Heavy rushing water from upstream Indian states and continuous monsoon rain across Bangladesh have caused six major rivers to rise above their danger marks. This places millions of people at immediate risk of floods.

An urgent warning has been issued by the Flood Forecasting and Warning Centre (FFWC) on Thursday. Authorities said there is a high probability that heavy rain in the next two to three days will trigger new flash floods or aggravate the situation. The most vulnerable areas include districts in the Sylhet division, the Chittagong Hill Tracts and parts of northern Bangladesh.

Water levels have already crossed safe limits at several monitoring points along the Sangu, Matamuhuri, Manu, Khowai, Dhalai and Kushiyara rivers, said an official report signed by FFWC Assistant Engineer Mahmudul Islam Shovon. The weather forecast looks challenging, with heavy to very heavy rainfall expected across the Sylhet, Chittagong, Rangpur, Mymensingh, and Rajshahi divisions. Neighbouring Indian regions, including Tripura, Assam, Meghalaya, and West Bengal, are also expecting heavy rains, which will send more water down into Bangladesh.

Weather experts are closely watching the southern and hilly river areas. Over the next 24 to 48 hours, the Sangu and Matamuhuri rivers are likely to rise quickly. This could cause quick flash floods in Bandarban, Chittagong, and Cox’s Bazar districts. At the same time, rising water in the rivers of Feni, Khagrachhari, and coastal Chittagong might flood low-lying lands, while low areas in Lakshmipur and Noakhali could face temporary flooding.

In eastern Bangladesh, the ongoing flood situation in Moulvibazar and Habiganj is expected to remain stable but full of water. However, nearby districts—including Sylhet, Sunamganj, Netrokona, Sherpur, and Mymensingh—face a fresh risk of flooding in low-lying areas. Because the Surma and Kushiyara rivers are forecast to rise rapidly over the next three days, emergency officials worry that the flood situation in Sylhet and Sunamganj could get worse.

The risk is also moving toward the northern part of the country. The Teesta River is expected to rise over the next two days, which could cause short-term flooding in parts of Nilphamari, Lalmonirhat, and Rangpur. Nearby, the rising waters of the Dharla and Dudhkumar rivers are likely to temporarily flood low-lying areas in Kurigram and Lalmonirhat, adding more difficulties for farming communities during this monsoon season.
