According to the Korea Meteorological Administration, as of 6 a.m. on this day, the cumulative precipitation over the past 12 hours since 6 p.m. the previous day was significant nationwide: 137.5 mm at Samgakbong on Hallasan Mountain in Jeju, 94.0 mm in Sangju (Euncheok), North Gyeongsang Province, 64.5 mm in Boseong, South Jeolla Province, 88.0 mm in Gongju (Jeongan), South Chungcheong Province, 81.0 mm in Samcheok (Munijae), Gangwon Province, 60.6 mm in Seoul, and 40.5 mm in Incheon, among other locations.

In particular, the central region and the mid-to-northern parts of North Gyeongsang Province may see rain continue until late at night, while mountainous areas of Gangwon Province and the east coast are expected to experience precipitation through the morning of the 21st. The additional expected rainfall is as follows: 50–120 mm in mountainous and coastal areas of Gangwon (with up to 200 mm or more in the northern mountains and up to 150 mm or more in central mountains and the mid-northern east coast), 30–80 mm in the Seoul metropolitan area, inland Gangwon, Daegu, North Gyeongsang Province, Ulleungdo, and Dokdo, 20–60 mm in Chungcheong, North Jeolla, Busan, Ulsan, and South Gyeongsang Province (with up to 80 mm or more near Jirisan), and 5–40 mm in the five West Sea islands, Gwangju, South Jeolla, and Jeju (with up to 80 mm or more in central and mountainous parts of Jeju).

Heavy downpours with hourly rainfall rates of 30–50 mm in northern mountainous Gangwon and 20–30 mm in Yeongnam are expected at times through the morning. In mountainous areas and the east coast of Gangwon, heavy rain at hourly rates of 20–30 mm is forecast to resume from the morning (afternoon in the northern mountains) through the night.

On the Jeolla coast, South Gyeongsang coast, and most of Jeju (excluding the north), strong winds with instantaneous speeds of 70 km/h (90 km/h in mountainous areas) are expected through the afternoon. From the afternoon, the east coast of Gangwon will also see these strong winds. Other regions will experience gusts of at least 55 km/h (70 km/h in mountainous areas), so caution is advised against heavy rain and strong winds.

At sea, strong winds of 30–65 km/h (9–16 m/s) and waves of 1.5–4.0 meters are forecast until the afternoon in the southern outer West Sea, inner offshore waters of Jeju, and the nearshore waters off Jeju (excluding the northern nearshore). The eastern part of the southern offshore West Sea will experience these conditions through the night, while the southern outer offshore waters of Jeju and the outer eastern South Sea are expected to have rough seas with these conditions until dawn on the 21st.

Temperatures will be similar to or slightly lower than average. At 8 a.m., the temperatures in major cities were: Seoul 20.6°C, Incheon 21.9°C, Daejeon 21.9°C, Gwangju 23.8°C, Daegu 23.5°C, Ulsan 23.5°C, and Busan 22.7°C. The daytime high is expected to range between 22°C and 30°C.
