Bangladesh’s flood forecasting authority has warned of short-term flooding in seven districts across Sylhet and the north as river levels rise following heavy rainfall at home and upstream in India.

The Flood Forecasting and Warning Centre (FFWC) of the Bangladesh Water Development Board (BWDB) said in its Saturday bulletin that the Kushiyara River was flowing 1cm above the danger level at Fenchuganj in Sylhet.

Low-lying areas along rivers in Sylhet and Sunamganj districts could face short-term flooding within 72 hours, it warned.

The Teesta at Dalia point in Nilphamari, the Surma at Markuli point in Sunamganj, the Kushiyara at Moulvibazar point on the Sherpur-Sylhet stretch, and the Someshwari at Kolmakanda point in Netrokona are all flowing at warning levels.

In the north, the Teesta and Dharla rivers in Rangpur division have held steady since Friday while the Dudhkumar has receded—but all three could rise again over the next three days, potentially breaching danger levels.

Low-lying riverbank areas in Nilphamari, Lalmonirhat, Kurigram, Rangpur, and Gaibandha districts may then see short-term flooding.

Heavy to very heavy rainfall has been recorded over the last 24 hours in Sylhet Division and upstream in India’s Meghalaya and Arunachal Pradesh.

Weather agencies are forecasting heavy to very heavy rain over the next five days across Rangpur, Sylhet, and Mymensingh divisions and upstream in West Bengal, Assam, and Meghalaya.

The Brahmaputra-Jamuna river system has been rising for the past 24 hours and may continue to do so for five days.

Between Jun 30 and Jul 2, the Brahmaputra and Jamuna could reach warning levels in Kurigram, Gaibandha, Jamalpur, Bogura, Sirajganj, and Tangail districts, with some low-lying areas likely to flood.

In the northeastern basin, the Kushiyara River rose while the Surma ebbed over the same period, though both are predicted to climb over the next three days.

Water levels of the Khowai and Someshwari rivers in the Sylhet and Mymensingh divisions recorded a rise, while the Manu and Dhalai rivers dropped.

The Sarigowain and Jadukata rivers remained stable but are expected to swell over the next three days.

The FFWC cautioned that the Someshwari River may run near its warning line in Netrokona, temporarily flooding some adjacent low-lying areas.
