Water levels of the Brahmaputra-Jamuna river systems continued to rise while the overall flood situation in the Ganges basin remained steady on Wednesday.
The rise in Brahmaputra-Jamuna river systems was due to unremitting onrush of water from the upper catchment areas in Brahmaputra basin during the last 24 hours ending at 9am on Wednesday.
Officials of Bangladesh Water Development Board (BWDB) said water levels of major rivers might continue to rise during the next 48 hours in the river basin.
A bulletin of the Flood Forecasting and Warning Center (FFWC) of BWDB on Wednesday forecast that water level of the Teesta might rise rapidly during the next 12 hours and cross the danger mark (DM) at Dalia point for a brief moment in Nilphamari district.
In the upstream of the northwestern Indian states, the recorded rainfalls during the past 24 hours till 9am were 51mm at Gangtok, 34mm at Silchar and 33m at Darjeeling points.
However, no notable rainfalls were recorded during the period in the downstream areas of the Brahmaputra basin except 36.7mm at Jamalpur and 10mm at Dewanganj points in Jamalpur district, the FFWC bulletin said.
During the last 24 hours till 9am on Wednesday, water levels of the Dharla rose by 24cm at Kurigram, Ghagot by 18cm at Gaibandha, Brahmaputra by 27cm at Noonkhawa and 23cm at Chilmari and Teesta marked fall by 8cm at Dalia and 54cm at Kawnia points.
