South Korea extreme weather: flood warning after dam release

Overview

The Korea Meteorological Administration continues to monitor a high‑pressure‑driven heatwave that has kept daytime temperatures near 37 °C nationwide, with perceived temperatures of 38 °C–39 °C in Gyeongsan and Pohang. The emergency heat‑wave warning remains in force and disaster‑safety headquarters stay at the highest emergency level. Health authorities have recorded a rapid rise in heat‑related illnesses, with 636 cases treated and two deaths reported. Since mid‑July, intense rainstorms that began on 17 July have swept central South Korea. By 20 July, 557 residents from 374 households across six provinces were displaced, 119 remained unable to return home and 83 were housed in temporary shelters. Floods damaged 41.6 ha of crops and 7.1 ha of farmland, generated 256 reports of inundated homes and roads, and triggered 572 landslide or rock‑fall incidents. No fatalities have been confirmed. Authorities have kept the disaster alert at “caution,” activated a secondary response team, and are inspecting over 150,000 structures for flood risk. Additional rainfall of 30‑80 mm was forecast for the night of 20 July, with river levels closely monitored. On 21 July, South Korean officials responded to an unannounced release of water from North Korea’s Hwanggang Dam, which pushed the Imjin River’s Pilseunggyo gauge in Gyeonggi Province to nearly 9 m, well above the 1 m evacuation threshold. Flood‑control measures were activated, evacuation directives issued for low‑lying areas, and fire‑brigade and police units mobilised. The Korean Meteorological Administration warned of up to 60 mm of additional rain in central regions and temperatures reaching 37 °C, heightening the risk of overflow and infrastructure strain. A similar surge occurred on 21 July 2026 when South Korean authorities issued a flood advisory for the Imjin River in Yeoncheon County after heavy downpours and satellite imagery confirmed another unannounced release from the Hwanggang Dam.
