DHAKA, June 5, 2024 (BSS) - The week-long flood that engulfed much of Sylhet causing huge sufferings of people as flood water is receding slowly from low-lying areas causing suffering of thousands of people.

"Improvement pace of Sylhet flood is very slow as north-eastern districts of Bangladesh and upstream regions of India witnessed incessant rainfall in the past 24 hours," Sub-Divisional Engineer of Flood Forecasting and Warning Centre (FFWC) Sajal Kumar Roy told BSS today.  

Hilly regions of both Bangladesh and India is experiencing excessive rainfall impacted by tropical cyclone Remal that hit Bangladesh coastline on May 26, he said adding "Cyclone Remal  took more time for making landfall, which caused a record-breaking rainfall across Bangladesh and some states of India that cause flash flood in Sylhet."

Analyzing mathematical rainfall model, the hydrologist predicted hilly areas of north-eastern parts of the country may witness more rainfall as cyclone Remal carrying huge moisture while crossing Bangladesh.

Heavy to very heavy rainfall is likely in the hilly regions of both Bangladesh and India as water vapour has converted into rainfall in Sylhet and its adjacent district Sajal said adding as monsoon is set early this year as under the influence cyclone Remel.

Pre-monsoon rains, triggered by cyclone "Remal", flooded wide swaths of Sylhet since late May affecting over seven lakh people, officials and residents said.
 
"Ten upazilas out of 13 under Sylhet district including city corporation areas were badly affected by flash flood due to onrush of water from upstream regions of Indian states - - Assam, Tripura and Meghalay," Deputy Commissioner of Sylhet district Sheikh Rasel Hasan said.

He said, "As many as 7,39,362 people under 10 upazilas of Sylhet have been severely affected by this year's first flash flood forcing local administration to take urgent measures to deal with the overall flood situation."

As part of the all-out efforts, Sylhet district administration has set up 571 shelter centres for flood-hit people, Hasan said flash flood damaged some infrastructures including roads, bridges and houses under five upazilas close to Indian borders.

Standing crops under 10 upazilas of Sylhet were also damaged by flood as low-lying areas in the district are still under flood water, residents and official concerned said.

Flood water submerged 24 wards of Sylhet City Corporation, they said adding overall flood situation is improving very slowly as most areas of Sylhet regions witnessed heavy rainfall in the past 24 hours.

Sajal acknowledged that rainfall across Sylhet region also contributed to the flash flood as almost the entire country experienced incessant rainfall due to the influence of cyclone Remal.
