Bangladesh: Flash Floods - Jul 2026

A monsoon depression persisting over south Jharkhand and adjoining Odisha, India, combined with a strong active monsoon current over the North Bay of Bengal, is bringing heavy to very heavy rainfall to Cox's Bazar, Bandarban and Chattogram districts from 6 to 9 July 2026. [...] In the 24 hours to 6:00 AM on 7 July, BMD recorded 283 mm of rainfall in Chattogram, 195 mm in Kutubdia, 129 mm in Cox's Bazar and 128 mm in Bandarban, indicating that the heaviest rainfall band has shifted north into Chattogram while remaining severe across all three districts.

[...] In the early hours of 6 July, three separate landslides struck Rohingya refugee camps (FDMN) in Ukhiya upazila Jamtoli Camp-15, Kutupalong Camp-7 and Balukhali Camp-11 killing eight people, including five children, when hillsides collapsed onto shelters built on unstable slopes. A ninth person died in a separate landslide in Cox's Bazar municipality. [...] With rainfall intensifying and risk levels rising across all three districts, the cumulative toll has continued to climb: as of 7 July, 10 fatalities and 88 injuries have been recorded across 170 weather-related incidents since 5 July, and the potential for further casualties and damage remains high over the coming days as forecasted.

The monsoon depression and subsequent heavy rainfall have created a district-wide humanitarian situation affecting both the Rohingya camps and host communities in Cox's Bazar.
