As South Korea’s summer monsoon season reaches its peak, communities across the country are grappling with the relentless impact of heavy rains, flash floods, and landslides. From July 17 to July 20, 2026, a series of powerful downpours swept through both urban and rural regions, leaving a trail of flooded homes, damaged infrastructure, and disrupted lives. The country’s disaster response systems have been put to the test, with local governments, police, and volunteers working around the clock to protect vulnerable residents and restore normalcy.
According to the Central Disaster and Safety Countermeasures Headquarters (CDSCH), the rainfall totals over this period were staggering: Yeongju in North Gyeongsang Province recorded 209.9 millimeters, Paju in Gyeonggi Province saw 205.5 millimeters, and Dongducheon wasn’t far behind at 204.0 millimeters. Even the capital, Seoul, experienced significant rainfall, with Gangseo District measuring 186.0 millimeters and Goyang in Gyeonggi Province tallying 173.5 millimeters. These figures, reported by Shinailbo, underscore just how widespread and intense the deluge has been.
The consequences were immediate and severe. The CDSCH reported 254 cases of house and road flooding, 756 incidents involving landslides and rockfalls, and damage to temporary modular homes in fire-affected areas of North Gyeongsang Province. Farmland wasn’t spared either: 42.6 hectares of crops were inundated and 7.4 hectares of agricultural land were lost or buried, with peppers, apples, rice beans, sesame, and cucumbers among the casualties. Rescue crews were dispatched 34 times, and more than 560 people from 377 households in 21 cities and counties were temporarily evacuated for their safety.
In response to the escalating crisis, the CDSCH raised the disaster alert level to ‘Warning’ on July 18 and initiated Level 2 emergency operations. This move triggered a cascade of actions at the local level, particularly in hard-hit areas like Andong City. As reported by Sisa News, Andong activated its own emergency disaster safety headquarters on July 18 and quickly ramped up its response as rainfall intensified. By 3 p.m. on July 19, Namseon-myeon had received 201 millimeters, Imha-myeon 169 millimeters, Imdong-myeon 135.5 millimeters, and Namhu-myeon 130 millimeters. Despite early patrols, preemptive evacuations, and facility inspections, some neighborhoods still suffered house flooding and other damages.
Mayor Kwon Ki-chang of Andong visited affected areas to assess the situation firsthand, urging his staff and local agencies to ensure “swift emergency recovery and support for affected residents.” On July 19, 179 personnel—including volunteers, city employees, and members of the Red Cross—were deployed to help clean flooded homes and survey damage. The following day, nearly 200 more, including military personnel and civic groups, were mobilized to continue the recovery effort.
Meanwhile, in Seoul’s Seongdong District, authorities adopted a proactive approach to protect those most at risk. On July 20, the district announced the operation of a ‘Flood Vulnerable Household Care Team’—an 89-member group composed of local leaders, residents, and care officials focused on flood-prone households through October. According to the district’s announcement, the team is on high alert whenever rainfall forecasts exceed 20 millimeters in 15 minutes or 55 millimeters in an hour, triggering emergency communication and rapid deployment. Priority is given to 49 semi-basement households with elderly or disabled residents who may have difficulty evacuating on their own.
To ensure the team’s readiness, Seongdong District conducted specialized safety training on July 16, covering disaster preparedness, response systems, and evacuation support procedures. District Mayor Yoo Bo-hwa emphasized, “Preemptive preparation and rapid response are more important than anything else to protect residents’ lives and safety amid unpredictable concentrated heavy rain.” The district’s goal is clear: to build a community where “all residents can feel safe.”
The police have also played a pivotal role in the disaster response. On July 20, Kim Won-tae, Chief of the Gyeongbuk Provincial Police Agency, visited disaster-prone areas in Yecheon County and flood-damaged sites in Andong and Uiseong. As reported by Straight News, Chief Kim met with evacuees at a modular housing complex in Iljik-myeon, Andong, and received briefings on recovery operations. In Uiseong’s Gugye-ri, he inspected a damaged road for risks of further collapse and coordinated with agencies on traffic control and recovery progress. To prevent a lapse in public safety, the Gyeongbuk police have set up temporary police stations, deployed patrol teams, and installed mobile CCTVs in affected areas. They continue to support traffic management, evacuation, and missing person searches in partnership with other agencies.
“We will do our utmost to maintain security and help residents recover normal life,” Chief Kim declared, pledging ongoing preventive patrols and resident protection activities.
Yet, as the week progressed, the weather remained unpredictable. YTN’s meteorological coverage on July 20 reported that while the rain had temporarily weakened in the central region—including Seoul, where the Cheonggyecheon stream remained accessible—forecasters expected another round of heavy rain overnight. The northern and central regions were bracing for up to 50 millimeters per hour, with up to 150 millimeters possible in northern Gyeonggi and Gangwon Provinces by July 21. Even as some areas enjoyed a brief reprieve, others, particularly in the south, faced heatwave warnings and “tropical nights” with minimum temperatures above 25 degrees Celsius in cities like Daegu and Gwangju. Daytime highs were forecast to reach 28 degrees in Seoul, 34 in Daegu, and a scorching 35 in Gyeongju.
The shifting weather front promised more volatility, with alternating bouts of rain and heat impacting different regions throughout the week. “Already, many places have weakened ground due to previous heavy rain,” YTN’s weathercaster noted, urging residents to check their facilities and stay alert for further flooding or landslides.
With saturated soil, swollen rivers, and a forecast of more rain, officials and citizens alike are keenly aware that vigilance and cooperation remain essential. The past week’s events have underscored both the vulnerabilities and the resilience of South Korean communities in the face of nature’s unpredictable power. As the summer unfolds, the lessons learned—and the efforts underway—will be crucial in safeguarding lives and livelihoods against whatever the next storm may bring.
