Real-time coverage of floods event — Green Flood in Cambodia from: 28 Aug 2026 01 to: 02 Sep 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSA major flood event is sweeping the Mekong River plains near Kampong Chhnang Province, Cambodia, from August 28 to September 2, 2026. Heavy monsoon rains have saturated the region, triggering widespread inundation across low-lying agricultural land and riverside settlements centered near coordinates 13.09°N, 103.198°E. Water levels are expected to peak during this five-day window, affecting tens of thousands of residents and displacing vulnerable communities dependent on subsistence farming and water-based livelihoods.
Immediate risks include crop destruction, waterborne disease spread, and isolation of remote villages cut off from supply routes. The Mekong's natural flood pulse—essential for nutrient deposition—has intensified due to upstream dam releases and sustained monsoon precipitation. Authorities have issued displacement warnings for low-lying wards; evacuation centers are being activated across Kampong Chhnang and neighboring districts.
Cambodia's monsoon flood season (May–October) occurs when the Southwest Monsoon drives moisture-laden air from the Indian Ocean over Southeast Asia. The Mekong River's floodplain—a vast alluvial depression spanning 50,000 km²—naturally expands each year; water spreads across tributaries, wetlands, and agricultural fields. This August event is intensified by prolonged rainfall (200–300 mm over 10 days) combined with upstream dam operations in Laos and Thailand, which regulate water release and can amplify downstream surge.
The Great Lake (Tonlé Sap) acts as a natural buffer, expanding from 2,500 km² in dry season to 16,000 km² during peak flood. However, rapid inundation overwhelming drainage channels creates flash-flood conditions in populated areas, stranding populations and contaminating freshwater supplies with sediment and sewage.
Pandita Data integrates real-time NOAA precipitation radar, USGS water-level sensors, and satellite soil-moisture data to map inundation extent across the Mekong basin. Live 3D simulations overlay rainfall forecasts, river discharge rates, and topographic flow models, enabling communities and aid agencies to predict water arrival times and peak-stage timing. Flood extent maps update every 6 hours as satellite synthetic-aperture radar penetrates cloud cover over Southeast Asia.
The Mekong Delta floods seasonally; 80% of Cambodia's agricultural production depends on these floods for nutrient replenishment. However, rapid onset and dam-regulated surges amplify risk to urban areas. Average annual flood season affects 2–3 million Cambodians; mortality is low due to early-warning systems but displacement and food insecurity remain severe.
Monitor Pandita Data's live Mekong flood simulation for real-time inundation mapping and peak-stage forecasts—critical for evacuation timing and supply-chain planning across the region.
