New areas are going underwater every day as the water level continues to rise in the north while hundreds of thousands of people are stranded in floods in the northeast Sylhet region.
Incessant monsoon rains for the past few days have caused the inundation.
The Flood Forecasting and Warning Centre or FFWC said on Wednesday the rainfall might ease within the next three days.
The water level of the rivers Surma and Kushiara will also drop, and the flood situation will improve in the northeast then, according to the centre.
It said water was flowing above the danger level in seven points of the rivers Surma, Kushiara, Halda and Matamuhuri in Sylhet region until 9am.
Several hundred thousand people have been affected by the floods in Sylhet, Sunamganj, Habiganj, Moulvibazar and Cox’s Bazar districts since the beginning of this week.
The situation is worst in Moulvibazar, where more than 265,000 people are stranded. The district administration said 277 educational institutions have closed due to the flooding.
In Sylhet, floods have affected more than 100,000 people and forced closure of 200 institutions.
New areas were inundated in Habiganj and Sunamganj on Wednesday.
FFWC Engineer Sardar Uday Rahman said they observed a rising trend of water in 65 of the 90 points the centre monitors across the country.
The level was dropping in four points on the Kushiara but was still flowing 16 to 78 centimetres above the danger level until morning.
The Surma water dropped one centimetre in Sunamganj but was still five centimetres above the danger level.
In Sylhet’s Kanaighat, the water level of the Surma rose 15 centimetres in 24 hours until morning and was flowing 72 centimetres above the danger level.
The Halda water rose 45 centimetres and was flowing 10 centimetres above the danger mark at Narayanhat point in Chittagong. The water level of the Matamuhuri increased 37 centimetres at Chiringa point in the same region and was flowing 78 centimetres above the danger level.
In the northern districts, the water level of the rivers in the Brahmaputra-Jamuna and Ganges-Padma basins are rising due to flow from upstream India.
Water rose at most of the points in the two basins but did not cross the danger mark.
Engineer Uday Rahman said, “New areas in the northeast are being flooded. I hope the situation will improve when the water level of the Surma and Kushiara drops after two days.
“But the situation may continue to worsen to some extent in the other areas.”
Almost the entire country is experiencing moderate to heavy rains in the second half of Asharhh, the first month of the rainy season in Bangla calendar.
In the capital Dhaka, the Met office recorded 27 millimetres of rain between 6am and 6pm.
It said in Thursday’s forecast that light to moderate rain or thundershowers accompanied by temporary gusty wind is likely to occur at most places over Rangpur, Rajshahi, Dhaka, Mymensingh, Khulna, Barisal, Chittagong and Sylhet divisions.
Moderately heavy to very heavy falls are also likely at places over the country, it added.
Meteorologist Khandakar Hafizur Rahman told bdnews24.com that heavy rains in Chittagong and Sylhet divisions might trigger landslides in hilly areas.
“We’ll have to be alert to the threat,” he added.
