Central Ohio flooding (19–30 May 2026) driven by saturated soils and intense precipitation causing Green River stage to exceed 18 feet; evacuation warnings active for multiple counties.
🌊 OPEN LIVE 3D WEATHER ALERTSA major flood event is affecting the central United States, with the Green River system in Ohio experiencing significant overflow from 19–30 May 2026. The flooding, centered near Columbus, Ohio (40.448°N, 82.775°W), poses immediate risks to riverside communities, infrastructure, and water quality across the region. Heavy precipitation combined with saturated soil conditions has driven river levels to near-record heights, prompting evacuation warnings and emergency response activations across Franklin and surrounding counties.
Flooding in the Ohio River basin results from the convergence of intense precipitation events and antecedent soil moisture. When rainfall exceeds infiltration capacity—particularly over clay-rich glacial soils common to central Ohio—runoff concentrates rapidly into tributary systems like the Green River, overwhelming channel capacity and inundating adjacent floodplains.
Pandita Data's hydrological monitoring integrates NOAA river gauges, USGS streamflow observations, and satellite precipitation data to track real-time flood extent and peak discharge. These live feeds reveal water surface elevation, inundation footprint, and return-period classification—enabling emergency managers to predict wave propagation and evacuation timing across downstream communities.
Riverine flooding accounts for $20+ billion in annual damage across the US. Central Ohio experiences 1-in-10-year floods approximately every decade due to glacial soil properties and urban impervious surfaces. Flood warning lead time averages 12–36 hours on major rivers like the Green.
