On August 4, a strong east wind is expected to bring extreme heat to the western regions of South Korea, including the metropolitan area.
According to Yonhap News, a high-pressure system in the lower atmosphere has moved north since the previous day, currently positioned over North Korea. This has resulted in an east wind blowing into South Korea, causing temperatures to rise due to a phenomenon known as foehn, where air heats up as it descends from mountains.
As a result, the eastern coastal areas of Gangwon and northern Gyeongsangbuk-do will experience relatively cooler temperatures due to the east wind.
Heat wave warnings have been issued and are in effect for regions including Boseong, Yeosu, Gwangyang, Suncheon, southern and northern Gokseong, eastern Gwangju, Osan, Hanam, western Yeoju, southeastern and southwestern Seoul, with temperatures expected to exceed 39 degrees Celsius or feel like 38 degrees Celsius.
The highest daytime temperatures nationwide are projected to range from 30 to 38 degrees Celsius.
Seoul and Gwangju are expected to reach 38 degrees, Incheon and Daejeon 37 degrees, Daegu 36 degrees, and Ulsan and Busan 34 degrees. Most other regions will also feel temperatures around 35 degrees.
Additionally, from afternoon to evening, light rain is forecasted, with 5 to 60 mm expected in Honam, 5 to 40 mm in southern Gyeonggi, Chungcheong, western Gyeongsangbuk-do, and western Gyeongsangnam-do, and around 5 mm in the mountainous and central areas of Jeju.
In the afternoon, ozone levels in the metropolitan area, Chungcheong, Honam, and Gyeongnam are expected to reach 'bad' levels, so caution is advised.
