[Asia Economy Reporter Han Jinju] On Chuseok day, the 21st, heavy rain will fall nationwide, and rain will stop in the Seoul metropolitan area, Chungnam, and Jeolla regions from the afternoon. The full moon will appear between 6:50 PM and 7:00 PM, but due to cloudy weather, it is expected to be difficult to observe in many areas.

As of 10 AM, due to the influence of a low-pressure trough, strong rain accompanied by thunder and lightning with about 30mm per hour is falling in the Gyeongsang region, while other areas are experiencing rain of about 5mm per hour. By this afternoon, the Jeonnam region, Gyeongnam region, southern Jeju, and mountainous areas will receive over 100mm, southern regions and Jeju 20-70mm, central regions 10-50mm, and Gangwon Yeongdong and the eastern coast of Gyeongbuk about 5-20mm of rain.

Until 6 PM, when the low-pressure trough moves out to the East Sea, heavy rain and strong winds will continue, so caution is advised. In the Gyeongsang region, gusts with maximum wind speeds exceeding 15 m/s and heavy rain over 30mm per hour will occur. In Gangwon Yeongseo, Chungbuk, and eastern Jeonbuk, rain of about 5-10mm per hour is expected in some areas. Other regions, including Seoul, will experience sporadic rain until the afternoon.

The Korea Meteorological Administration stated, "During the heavy rain today and tomorrow, there will be many places with gusts and frequent thunder and lightning, so special caution is needed for safety accidents caused by gusts and lightning during outdoor activities such as visiting ancestral graves and hiking, as well as for the management of various facilities." They added, "From tonight to tomorrow daytime, some areas may experience hail, so special attention is required to prevent damage to crops during the harvest season and safety accidents."

With rain falling nationwide, the chance of seeing the full moon is low due to cloudy weather. According to the Korea Astronomy and Space Science Institute, the moonrise times are ▲Seoul 18:59 ▲Incheon 19:00 ▲Suwon 18:59 ▲Gangneung 18:51 ▲Chuncheon 18:56 ▲Daejeon 18:57 ▲Cheongju 18:57 ▲Daegu 18:52 ▲Busan 18:50 ▲Ulsan 18:49 ▲Gwangju 18:59 ▲Jeonju 18:58 ▲Jeju 19:00.

From the night of the 21st, rain will resume in the Seoul metropolitan area and Gangwon Yeongseo. This is due to the inflow of cold air in the upper atmosphere and warm, humid air moving southward ahead of the low-pressure trough from the northwest, causing atmospheric instability. Rain will expand to Chungcheong region, Jeonbuk, northern Jeonnam by dawn on the 22nd, southern Jeonnam in the morning, and inland Gyeongbuk and northwestern inland Gyeongnam in the morning.

From dawn to morning on the 22nd, some areas in the Seoul metropolitan area and Chungcheong region and Jeonbuk will experience heavy rain of about 20-30mm per hour. During the day, as temperatures rise due to sunlight, localized convective cloud bands will develop, causing heavy rain of about 20-30mm per hour mainly in inland areas.

The expected rainfall from the night of the 21st to the 22nd is 10-60mm in the Seoul metropolitan area, Gangwon Yeongseo, and Chungcheong region. On the 22nd, Jeonbuk will receive 10-60mm, and Jeonnam, inland Gyeongbuk, and northwestern inland Gyeongnam 5-40mm.

Daytime temperatures will rise above 25 degrees Celsius in regions except the central area and will gradually drop below 25 degrees from the 22nd. Morning temperatures on the 22nd will be around 20 degrees in most areas. The inland Gyeongsang region will have a temperature difference of over 10 degrees between day and night, so health management is advised.
