DHAKA – The Flood Forecasting and Warning Centre (FFWC) this evening issued a special outlook warning that short‑term and flash floods could hit at least ten districts in the northern and northeastern regions within the next 24 to 48 hours.
According to the FFWC, heavy to very heavy rainfall inside Bangladesh and across upstream Indian states — including Assam, Meghalaya and West Bengal — has caused a rapid rise in major river levels.
At present, two major rivers are flowing above danger marks at three stations. In Sylhet, the Kushiyara is 18cm above its danger level at Chhatak and 33cm above at Fenchuganj. In Netrokona, the Someshwari has breached its danger limit by 19cm at Kalmakanda, inundating low‑lying areas.
Water levels of the Surma and Kushiyara are projected to swell further over the next three days, worsening conditions in Sylhet and Sunamganj. The Sarigowain and Jadukata rivers are also rising, heightening the risk of short‑term inundation. The Bhugai, Kangsha and Someshwari are expected to worsen flooding in low‑lying areas of Sherpur, Mymensingh and Netrokona within 48 hours.
In the north and northwest, the Teesta, Dharla and Dudhkumar rivers are rising significantly. The Teesta is already at its warning level at Dalia, Kaunia, Tarapur and Haripur stations. Within 24 to 48 hours, these rivers may cross danger marks, causing sudden flash floods in Lalmonirhat, Nilphamari, Rangpur, Gaibandha and Kurigram.
Concurrently, the Brahmaputra–Jamuna river system is on a steady five‑day upward trend. The Brahmaputra is at its warning level at Chilmari station in Kurigram. Within 24 to 72 hours, the system is expected to reach warning limits at multiple points, threatening low‑lying regions in Kurigram, Gaibandha, Jamalpur, Bogura, Sirajganj and Tangail.
In Rajshahi division, the Atrai and Chhoto Jamuna rivers are projected to temporarily submerge low‑lying areas in Naogaon and Natore within three days.
FFWC Executive Engineer Sardar Udoy Raihan confirmed that heavy upstream and domestic rainfall over the next 24 hours poses a flash‑flood risk for adjacent low‑lying areas of the aforesaid districts in Rangpur, Rajshahi, Sylhet and Mymensingh divisions.
While conditions in parts of Sylhet may deteriorate over the next two days, he assured there is no possibility of major or prolonged flooding at this time.
