South Korea’s Korea Meteorological Administration issues the highest-level heat wave emergency warning for the greater Seoul area as a heat wave shifts westward. The warning is first applied to parts of Seoul and nearby regions, including southeastern and southwestern districts, and expands as conditions intensify. One report says it begins at 11 a.m. Tuesday for southeastern and southwestern Seoul, along with Osan, Hanam and western Yeoju in Gyeonggi Province, and Jangseong and northern Gokseong in South Jeolla Province. Another report says the warning takes effect at 4 p.m. Monday for Tuesday and covers all Seoul districts south of the Han River, plus Osan, Hanam and western Yeoju. A separate account says the latest expansion brings the heat wave emergency designation to the entire city after earlier coverage for northeastern and northwestern districts.
Authorities cite official alert criteria based on projected perceived and/or maximum daily temperatures. Seoul experiences very high temperatures, with the capital’s daytime highs forecast to reach around 38°C and above, and the system’s threshold using perceived temperatures and actual maximums. Government data show additional heat-related illness cases in Seoul since mid-May, including deaths. During the emergency, the city monitors vulnerable residents and urges precautions, including limiting outdoor work.
