South Korea issues urgent heat warnings as extreme temperatures hit the country’s southeast and set record levels. Multiple outlets report that temperatures reach about 42.5°C on Sunday, described as the highest ever recorded in South Korea. The government urges people to respond immediately to the heat risk, including taking protective measures during the hottest periods. The reports also say the heat wave has already caused fatalities: at least 13 people die in connection with the extreme conditions in the affected area. Authorities warn that the danger remains high as temperatures stay elevated and advise residents to avoid prolonged outdoor exposure, stay hydrated, and check on vulnerable people such as older adults and those with health conditions. Emergency and public health responses are continuing as officials monitor heat-related incidents and adjust guidance. While the reported impacts are concentrated in the southeast, the warnings apply more broadly as the heat wave affects wider parts of the country.
