64-day flooding event in West Java (March–May 2026) driven by monsoon rainfall saturation. Affects 8+ million residents; disease and crop loss risks escalate. Evacuate to high ground.
🌊 OPEN LIVE 3D WEATHER ALERTSA prolonged flooding event began on 2 March 2026 across West Java, Indonesia, centered near coordinates -7.01°S, 107.551°E (Bandung region). The flood sequence, extending through 5 May 2026, represents an unusually sustained hydrometeorological disaster affecting densely populated agricultural and urban zones. Initial reports indicate significant water accumulation across low-lying valleys and settlements, with risk of disease outbreak and crop loss intensifying as inundation persists over 64 days.
West Java's geography—a region of narrow river valleys draining toward the Indian Ocean—creates natural congestion points for monsoon runoff. The March–May period aligns with the tail end of the Southern Hemisphere wet season, when upper-level atmospheric moisture from the tropical Indian Ocean converges over Java's volcanic ridges. Orographic lifting forces air masses upward, cooling and releasing precipitation across slopes; sustained rainfall saturates soil and overwhelms river channels, forcing water into floodplains and residential areas for weeks.
Real-time satellite precipitation sensors (NOAA, NASA IMERG) detect rainfall rates across the Bandung watershed. Soil moisture indices track saturation thresholds; when antecedent moisture exceeds 80%, even moderate rain triggers overflow. Our 3D hydrology simulation integrates topography, soil permeability, and discharge rates, predicting flood extent and persistence across floodplains hour-by-hour.
West Java experiences 3–5 major flood episodes annually. The Ciliwung, Citarum, and Cisadane rivers are repeat offenders; urban expansion has reduced green space, accelerating runoff. Multi-day inundation increases waterborne disease (cholera, typhoid), malnutrition in displaced populations, and crop damage worth millions of USD.
