Heavy rain is expected to pour down in the metropolitan area and inland regions of Gangwon Province overnight from July 9 to July 10.
According to Yonhap News, heavy rain warnings have been issued for Seoul, southern Gyeonggi Province, inland and mountainous areas of central and southern Gangwon, Chungcheong, Honam, and northern and central North Gyeongsang Province. Southern Gyeonggi Province is experiencing rainfall exceeding 50 mm per hour, while other areas in central Korea and the western coast of Jeolla and northern Gyeongsang are seeing rain of 20 to 40 mm per hour.
Throughout the day, very heavy rain of 20 to 80 mm per hour is expected in central regions, as well as the western coasts of North and South Jeolla and northern and central North Gyeongsang.
As the day progresses, a stationary front is expected to gradually move northward in line with the expansion of the North Pacific high-pressure system, leading to a decrease in rainfall in Chungcheong and southern regions starting from the evening. However, rain will continue in the metropolitan area and Gangwon Province until the morning of July 10.
The forecasted rainfall amounts are as follows: 50 to 100 mm in inland and mountainous areas of Gangwon (with some places exceeding 150 mm), 30 to 80 mm in the metropolitan area, Chungcheong, western North Jeolla, and central western South Jeolla (with some areas in the metropolitan area, Chungcheong, and western North Jeolla exceeding 120 mm, and some areas in northern and central western South Jeolla exceeding 100 mm), 30 to 80 mm in central and northern North Gyeongsang, 20 to 60 mm in the five western islands, 5 to 50 mm on the eastern coast of Gangwon, and 10 to 40 mm in Gwangju, South Jeolla (excluding northwestern and central western coasts), Daegu, southeastern North Gyeongsang, western inland areas of South Gyeongsang, Ulleungdo, and Dokdo, with 5 to 40 mm expected in mountainous areas of Jeju and less than 5 mm in Jeju (excluding mountainous areas).
After the rain subsides, a heat wave is expected to take hold. Currently, heat wave warnings have been issued primarily in the Yeongnam region, and by July 11, these warnings are expected to expand to central regions and later to most areas nationwide.
However, another round of rain is anticipated around July 15 to 16 as cold air moves down from the north.
