Rain is expected nationwide from the 9th through the morning of the 10th, with somewhat chilly weather continuing.
The Korea Meteorological Administration said on the 8th, "On the 9th–10th, strong, heavy rain accompanied by gusts and thunder and lightning will fall, focusing on Jeju Island and the south coast."
This round of rain will concentrate in the southern regions. Mountain areas of Jeju Island are expected to receive more than 250 millimeters, and the south coast more than 120 millimeters of heavy rain. In particular, Jeju Island and the Jeolla coast will see heavy rain of 30–50 millimeters and 20–30 millimeters per hour, respectively, during the day on the 9th, and the Gyeongnam coast will continue to see heavy rain of 20–30 millimeters per hour in the evening.
With strong winds blowing, concerns are high about damage to facilities and safety accidents. The Korea Meteorological Administration said, "Winds will be strong, focusing on Jeju Island, the west coast, and the south coast, and there is a possibility of disruptions to flight operations."
The rain will gradually stop from the morning of the 10th, but it appears rain will continue through the daytime, focusing on the central regions.
Afterward, on the weekend of the 11th–12th, the country will be mostly clear under the influence of a mobile high-pressure system. From the afternoon of the 12th, it may rain again in Jeju Island and the southern regions, but next week is expected to see mostly clear weather.
Temperatures will recover quickly starting this weekend. Morning lows will be around 10 C, the seasonal average, and daytime highs will be 22–24 C, warmer than average. However, the temperature difference between day and night will widen to more than 15 C in inland areas, so take care of your health.
