The Korea Meteorological Administration issued an extreme heat major warning starting at 11 a.m. on the 26th for Dalseong South and Dalseong North in Daegu, central Daegu, and Gimhae, Miryang, Haman, Changnyeong, and central Hapcheon in South Gyeongsang.
In areas already under a major warning, including Gwangyang in South Jeolla; Goryeong, Pohang, and Gyeongju in North Gyeongsang; and Yangsan and Uiryeong in South Gyeongsang, the maximum heat index is expected to reach 38 degrees, and temperatures in some areas are forecast to rise above 39 degrees.
The Korea Meteorological Administration said, "An extreme level of heat that threatens lives is expected."
The extreme heat major warning is the highest level in the heat advisory system introduced for the first time this year, and is issued when, in areas where a maximum heat index of 35 degrees or higher persists for two or more days, the maximum heat index reaches 38 degrees or higher or the maximum temperature reaches 39 degrees or higher.
On Jeju Island; in Dongducheon, Gyeonggi; in southern Goseong and Hadong in South Gyeongsang; and in the plains of Samcheok and Donghae and the mountainous areas of Samcheok in Gangwon, a heat warning was issued. A heat warning is issued when a maximum heat index above 35 degrees persists for two or more days or when significant damage from heat is anticipated.
In Busan and Ulsan and most parts of South Gyeongsang, tropical nights, in which the nighttime low stays at 25 degrees or higher, are also expected to continue.
The Korea Disease Control and Prevention Agency urged people in areas under the extreme heat major warning to immediately stop or postpone work in rice paddies and fields and at construction sites, as well as exercise and outdoor events.
When a major warning is issued, the "stop, move, check" rules must be followed. Immediately stop outdoor activities and work, move to a cool place such as an air-conditioned facility, a cooling shelter, or shade, and rest while drinking water. Even if you do not feel thirsty, you should hydrate regularly. However, people with kidney disease should consult a doctor about their water intake.
If you develop a headache, dizziness, nausea, or muscle cramps, stop activities immediately and cool your body. If symptoms of heatstroke appear, such as impaired consciousness or a hot body without sweating, do not delay and call 119. The Disease Control Agency urged neighbors to frequently check on seniors living alone, people with disabilities, pregnant women, children, and people with underlying conditions.
