Severe flooding in central Bangladesh (13–15 May 2026) driven by pre-monsoon rainfall and Himalayan snowmelt threatens millions across the Ganges–Brahmaputra delta.
🌊 OPEN LIVE 3D WEATHER ALERTSA severe flooding event is unfolding across central Bangladesh from 13–15 May 2026, centred near coordinates 25.122°N, 90.34°E in the Dhaka region. Heavy monsoon precipitation and upstream river discharge have triggered widespread inundation, threatening communities across low-lying deltaic plains. Real-time data from GDACS confirms active flood progression, with displacement and water-borne disease risks escalating rapidly across affected districts.
Bangladesh's vulnerability to flooding stems from its geography: the nation occupies the world's largest river delta system, where the Ganges, Brahmaputra, and Meghna rivers converge before emptying into the Bay of Bengal. During the pre-monsoon season (May–June), upstream snowmelt from the Himalayas combines with intense tropical rainfall, overwhelming floodplain capacity. The delta's extremely low elevation (many areas <1 metre above sea level) provides no natural drainage buffer, enabling water to spread rapidly across agricultural lands and settlements.
Pandita Data integrates NOAA precipitation radar, NASA river discharge models, and ESA Sentinel satellite imagery to monitor flood extent in real time. Satellite reflectance data distinguishes water-inundated pixels from dry land, updating every 6–12 hours to track flood progression across villages and cropland. Hydrological models assimilate upstream discharge measurements to forecast peak flood levels and duration.
Over 80% of Bangladesh's landmass is floodplain. Annual monsoon floods displace 1–5 million people. Climate-driven sea-level rise and delta subsidence (3–4 mm/year) are worsening inundation depth and duration, compounding humanitarian risk.
