Flood forecasters warned on Monday about flooding in the country’s three major river basins — Ganges, Brahmaputra and Meghna — at the end of the week or early next week because of cross-border heavy rains.
The rivers in the basins may cross their danger marks at places from Wednesday, said a Flood Forecasting and Warning Centre special flood outlook.
The rivers are already filled to the brim, unusual for this time of the year, because of continued heavy rains inside Bangladesh and in upstream across the border since May 20.
The River Teesta already crossed the danger level once two days ago but fell below the danger level immediately after and continued to flow with strong currents, washing away 263 houses since Sunday.
‘The water level in Brahmaputra-Jamuna may start rising rapidly from Wednesday and it may keep swelling for the next ten days,’ said the special flood outlook.
It may cause short to medium range flooding in Kurigram, Bogura, Jamalpur, Gaibandha, Sirajganj, Tangail, Manikganj and Pabna districts, said the forecast.
The FFWC predicted that the Jamuna river might cross the danger mark at Bahadurabad and Sirajganj on Saturday.
The Teesta and Dharla rivers may cross their danger marks at a number of places leading to flooding after June 24, said the forecast.
The Padma may cross the danger mark at Goalondo on June 29, according to the forecast.
The rivers in Meghna basin such as Surma, Kushiyara, Sarigowain, Jadukata, Someswari, Kangsha, Manu and Khowai may cross their danger mark at places depending on rains over the next week, said the FFWC forecast.
In its daily forecast the FFWC said that 54 gauging stations saw rivers swelling out of 101 stations across the country in 24 hours till 9:00am on Monday.
The FFWC daily report showed that many places in Ganges and Meghna basin already received more than normal rainfall for the month while some places in Eastern Hill Basin received nearly double the normal rainfall.
Bangladesh is no stranger to monsoon floods but it could get damaging to economy if it stays for long.
The likelihood of floodwaters staying long increases when flood discharge reaches peak in three major river basins around the same time.
