In particular, heavy rain is forecast for the central regions—including the Seoul metropolitan area, Gangwon-do, and Chungcheong—at a rate of 20 to 80 millimeters per hour from early morning to late morning.

The predicted rainfall over the two days of the 20th and 21st is as follows: 30 to 100 millimeters for Seoul, Incheon, Gyeonggi, and the five islands of the West Sea (with more than 150 millimeters expected in parts of northern Incheon and northern Gyeonggi); 30 to 100 millimeters for the inland and mountainous areas of Gangwon (with over 150 millimeters in northern Gangwon inland); and 10 to 60 millimeters along the east coast of Gangwon.

Daejeon, Sejong, Chungnam, and Chungbuk are expected to receive 30 to 80 millimeters of rain (with over 100 millimeters likely along the northern coast of Chungnam), while Gwangju and Jeonnam will see 5 to 40 millimeters, Jeonbuk 10 to 60 millimeters, Daegu and Gyeongbuk 10 to 60 millimeters, western inland areas of Gyeongnam 5 to 40 millimeters, and Jeju 5 millimeters.

Owing to the heavy concentration of rain in the central regions, there is a possibility that heavy rain warnings will be issued, as the rainfall may be accompanied by strong winds, thunder, and lightning.

Oppressive heat will continue. With heat wave advisories in effect for parts of the Chungcheong and southern regions as well as Jeju, the apparent maximum temperature across most areas nationwide is expected to exceed 31 degrees Celsius.

In particular, in areas under heat wave advisories, the apparent maximum temperature is projected to be around 33 degrees Celsius, and approximately 35 degrees Celsius in Jeonnam, Gyeongsang, and Jeju, so caution is advised against heat-related illnesses.

Morning lows are forecast to range from 22 to 26 degrees Celsius, with daytime highs expected to range from 26 to 37 degrees Celsius.

Waves on the sea will be 0.5 to 1.5 meters high on the East and South Sea coasts, and 0.5 to 1.0 meters on the West Sea coast.

In the offshore areas within about 200 kilometers from the coastline, waves in the East Sea, West Sea, and South Sea are expected to reach 0.5 to 1.5 meters.
