At 10 a.m. on the 12th, the Korea Meteorological Agency issued the highest-level high temperature warning for Gyeongsan City and Pohang City in southeastern Gyeongsangbuk-do, advising people to immediately stop outdoor activities, move to a cool place, and stay hydrated. No one or pets should stay in an airtight compartment. This is the first time that South Korea has issued the highest-level high temperature warning since upgrading its high temperature warning system last month. South Korea's high temperature warning system was originally only divided into two levels. In order to adapt to increasingly frequent extreme weather, the system established a new highest-level “high temperature major warning”, which came into effect on June 1. The condition for issuing a “Major High Temperature Warning” is that in regions where the highest sensed temperature reaches 35 degrees Celsius and above for two consecutive days, the maximum sensed temperature is expected to reach 38 degrees Celsius or above, or the actual maximum temperature is 39 degrees Celsius and above.
