Real-time coverage of floods event — Green Flood in United States from: 19 May 2026 01 to: 22 Aug 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSA prolonged flood event affected the Columbus, Ohio area from May 19 through August 22, 2026, creating sustained inundation risks across central Ohio watersheds. The extended three-month duration indicates anomalous precipitation patterns or severe hydrological persistence in the region near coordinates 39.714°N, 82.208°W. Communities face compounded risks from saturated soils, damaged infrastructure, and potential secondary flooding from tributary systems.
Residents in affected zones experienced displacement, crop losses, and compromised water quality throughout the summer season. The prolonged nature of this event suggests either repeated precipitation events or incomplete drainage from earlier storms, both creating persistent hazards for agriculture, utilities, and populated areas downstream.
Extended flooding in Ohio results from the collision of moist air masses with regional topography and soil saturation. The Ohio River basin experiences seasonal precipitation, but three-month duration floods typically indicate either blockage of normal drainage channels or sustained atmospheric moisture delivery from the Gulf of Mexico or Atlantic systems.
Clayey soils common to central Ohio have low permeability, causing water to pond rather than infiltrate rapidly. When antecedent moisture is high—meaning soils are already wet from prior rain—additional precipitation cannot be absorbed, forcing overland flow into streams and rivers that quickly exceed bankfull capacity.
Real-time satellite precipitation radar from NOAA detects rainfall patterns feeding the flood. Soil moisture indices derived from Sentinel-1 synthetic aperture radar (SAR) reveal water saturation levels across the basin. Stream gauge data from USGS continuously monitors discharge rates and water height at key monitoring points.
Our 3D weather simulation overlays precipitation forecasts, soil conditions, and river network topology, helping visualize how water moves through the Ohio watershed over hours and days. This integration reveals why certain areas remain inundated while others drain.
Duration: 95 days (May 19 – Aug 22, 2026) | Region: Central Ohio (Columbus area) | Primary risk: Infrastructure damage, agricultural loss, contaminated water supplies | Secondary risk: Mosquito-borne disease, mold, electrical hazards in flooded structures.
