Overview
- The Korea Meteorological Administration issued its first highest‑level emergency or “grave” heatwave warning for Gyeongsan and Pohang on Sunday after weekend readings reached near 40°C.
- Under the new three‑tier system introduced in June, the emergency warning is used when perceived temperatures are forecast above 38°C after two days over 35°C or when air temperature is expected to exceed 39°C.
- Health authorities reported a sharp rise in heat illnesses with 99 emergency‑room visits nationwide on Saturday, and officials warned even healthy people face elevated risk under emergency levels.
- The Ministry of the Interior and Safety launched an interministerial response, dispatched on‑site officials, urged suspension of outdoor work, extended heat‑shelter hours and ordered checks on the elderly and other vulnerable people.
- KMA data show the average annual number of heatwave days has more than doubled since the 1970s and experts link the trend to changing circulation patterns and the return of El Niño, raising the risk of more frequent extreme warnings.
