Monsoon rains are forecast to affect South Korea starting Wednesday, with the Korea Meteorological Administration (KMA) citing a stationary front forming and lingering over the Yellow Sea. The KMA expects heavy downpours to expand from central areas toward broader parts of the country, continuing into Thursday. Rainfall is expected to begin in parts of the country by Wednesday morning, with the broader Seoul area, including Gyeonggi and Incheon, along with inland areas of Gangwon, seeing 50 to 100 millimeters over the two-day period. Central regions are forecast to receive higher totals: Daejeon, South Chungcheong, and North Chungcheong are expected to get 80 to 150 millimeters, while some locations in those areas could exceed 200 millimeters. The southwestern part of North Jeolla and central and northern areas of North Gyeongsang are also included in the heavier-rain outlook. The KMA also warns that strong winds and thunderstorms may accompany the rain through Thursday. After rain eases in many areas late Thursday, the forecast period shifts toward a nationwide heat wave on Saturday under the influence of the North Pacific high-pressure system.
