Seoul, Gangwon Expect Heavy Rain, Heat Wave
South Korea faces an unprecedented transition from heavy monsoon downpours to a dangerous heatwave, with the Korea Meteorological Administration issuing its first Emergency Heatwave Warning as temperatures push toward the high 30s and beyond, while heavy rainfall of 20–80 mm persists in Seoul, Gangwon, and surrounding regions. Authorities warn of tropical nights, heat advisories across the east coast of Gangwon and other regions, and a continued pattern of extreme weather as monsoon rains taper and heat intensifies.
