As flood waters recede in the northeast districts, major rivers are swelling in the northern districts.
Levels of the water in the Teesta, the Dharala and the Dudhkumar rivers will rise rapidly if it rains upstream, said a bulletin of the Flood Forecasting and Warning Centre (FFWC) yesterday.
"The Brahmaputra-Jamuna and the Ganges-Padma rivers are in a rising trend, which may continue in the next 48 hours," said the bulletin released at 9:00am.
As water levels in major rivers fall in the north-eastern region, flood waters are receding in Sunamganj and Netrokona districts, it added.
Besides, major rivers in the northeastern region of the country are in a falling trend except Khowai, Someswari and Dhalai, which may continue over 48 hours, the bulletin said.
The ongoing flood situation in Sunamganj and Netrokona districts may remain unchanged in 24 hours, it said.
In Lalmonirhat, the Teesta inundated the low-lying areas yesterday morning and continued to flood new areas.
People were seen commuting on boats as roads went under water.
According to media report, the swelling water of the Teesta river has crossed the danger level due to the onrush of water from upstream on Wednesday. The water of the river is flowing three cm above the danger level at Dalia point in Nilphamari district.
At 6 am at Dalia Point of Teesta Barrage, water flow was recorded at 52.18 cm, which is flowing 3.3 cm above the danger level.
Water Development Board authorities opened 44 sluice gates of Teesta Barrage to control the water flow.
In Bogura, the Jamuna has been swelling rapidly since Monday, and if it keeps this rate, some areas may get inundated, said BWDB Executive Engineer Nazmul Haque, adding that a major flood in the next 15 days was unlikely.
In Netrokona, the Someshwari was still flowing 31cm above the danger level at 9:00am.
According to Water Development Board Dalia Division, on June 19, the water of the river crossed the danger level. After a day the water started to recede. Later, it was normal but on Wednesday the water rose again.
As a result, some Chars in the lower part of Teesta river in Dimla and Jaldhaka upazilas have been flooded. However, as the water flow is not permanent, there is no possibility of damage, BWDB officials added.
BWDB Dalia Division executive engineer Asfauddaula Prince said, 'The people on the banks of the river have been made aware with the help of the local administration. If there is any problem anywhere, the Water Development Board is ready to deal with it.'
Dimla upazila nirbahi officer Belayet Hossain said the local people in the area have been warned by the public representatives and the village police.
