Rush of hill water and heavy rains have generated flash floods in vast regions of Bangladesh's Sunamganj region.
The Surma River was flowing 57cm above the danger mark near the district, said the Flood Control Cell of Sunamganj Water Development Board (WDB).
Floodwater swallowed low-lying areas in Sunamganj, Sadar and Tahirpur sub-districts or upazilas, leaving 500 families stranded, reports the Daily Star.
Biswambharpur, Doarabazaar and Jamalganj upazilias were also hit by the floodwaters five days back.
If the rain continues, the water level would cross the danger level at different points within 72 hours, said Saud Ahmed, executive engineer of WDB.
Debojit Singha, additional deputy commissioner (revenue) of Sunamganj said that they had informed the higher authorities in advance about the issue.
