Rising water levels in major rivers and forecasts of heavy rainfall may trigger flashflood in at least 16 districts, according to the latest Flood Forecasting and Warning Centre (FFWC) bulletin.
Water levels in the Teesta, Dharla, and Dudhkumar rivers have risen significantly over the past 24 hours and are expected to continue increasing for the next two days, said the FFWC bulletin.
These rivers could cross the danger level within 24 to 48 hours, triggering flood in low-lying areas of Lalmonirhat, Nilphamari, Rangpur, Gaibandha, and Kurigram.
In the northeast, the Surma River has continued to rise, while the Kushiyara River has shown a slight recession.
However, both rivers are expected to rise again over the next three days, and the rivers may exceed danger levels in parts of Sylhet and Sunamganj, potentially worsening the ongoing flood situation.
Several other northeastern rivers, including the Sarigowain, Jadukata, Jinjiram, Someshwari, Bhugai, and Kangsha, are also rising. The Bhugai, Kangsha, and Someshwari rivers may cross the danger level in Sherpur, Mymensingh, and Netrokona, while the Sarigowain and Jadukata rivers could overflow in Sylhet and Sunamganj, leading to flashflood in nearby low-lying areas.
Meteorological agencies have forecast heavy to very heavy rainfall over the next 24 hours across the Rangpur, Rajshahi, Mymensingh, and Sylhet divisions, as well as adjoining upstream areas of Assam, Meghalaya, and West Bengal in India. The rainfall is expected to further aggravate river conditions.
The Brahmaputra-Jamuna and Ganges rivers have recorded rising water levels, while the Padma has remained stable.
These rivers are expected to continue rising over the next five days and may reach the warning level in parts of Kurigram, Gaibandha, Jamalpur, Bogura, Sirajganj, and Tangail within the next 24 to 72 hours, causing flashflood in adjacent low-lying areas.
Water levels in several rivers across the Rangpur and Rajshahi divisions, including the Upper Karatoya, Upper Atrai, Tangon, Punarbhaba, Mahananda, Jamuneshwari, Atrai, and Ghaghat, have increased and are likely to continue rising.
The Atrai and Chhoto Jamuna rivers may reach the warning level in Naogaon and Natore, increasing the risk of flashflood.
In Chattogram Division, the Sangu River has risen, while the Halda River has receded and the Matamuhuri River has remained stable.
Water levels in these rivers are expected to rise over the next day before increasing more rapidly during the following two days.
Authorities have urged residents in vulnerable low-lying areas to remain alert and follow official flood advisories as weather conditions continue to deteriorate.
