Heavy monsoon rains triggered deadly floods and landslides, with 16 districts warned of flash flood risks as major rivers rise.
Bangladesh has been severely affected by flash floods and landslides caused by heavy monsoon rainfall, with the Disaster Management and Relief Ministry reporting 51 deaths and over 1 million people affected since early July 2026. The crisis has particularly impacted districts in Chattogram and Sylhet divisions.
The Flood Forecasting and Warning Centre (FFWC) has issued warnings for at least 16 districts where major rivers including the Teesta, Dharla, and Dudhkumar are experiencing significantly rising water levels. These rivers may cross danger levels within 24 to 48 hours, potentially flooding low-lying areas across northern districts including Lalmonirhat, Nilphamari, Rangpur, Gaibandha, and Kurigram.
The Bangladesh Meteorological Department had warned of potential short-term flooding throughout July despite anticipating normal rainfall for the month. The warning followed a dry June that recorded 29.4 percent less rainfall than average. Heavy rainfall of 200 to 500 mm was recorded in some districts during the peak period.
As of mid-July, approximately 267,918 families were reported marooned across seven districts. The FFWC noted that five major rivers were flowing above their respective danger levels at seven monitoring stations. Authorities continue to monitor the situation closely as the monsoon season progresses.
