Bangladesh warns of heavy rain, potential flooding in north and northeast

Northern and northeastern Bangladesh face the threat of heavy to very heavy rainfall over the next five days, according to a special weather bulletin from the Flood Forecasting and Warning Centre (FFWC). The bulletin, issued by the Bangladesh Water Development Board (BWDB), warns of cumulative rainfall potentially reaching 250-300mm in isolated areas of Sylhet and Rangpur divisions between June 8 and June 13.

This intense precipitation is also expected in adjoining upstream Indian regions, including Assam, Meghalaya, and West Bengal. Consequently, major river basins in Bangladesh's north and northeast are forecast to experience significant water level increases. The Surma and Kushiyara rivers in Sylhet are expected to rise steadily between June 8 and June 11, possibly reaching warning levels and creating short-term localized flooding risks.

In the Rangpur division, the Teesta, Dharla, and Dudhkumar rivers are also projected to swell. The Teesta river, in particular, is likely to approach alert thresholds in Lalmonirhat and Nilphamari districts. Data from the BWDB indicates recent rises in several rivers, though they remain below danger levels.
