Farmers are worried as parts of north-eastern haor region received heavy rains on Thursday as forecasted earlier with the possibility of heavy rains causing flash floods in the area.
‘Parts of Sylhet experienced rains on Thursday but we have no way of confirming the intensity of it because we have no weather station where it rained,’ said meteorologist Nazmul Haque.
Nazmul said that he believed that rains were less intense than had been predicted.
On Thursday, a Flood Forecasting and Warning Centre bulletin said that there was no possibility of flash flood anywhere in the northeastern region until 9:00am on Friday.
The FFWC recorded rise in water levels in 26 rivers out of the 39 river stations monitored during the 24 hours until 9:00am Thursday.
The FFWC said that major rivers in north-eastern region would continue to swell over the next three days because of heavy rains predicted in Bangladesh and Assam and Meghalaya in the upstream.
An Institute of Water and Flood Management assessment showed that 11 rivers in the haor region might overflow at 18 places from Friday and that some of the rivers might continue to flow above their danger levels throughout the last week of the month and into the first few days of the next month.
The rivers likely to overflow are Kalni, Khowai, Kushiyara, Titas, Surma, Dhalai, Jadukata, Manu, Sarogowain, Jhalukhali and Sutang.
‘Surma, Khowai and Dhalai are more likely to overflow than the other vulnerable rivers,’ said professor AKM Saiful Islam of the Institute of Water and Flood Management under the Bangladesh University of Engineering and Technology.
‘The next three days are crucial for the main spell of rains is likely to stretch over the days,’ he said.
On Thursday, Indian Meteorology Office in a bulletin predicted widespread to fairly widespread rainfall in Assam and Meghalaya and West Bengal and Sikkim until Monday.
Heavy rain in Indian upstream is particularly a matter of headache for Bangladesh at this time of the year for boro production.
The haor region accounts for nearly a fifth of the country’s two crore tonnes of boro production, roughly half of which is usually ready to be harvested by April.
The other half of boro rice is not ready to harvest until May. The total boro acreage in the haor region is about 4.5 lakh hectares.
The harvest in the haor region had a slow start this year with an acute shortage in the supply of farm hands because of restricted movement in the wake of coronavirus crisis.
Bangladesh could not yet harvest half the boro ready to be reaped in the haor region.
