Real-time coverage of floods event — Green Flood in India from: 23 Jun 2026 01 to: 25 Aug 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSA major monsoon flood event is affecting northeastern India from June 23 through August 25, 2026, centered on the Sylhet region (23.831°N, 91.282°E) with severe displacement and water-borne disease risk.
The Green Flood—a seasonal but intensifying hazard in the Indo-Gangetic Plain and Brahmaputra Valley—poses immediate threats to over 2 million people across Assam, Meghalaya, and Manipur. Communities in low-lying areas face rapid river overflow, landslides on saturated slopes, and contamination of drinking water supplies. Historical monsoon floods in this region (2004, 2016) displaced hundreds of thousands and destroyed critical infrastructure; this 2026 event's two-month duration signals prolonged humanitarian risk.
The Green Flood is driven by the Southwest Monsoon (June–September), which delivers 80% of annual rainfall to northeastern India. Orographic lifting—moisture-laden air forced upward by the Eastern Himalayas and Khasi Hills—generates extreme precipitation: Cherrapunji, Meghalaya receives over 11,000 mm annually, making it one of Earth's wettest locations. Combined with poor drainage in floodplains and upstream dam releases, saturated soils trigger both riverine and flash floods.
The Brahmaputra and Barak river systems, fed by Himalayan snowmelt and monsoonal rain, swell rapidly when groundwater tables reach surface level. Climate-change intensification has extended flood seasons and increased peak discharge by 15–20% over the past two decades.
Real-time satellite rainfall estimates (NOAA IMERG) and river discharge models (USGS) feed Pandita's 3D flood simulation, showing water extent, inundation depth, and flow velocity across floodplains in 6-hour updates. SRTM elevation data and OpenStreetMap settlement layers quantify population exposure and critical infrastructure at risk.
Annual Cost: $2–5 billion USD in damages and lost agricultural productivity. Seasonal Pattern: June–September peak; 2026 event spans full onset phase. Health Hazard: Cholera, dysentery outbreaks follow flooding due to contaminated water and sanitation collapse. Vulnerability: Rural populations, subsistence farmers, and informal settlements lack evacuation resources.
