Most of the rain will stop, but there will be places where rain continues until night, including the southern coast of Jeollanam-do, the Gyeongnam region, and Jeju. Especially in the southern regions and Jeju Island, there will be very heavy and intense rain accompanied by gusty winds, thunder, and lightning.

In the Jeonnam and Gyeongnam regions, rain will fall until daytime, and in Jeju, very heavy rain of 30 to 50 mm per hour is expected between morning and daytime. In Gangwon-do and southern Chungcheong provinces, rain will continue until morning, while in Jeonbuk until daytime, with hourly rainfall exceeding 20 mm, and in the Gyeongbuk region, about 30 mm per hour until daytime.

The expected rainfall for the day is forecasted as follows: Gwangju and Jeonnam, Busan, Ulsan, Gyeongnam, and Jeju 30 to 80 mm (with some areas exceeding 100 mm, Jeju over 120 mm), eastern Gyeonggi 5 to 30 mm, Seoul, Incheon, western Gyeonggi 5 to 10 mm, and the five islands in the West Sea about 5 mm.

The daytime high temperature is forecasted to be between 24 and 32 degrees Celsius. Many places, especially in northern Gyeonggi and the Gyeongbuk region, will see temperatures rise above 30 degrees Celsius. As the rain stops in the afternoon and humidity rises, the highest perceived temperature will reach around 31 degrees Celsius, mainly in inland areas nationwide.

Fine dust levels are expected to be 'Good' nationwide due to smooth atmospheric dispersion and the influence of precipitation.

Strong wind warnings have been issued mainly for the west coast, south coast, the east coast of Gyeongbuk, and Jeju Island, with wind gusts exceeding 70 km/h. Elsewhere nationwide, winds will also be strong with gusts exceeding 55 km/h (70 km/h in mountainous areas).

Winds will be very strong at most sea areas as well, blowing at speeds of 35 to 70 km/h, causing high waves. There will be places with gusty winds accompanied by thunder and lightning at most sea areas.

Wave heights will be 1.0 to 4.0 meters in the East Sea nearshore waters, and 1.0 to 3.5 meters in the West Sea and South Sea nearshore waters.

In the outer offshore waters (about 200 km from the coastline), wave heights are predicted to be 1.5 to 5.0 meters in the East Sea, 2.0 to 4.0 meters in the West Sea, and 1.5 to 4.0 meters in the South Sea.
