South Korea Issues First Extreme Heat Warning

South Korea has issued its first Extreme Heat Warning under a new top-tier alert system, with the highest-level warnings covering the southeastern cities of Gyeongsan and Pohang.

According to government officials, the warnings took effect at 10:00 a.m. on Sunday after temperatures reached 39.9°C in Gyeongsan and 37.2°C in Pohang the previous day. Temperatures in both cities are forecast to climb to around 39°C again on Sunday.

The alerts are the first issued since the government introduced its new heat warning system on 1 June to improve public preparedness for extreme temperatures.

Under the new system, an Extreme Heat Warning is issued when daily maximum temperatures are forecast to reach 39°C in areas where the heat index has remained at 35°C or higher for at least two consecutive days.

Authorities have advised residents to avoid outdoor activities, stay in shaded areas and drink plenty of water during the extreme heat.
