As the rain clouds that had dumped water bombs on the capital area and the Chungcheong region on the morning of the 17th quickly retreated to the northeast, all heavy rain alerts in these areas were lifted. Rainfall in the capital area was initially expected to top 100 millimeters in some places, but it has been revised down to a maximum of 20 millimeters. Currently, only parts of Gangwon are under a heavy rain advisory.
The Korea meteorological Administration said at 1 p.m. that it would issue a heavy rain advisory for Sokcho lowlands, Goseong lowlands, Yangyang lowlands, Hongcheon lowlands, Inje lowlands, and the northern mountainous area of Gangwon. The Korea meteorological Administration said, "Until this afternoon, centered on Gangwon and eastern North Jeolla, some areas will see very heavy rain of around 30 millimeters per hour accompanied by gusts and thunder and lightning."
Earlier in the day, all heavy rain advisories for Seoul, Gyeonggi, Incheon and South Chungcheong were lifted. The Korea meteorological Administration said, "In the capital area and South Chungcheong, less than 5 millimeters of rain per hour is falling or conditions are in a lull," adding, "As the rain cloud band accompanying a low pressure system that developed strongly over the West Sea moved east-northeast across the central region, the rain over the capital area and South Chungcheong weakened."
Accordingly, the Korea meteorological Administration also revised the expected rainfall downward. ▲Seoul, Incheon, Gyeonggi: 5–20 millimeters ▲Southeastern inland South Chungcheong, southern North Chungcheong: 10–40 millimeters ▲Daejeon, Sejong, South Chungcheong (excluding southeastern inland), central and northern North Chungcheong: 5–20 millimeters.
Most of the rain will stop tonight. However, Gyeongsang, Gangwon Yeongdong and Jeju Island will see rain continue through the 18th. In the Gangwon Yeongdong region, which includes Gangneung that suffered from "extreme drought," 10–60 millimeters of rain will fall on the 17th–18th, and there is also rain in the forecast for the 20th.
Meanwhile, in addition to the heavy rain advisory, strong wind, high seas and heat advisories are in effect simultaneously. Strong wind advisories were issued for Boryeong and Seocheon in South Chungcheong, and Gochang, Buan, Gunsan, Gimje and Jeongeup in North Jeolla, while a high seas advisory was issued for the outer central West Sea. Heat advisories are in effect for South Jeolla, North Gyeongsang, South Gyeongsang, Jeju, Daegu, Busan and Ulsan.
