Rainfall is forecast across South Korea throughout Saturday, the day before the summer solstice. Eastern Gangwon province is expected to receive the heaviest rainfall, with accumulations of 50 to 120 millimeters. The Seoul metropolitan area will likely see between 30 and 80 millimeters of rain. While precipitation will continue until evening, conditions are expected to ease off during the afternoon. Authorities have not issued specific warnings, but residents are advised to prepare for potential localized flooding or disruptions. The rainfall is attributed to a seasonal weather system bringing moisture to the Korean peninsula. This precipitation follows a period of relatively dry weather in many regions.
