Already flooded this year, people in the lowlands and haor areas of Sunamganj are seeing fresh flooding again due to heavy rainfall and water from upstream.
The Surma river was 17cm above the danger mark at Shologhar point and the Jadukata River was flowing 23cm above the danger mark in Bishwamvarpur upazila at 9am on Friday.
The district water development board has recorded 183mm of rainfall in the last 24 hours.
Floodwaters have started to enter the lowlands of Dowarabazar upazila and the haor areas of Bishwamvarpur upazila, affecting livestock and damaging crops and roads.
Meanwhile, local administration has continued distributing dry foods, safe drinking water, and corrugated iron sheets to 42,057 flood-affected families in 11 upazilas and four municipalities of the district.
Sunamganj Water Development Board Executive Engineer Sabibur Rahman said water from upstream, doubled by heavy rainfall in the district, has induced fresh flooding in the already flood-affected lowlands and haor areas.
Earlier, both Bangladesh and Indian meteorological offices predicted heavy to very heavy rainfall in the next 72 hours in northeastern Bangladesh and the adjoining Indian northeastern states of Assam, Meghalaya, and West Bengal.
