Tomorrow 'Daeseo' Heatwave in Gangwon, Chungcheong, and Jeju... Rainy Season Showers Across the Country

Impact of the Stagnation Front... Gusts, Thunder, and Lightning Also

On Monday the 22nd, which is Daeseo (大暑), known as the hottest day of the year, hot weather is expected mainly in some areas of Gangwon, Chungcheong, and Jeju. The entire country will be cloudy with intermittent monsoon rain in various places.

According to the Korea Meteorological Administration on the 21st, on the 22nd, under the influence of a stationary front, the whole country will be mostly cloudy, with heavy rain in some areas, especially around the Seoul metropolitan area and inland and mountainous regions of Gangwon.

There will be occasional rain in the central region excluding the east coast of Gangwon, and in the northern inland areas of North Gyeongsang Province. Jeju Island will have occasional cloudy skies.

Expected rainfall (from the 21st to the 22nd) is 20-60 mm (over 80 mm in some areas) for the Seoul metropolitan area and the five western islands, 10-50 mm for Gangwon Province, 5-40 mm (over 60 mm in the northern coastal area of Chungnam) for the Chungcheong region. Additionally, 5-40 mm in Jeonbuk, 5-20 mm in Gwangju and Jeonnam, 5-40 mm in the Gyeongsang region, 5-20 mm in Daegu, southern Gyeongbuk, and inland Gyeongnam, and around 5 mm in Jeju.

In particular, the Seoul metropolitan area may experience very heavy rain from morning to night on the 22nd, so special caution is required. With heavy rain expected in North Korea from the 22nd to the 23rd, water levels in northern Gyeonggi Province may rise rapidly, so residents nearby should be especially careful. Rising river water levels and flooding and overflow in downstream river areas due to dam water gate openings, as well as strong currents, should be watched closely.

Additionally, preparations should be made for facility management and safety accidents caused by gusts of wind along with thunder and lightning. On the central west coast and Gangwon Yeongdong, winds may blow strongly with instantaneous speeds exceeding 55 km/h in some areas.

There will also be sea fog in some maritime areas, and dense fog with visibility less than 200 meters may occur in some island regions.

The lowest morning temperature on the 22nd will be between 23 and 27 degrees Celsius, and the highest daytime temperature will be between 28 and 34 degrees Celsius, slightly higher than the average (morning low 21-24 degrees, daytime high 28-32 degrees). The highest perceived temperature will rise above 33 degrees Celsius mainly in Gangwon, Chungcheong, southern regions, and Jeju, making it very hot.

The highest temperatures by city are Seoul 29°C, Incheon 28°C, Chuncheon 29°C, Gangneung 32°C, Daejeon 32°C, Jeonju 33°C, Gwangju 32°C, Jeju 34°C, Daegu 34°C, and Busan 30°C.
