Continuous rainfall and hill runoff from India’s Meghalaya have caused a rapid rise in river water levels across Sunamganj district. Several low-lying areas have already been inundated, with reports of roads and markets going underwater. The Anwarpur–Sunamganj road in Tahirpur is submerged, and water has entered parts of Sadar, Dowarabazar, Tahirpur, and Bishwambharpur upazilas. The Khasiamara River has overflowed into nearby localities, affecting villages along the haor regions.

According to the Water Development Board, water levels in the Surma, Boula, Jadukata, and Rakti rivers have risen significantly, with the Surma River increasing by 64 centimeters in 24 hours. Although still 60 centimeters below the danger level, officials warned that continued heavy rain over the next two days could push it to or above that threshold. Executive Engineer Mamun Hawlader stated that if rainfall persists for 48 hours, flooding in low-lying areas is likely.

The district administration has taken precautionary measures, advising residents near rivers and haors to stay alert and prepare essential documents, dry food, and emergency supplies in advance.
