Real-time coverage of floods event — Green Flood in United States from: 19 May 2026 01 to: 12 Jul 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSA prolonged flood event centered near the Missouri–Mississippi river junction affected the central United States from May 19 to July 12, 2026. The "Green Flood"—named for the river system at its epicenter—inundated communities across Missouri, Illinois, and adjacent states over 54 days, creating one of the longest-duration hydrological emergencies in the region's recent history. Peak inundation occurred during late May and early June, with water levels remaining critically elevated throughout the summer period.
This extended flood threatened agricultural zones, displaced thousands of residents, and stressed water infrastructure across the Mississippi River Basin. Communities within 50 kilometers of the epicenter (37.808°N, 91.185°W) faced the greatest risk of structural damage and crop loss.
Prolonged flooding in the Mississippi River system results from sustained rainfall, snowmelt, or upstream dam releases that overwhelm channel capacity. The Green Flood appears driven by anomalous precipitation patterns during spring 2026, likely amplified by atmospheric blocking—a condition where high-pressure systems trap moisture-laden air masses over a region for weeks. The Mississippi Basin's gentle gradient and extensive floodplain mean water recedes slowly once banks are breached.
Real-time satellite imagery (Sentinel-2, Landsat) detects surface water extent and changes in reflectance; NOAA river gauges measure discharge and stage height at dozens of stations. GDACS (Global Disaster Alert Coordination System) integrates these data streams to issue flood advisories. Pandita Data's 3D hydrology simulations display water surface elevation, flow vectors, and inundation footprints updated daily during active events.
Return period: Floods of this duration occur approximately every 25–50 years in this region. Vulnerability: ~2.3 million people live within 10 km of the main channel. Economic sector: Agricultural losses typically exceed $500 million per 7-day flood event.
