A looming crisis of flash floods has been identified across multiple regions in Bangladesh due to a combination of persistent heavy rainfall and massive runoff from upstream Indian territories. According to the latest update from the Flood Forecasting and Warning Centre (FFWC), the country is bracing for a critical 72-hour window where water levels in numerous rivers are expected to surge significantly.
High-Risk Regions Identified.
The FFWC has explicitly warned that the current weather pattern poses an immediate threat to the north-eastern, eastern, south-eastern, and northern regions. The areas projected to face the highest risk of short-term flooding due to river water crossing the danger level include:
Sylhet Division: Sylhet, Sunamganj, Moulvibazar, and Habiganj.
Mymensingh Division: Netrokona, Sherpur, and Mymensingh.
Chattogram Division: Chattogram city, Feni, Cox's Bazar, Khagrachhari, and Bandarban.
Rangpur Division: Nilphamari, Lalmonirhat, and Kurigram.
Additionally, authorities have specifically highlighted that the Teesta River could breach its danger levels within the next 24 to 48 hours. Several other critical rivers, including the Surma-Kushiyara, Gomti, Muhuri, Feni, Sangu, Matamuhuri, Dudhkumar, and Dharla, are also experiencing rapid increases in water flow.
Why is the Water Rising?
The current escalation is primarily attributed to a persistent low-pressure system over the Bay of Bengal, which has been fueling relentless rain for nearly three days. Rainfall intensity has been record-breaking in some parts; notably, Chattogram recorded a staggering 394 millimetres of rainfall within a single 24-hour period ending yesterday.
The situation is further exacerbated by extreme precipitation in upstream Indian regions like Meghalaya and Tripura. As heavy rainfall is forecasted to persist until Saturday, the threat of continuous mountain runoff remains a major concern for lower-lying Bangladeshi districts.
Outlook for the Coming Days
Sardar Uday Raihan, Executive Engineer at the FFWC, explained the projected timeline for this event:
The risk of flash flooding is expected to persist for the next three days.
Current data indicates that major rivers are still flowing below danger marks, providing a temporary buffer.
A gradual improvement in the flood situation is anticipated starting from Saturday onwards.
Despite the temporary buffer provided by current river flow levels, the forecast for the next four days indicates continued heavy-to-very-heavy rainfall across the Chattogram, Sylhet, Mymensingh, and Rangpur divisions. Residents in these vulnerable zones are urged to remain vigilant and stay updated with official meteorological bulletins.
