The intense heatwave, which briefly seemed to subside, is intensifying once again.
Following Yangsan, South Gyeongsang Province, yesterday (August 23), temperatures in Bukchangwon soared to 37°C (99°F) today, breaking the all-time record for late August.
The cause is the North Pacific high-pressure system currently centered over Japan, which is affecting the southern regions of South Korea, combined with the upper-level Tibetan high-pressure system dominating the atmosphere.
As a result, heat advisories across most of the country, including Seoul, have been upgraded to heat warnings today. Tomorrow, perceived temperatures are expected to rise above 35°C (95°F) mainly in areas under heat warnings, bringing sweltering conditions.
Meanwhile, amid the intense heat, showers are forecasted for tomorrow, mainly centered around the greater Seoul area and Gangwon Province.
In particular, heavy showers of up to 60 mm are expected to pour down in parts of Gyeonggi Province and northern Gangwon Province.
Last night, Seoul experienced a tropical night once again after nine days.
Tonight, tropical nights with overnight lows staying above 25°C (77°F) are expected in most regions, including Seoul. Tomorrow's daytime highs are forecast to reach 32°C (90°F) in Seoul and 35°C (95°F) in Busan, with high humidity making the perceived temperatures even higher.
Fortunately, this heatwave is not expected to last very long.
Temperatures are projected to gradually decrease as rain is expected in the greater Seoul area and Gangwon Province on Wednesday, and starting in the southern regions on Friday before spreading nationwide over the weekend.
