From tomorrow night until the early morning of the day after tomorrow, strong rain is expected to pour mainly in the northern part of the capital region. The relatively cool weather has been felt for a while, but it will start to get hot around Liberation Day. A heat wave and tropical nights are expected to return.
The Korea meteorological Administration noted during a regular forecast briefing on the 12th that "until today, heavy rain is expected mainly in southern Chungcheong, southern regions, Jeju Island, and the southern coast," adding that "from the afternoon of the 13th to the morning of the 14th, strong rainfall is expected, particularly in the northern Gyeonggi region, including Seoul."
The stationary front producing the rain is currently forming over the southern sea and is expected to gradually move northward into the central region. There is a possibility of severe weather with heavy rain falling at a rate of 30 to 50 mm per hour starting from the afternoon of the 13th, when the stationary front remains over the capital region. However, due to the stationary front developing into a very narrow band shape from north to south, the precipitation amount could vary by 3 to 4 times depending on the region within the capital region.
The Korea meteorological Administration forecasted that more than 150 mm of heavy rain would be concentrated in the "northern Gyeonggi" region over the two days from the 13th to the 14th. Additionally, ▲ Seoul and southern Gyeonggi are expected to get 50 to 120 mm ▲ northern Chungnam and inland mountainous areas of Gangwon might see over 100 mm ▲ over 60 mm of rain is predicted for the southern coasts of South Jeolla and South Gyeongsang. Meanwhile, the eastern coast of Gangwon is expected to receive about 5 to 20 mm of precipitation, leading to relatively less rain in that region.
Starting from the 15th, which is Liberation Day, the heat is expected to return. The North Pacific high-pressure system, which has been retreating towards Japan, will once again cover Korea, and the Tibetan high pressure will overlap above it, strengthening the heat wave. The phenomenon of tropical nights, which had appeared in only a few areas recently, will also resurge nationwide. However, the Korea meteorological Administration forecasted that temperatures would not rise as much as they did during the extreme heat wave at the end of July.
Meanwhile, as of 12 p.m. that day, temperatures across the country are between 21 and 31 degrees Celsius. Heavy rain warnings are in effect in some areas, including Wando, Goheung, and Yeosu in South Jeolla, Tongyeong and Geoje in South Gyeongsang, and the mountainous regions of Jeju.
