Real-time coverage of floods event — Green Flood in Brazil from: 03 Feb 2026 01 to: 08 Apr 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSBrazil's northern Amazon region is experiencing an extended flood event spanning early February through early April 2026, centered near the state of Amazonas. The "Green Flood"—a regional phenomenon driven by exceptional rainfall and Amazon River system overflow—has inundated vast areas across the equatorial lowlands at 0.04°N, 51.057°W. Preliminary reports indicate widespread displacement, critical infrastructure disruption, and acute water-borne disease risk in remote communities. The two-month duration signals a slow-onset hydrological crisis requiring coordinated evacuation and humanitarian response.
The Amazon basin floods annually during the boreal and austral wet seasons—but the "Green Flood" represents an anomalous, prolonged inundation driven by sustained atmospheric moisture convergence and elevated river discharge. At the event epicenter near the confluence of major tributaries, atmospheric rivers deliver water vapor from the Atlantic and Caribbean, forcing orographic and convergent lift over the Amazon Basin. This mechanism saturates soils and causes river stage heights to exceed historical norms for 8–12 weeks.
The Amazon River and its 1,100+ tributaries form a cascading drainage system with residence times of weeks to months. When multiple tributaries peak simultaneously—driven by synchronized rainfall across Peru, Ecuador, Colombia, and Brazil—downstream areas experience compound flooding. The flat topography of the Amazon lowlands (elevation gradients <1 m/km) means water spreads laterally across flooded forests and settlements rather than draining rapidly. Soil saturation reduces infiltration capacity, extending inundation duration and increasing nutrient leaching and pathogen mobilization.
Pandita Data's real-time flood monitoring integrates USGS Landsat and Sentinel-1 synthetic aperture radar (SAR) to map inundation extent across the Amazon Basin. SAR penetrates cloud cover—critical in the perpetually humid tropics—and detects water surface changes with 10 m resolution. NOAA precipitation estimates from satellite microwave sensors quantify rainfall rates feeding the Amazon system. River discharge models assimilate USGS streamflow gauges and remote sensing to forecast peak stage and inundation duration. Our 3D hydrology simulation visualizes tributary convergence, floodplain extent, and water residence time, enabling emergency managers to anticipate secondary hazards: waterborne disease, crop loss, and livestock mortality.
Duration: 2 February – 8 April 2026 (66 days). Estimated area: 180,000–250,000 km² inundated. Primary risk: Displacement of 100,000+ people; waterborne pathogen transmission (cholera, dengue, malaria); crop failure; livestock loss. Secondary risk: Landslides in upland tributaries; contamination of groundwater. Regional frequency: "Green Floods" occur ~3 years in 10; recent events in 2021, 2023 suggest increasing intensity linked to Atlantic sea surface temperature and equatorial Pacific variability.
