According to the Korea Meteorological Administration on the 7th, rain will begin in the eastern coast and mountainous areas of Gangwon Province from early morning. Rain is also expected in the eastern coast and northeastern mountainous areas of North Gyeongsang Province starting in the morning, and in the mountainous and mid-mountain regions of Jeju Island from the late morning.

In particular, the eastern coast and mountainous areas of Gangwon Province, as well as the northern eastern coast and northeastern mountainous areas of North Gyeongsang Province, are expected to experience heavy and intense rainfall. Some areas may see a large amount of rain fall in a short period of time, so precautions should be taken against landslides and flooding.

From the afternoon into the night, showers are forecast to occur sporadically in the Seoul metropolitan area, inland areas of Gangwon Province, the Chungcheong region, Jeolla region, and inland areas of Gyeongsang Province.

The expected rainfall is 50–100 mm for the eastern coast and mountainous areas of Gangwon Province, with some locations possibly receiving more than 150 mm. The northern eastern coast and northeastern mountainous areas of North Gyeongsang Province are forecast to receive 30–80 mm, with amounts possibly exceeding 100 mm in certain areas. The southern eastern coast of North Gyeongsang Province is expected to receive 20–60 mm of rain.

In areas affected by showers, expected rainfall is around 5–40 mm in Seoul, Incheon, Gyeonggi Province, inland Gangwon Province, Daejeon, Sejong, South Chungcheong Province, North Chungcheong Province, North Jeolla Province, inland areas of Gwangju and South Jeolla Province, inland areas of Daegu and North Gyeongsang Province, and northwestern inland areas of South Gyeongsang Province.

While the rain is falling, the heat is expected to subside temporarily, but once the rain stops, increased humidity will likely cause the apparent temperature to rise, bringing back the intense heat.

The morning low is forecast to range from 22 to 27 degrees Celsius, and the daytime high is expected to be between 26 and 37 degrees Celsius. The heatwave is likely to continue in many areas, with daytime temperatures reaching around 35 degrees Celsius nationwide.
