresholds today, potentially causing temporary inundations in Lalmonirhat, Nilphamari, Rangpur, Gaibandha, and Kurigram.
Amidst these widespread warnings, Netrokona stands as the lone exception, with the current flood situation expected to improve slightly.
With a four-day heavy rainfall forecast threatening to overwhelm major river systems, Bangladesh faces an imminent risk of localized and short-term flooding.
Government authorities, disaster management teams, and local administrations in vulnerable districts—particularly Sylhet, Sunamganj, Naogaon, and the coastal belt—must remain on high alert to mitigate damage, protect infrastructure, and support affected communities in low-lying zones.
