[Tomorrow's Weather] Thunderstorms with Lightning and Showers Amid Continued Heat and Tropical Nights

Thunderstorms and Heavy Rainfall Concentrated in Some Areas... Avoid Approaching Valleys and Rivers

As the longest consecutive tropical nights on record continue in Seoul and other regions, thunderstorms accompanied by lightning and showers are expected in some areas late afternoon on the 18th and on the 19th.

During the showers, temperatures will temporarily drop, but after the showers stop, temperatures are forecast to rise again during the day under high humidity, making it hot and humid.

Until the night of the 18th, showers are expected in the metropolitan area, inland and mountainous areas of Gangwon, the Chungcheong region, the Jeolla region, and Jeju Island, depending on the area. In Chungnam and Jeonbuk, these showers may continue until the early morning of the 19th.

On the 19th, the sky will be partly cloudy nationwide, with showers expected from the afternoon to nighttime in inland and mountainous areas of Gangwon, Chungnam, the Jeolla region, the Gyeongsang region, and Jeju Island.

Rainfall amounts due to showers on the 18th are expected to be 5 to 60 mm in Seoul, Incheon, Gyeonggi, and inland and mountainous areas of Gangwon; 5 to 40 mm in Daejeon, Sejong, Chungnam, Chungbuk, Gwangju, Jeonnam, and Jeonbuk; and 5 to 20 mm in Jeju Island.

On the 19th, rainfall amounts from showers are expected to be 5 to 30 mm in the West Sea Five Islands and inland and mountainous areas of Gangwon and Chungnam; and 5 to 40 mm in Gwangju, Jeonnam, Jeonbuk, Daegu, Gyeongbuk, Busan, Ulsan, Gyeongnam, and Jeju.

In some areas, thunder and lightning will occur, and very heavy rain exceeding 30 mm per hour may fall, so it is advised to avoid approaching valleys and rivers and to be cautious of safety accidents.

Even if showers occur, it is forecast to become hot and humid again as temperatures rise under high humidity after the rain stops. The lowest temperatures nationwide on the 19th will range from 22 to 27 degrees Celsius, and the highest temperatures will range from 32 to 36 degrees Celsius, which is slightly higher than the average (lowest 20 to 24 degrees, highest 27 to 31 degrees).

The tropical night phenomenon, where the lowest temperature remains above 25 degrees Celsius overnight, will continue. In the Seoul area, the tropical night has appeared for 28 consecutive days until the morning of that day, breaking the longest consecutive tropical night record since weather observations began, and it is highly likely to break this record again.

The Korea Meteorological Administration urged special caution regarding the possibility of heat-related illnesses, as the maximum apparent temperature will rise to around 35 degrees Celsius in most areas nationwide where heatwave warnings are currently in effect, making it extremely hot.
