A 10-day flooding event struck Colombia's Bogotá region (17–27 Apr 2026), driven by orographic precipitation and river overflow, threatening thousands with inundation and displacement.
🌊 OPEN LIVE 3D WEATHER ALERTSA major flooding event designated the "Green Flood" struck the Bogotá region of Colombia beginning 17 April 2026, with critical water levels and overflow conditions persisting through 27 April. The event, centered near coordinates 5.492°N, 73.485°W in the Andean foothills, has triggered widespread inundation across agricultural and residential zones in the high-altitude plateau region. Authorities have classified this as a severe hydrological emergency with displacement risks affecting thousands of residents downstream from swollen tributaries feeding the Río Bogotá system.
This flooding event results from a convergence of orographic precipitation and seasonal runoff intensification in Colombia's Eastern Cordillera. Moisture-laden air masses from the Caribbean and Pacific collide with the 2,600-meter elevation barrier of the Andes, forcing rapid condensation and sustained heavy rainfall—a classic orographic lift mechanism. The timing coincides with Colombia's rainy season transition, when antecedent soil moisture is already near saturation, preventing infiltration and forcing precipitation directly into overland flow and stream channels.
Pandita Data's real-time precipitation and streamflow simulations integrate NOAA rainfall radar, USGS discharge gauges, and NASA satellite imagery to map flood extent and persistence. Live 3D hydrological models show water height evolution across the Bogotá basin, enabling rapid identification of critical overflow zones and community risk corridors during the 10-day event window.
Seasonal Risk: April–May flooding is Colombia's primary spring flood season. Vulnerability: Bogotá plateau communities lack modern levee systems; informal settlements occupy historic floodplain margins. Duration Hazard: Multi-day floods cause cumulative property damage and disease vectors in standing water.
