The Jamuna, swollen by the rising waters of the Brahmaputra in its upstream, may worsen the flood situation in Jamalpur, Bogura and Gaibandha in the next 24 hours, the Flood Forecasting and Warning Centre (FFWC) warned yesterday. The water level of the Jamuna has been on the rise for the past few days. The river rose yesterday in Fulchhari area and threatened the lower parts of the district. It was flowing a little below the danger level (DL) in the afternoon, said Arifuzzaman Bhuiya, executive engineer of FFWC.

The Jamuna threatens Kurigram and parts of Gaibandha and Jamalpur every monsoon when it rains heavily in its upstream. Besides the low-lying areas of Jamalpur, the fury of the Jamuna is likely to impact the low-lying areas of Sirajganj downstream. However, its ferocity will subside in the next few days, Bhuiya said.

Sources at the Met office in Dhaka have said the monsoon has become less active with the advent of autumn. Even though it will become active again in a few days, its impact would lessen, they added.

The monsoon in the first week of October will behave normally and then depart. The total rainfall recorded this month until yesterday was 5,808 mm, indicating it would remain normal, Ruhul Kuddus, a meteorologist, said.

Meanwhile, there had been no rainfall in the country till 12 noon yesterday, which is why the temperature soared. The maximum temperature recorded in the country was 36 degrees Celsius in Bhola. Dhaka received no rainfall till 6am. The temperature rose to 35.2 degrees Celsius from Saturday’s 34 degrees Celsius.
