In particular, in the case of Seoul, a heat wave warning has been issued again after 11 days. The heat wave warning was issued at 10 a.m. on the 7th, and it was maintained for seven days until it was downgraded to a heat wave advisory at 10 a.m. on the 13th. The Seoul City government elevated the crisis alert level from 'caution' to 'alert' and is preparing for heat wave damage through measures such as stockpiling cooling and emergency relief supplies.
A heat wave warning is issued when the maximum perceived temperature is expected to remain above 35 degrees Celsius for more than two days. A heat wave advisory has a threshold of 33 degrees Celsius. Even if significant damage is expected from the heat, a heat wave advisory may be issued.
With the North Pacific High Pressure occupying the mid-to-upper layers of the Korean Peninsula, the Tibetan High Pressure is expected to expand its influence and cover Korea in double layers. The highest daytime temperature is expected to be between 32 and 36 degrees Celsius. This is about 3 degrees higher than the normal daytime temperature (29 to 33 degrees). For the time being, such extreme heat is expected to continue. The highest daytime temperatures are forecasted to be ▲31 to 37 degrees on the 25th ▲32 to 38 degrees on the 26th ▲31 to 37 degrees on the 27th.
