The national weather agency on Monday issued special warnings for heat waves in most parts of Korea, following heavy monsoon rains that caused casualties.
The hot and humid southwestern winds joined the North Pacific High, a semipermanent, subtropical anticyclone, around the edges overnight, causing temperatures to rise to tropical levels across Korea, except in some inland areas.
The lowest night temperatures marked as of 7 a.m. were 26.1 degrees Celsius in Seoul; 25.7 C in Suwon, Gyeonggi Province; 28.3 C in Gangneung, Gangwon Province; 26 C in Cheongju, North Chungcheong Province; 25.9 C in Yeosu, South Jeolla Province; 25.4 C in Gwangju; 26.8 C in Busan; 25.3 C in Daegu and 27 C for Jeju Island, according to the Korea Meteorological Agency.
When temperatures remain above 25 degrees from 6 p.m. through 9 a.m. the next day, the phenomenon is referred to as a tropical night here. Special warnings for scorching heat waves have been issued in most regions, including Daejeon, Gwangju, Busan, Daegu, Gangwon Province, the North and South Chungcheong, Jeolla and Gyeongsang provinces and Jeju Island.
