The flood situation worsened in the country's northern and northeastern regions on Friday due to heavy rainfall and onrush of water from the upstream in neighbouring India.
As major rivers started to cross the danger marks, low-lying and char areas got inundated in Nilphamari, Lalmonirhat, Gaibandha, Kurigram, Bogura, Tangail, Natore, Sherpur, Netrakona and Sunamganj districts, according to the Flood Forecasting and Warning Centre (FFWC).
Five rivers-Dharla, Jamuna, Gur, Jadukata and Surama-were flowing above the danger levels on Friday, said Arifuzzaman Bhuiyan, executive engineer of FFWC.
On Friday, the country's rivers were swelling in 56 points, out of 101.
The Brahmaputra and Jamuna rivers saw a rising trend which might continue today (Saturday) while the Ganges and Padma rivers might remain steady, said the FFWC.
The major rivers in the upper Meghna basin in the northeastern regions were also rising and the trend might continue today (Saturday), it said.
In Kurigram, recent rainfall and onrush of upstream water caused Teesta, Dharla and Brahmaputra rivers to burst their banks, inundating new char areas and leaving around 0.1 million people marooned in the last one and half weeks.
The Met office recorded heavy rainfall at Lorergorh in Sherpur (200 mm), Durgapur in Netrakona (116 mm), Jaflong in Sylhet (94 mm), Dalia in Nilphamari (85 mm) during 24 hours ending at 9:00 am on Friday.
The Met office forecast that moderate to heavy rain is likely to occur in most places of the country today (Saturday) as strong monsoon persists over the North Bay while a deep convection was taking place.
