National

At least eight rivers of the county were flowing above their danger levels on Saturday morning, with the Atrai and Titas showing an upward trend.

The water levels of all other major rivers in the country including the Surma and Kushiyara were falling, according to a bulletin of the Flood Forecast and Weather Centre (FFWC).

The Atrai was flowing above the danger level with a 3cm rise at Baghabari in Sirajganj.

The Titas also saw a rise in Brahmanbaria by 4cm.

At least 13 districts are experiencing monsoon floods as of Saturday morning, with over 5 million marooned in Sylhet division since June 15. Standing crops in the districts have also been damaged by the floods.

The health authorities have documented 73 flood-related deaths since mid-May.

The FFWC said the rivers in Sylhet, Sunamganj and Netrokona might fall in the 24 hours to 9am on Sunday, while the water levels of rivers in Kishoreganj and Brahmanbaria districts might remain unchanged.

On Saturday morning, the Surma and Kushiyara rivers were still flowing above their danger marks.

In the next 48 to 72 hours, there is a chance of medium to heavy rainfall in the sub-Himalayan West Bengal (Jalpaiguri, Sikkim). As a result, the water level of the Teesta River may rise and remain near the danger level.

However, the flood situation in Kurigram, Gaibandha, Bogra, Sirajganj, Tangail and Jamalpur may improve in the next 24 hours.

There is a chance of short-duration floods in the low-lying areas of Rajbari, Shariatpur and Madaripur in the next 24 hours, according to the FFWC.

Tetulia upazila of Panchagarh saw the highest rainfall in 24 hours to Saturday morning, record at 54mm. 

In general, 50mm or more rainfall in one day causes stress on the local drainage system leading to localized flooding, according to the FFWC. Meanwhile, 300mm or more rainfall in 10 consecutive days impedes the drainage and is likely to cause rain-induced flood in the area.
