The Ministry of Public Administration and Security has raised the heat wave crisis warning level from 'caution' to 'alert' as of 12:00 noon today (1st).

This is 18 days earlier than last year.

A heat wave warning has been issued in 92% of 164 districts out of 178 nationwide, and it is expected that 82 or 46% will experience a daily maximum temperature of 33℃ or higher until the 4th.

The heat wave crisis warning stage is in the order of interest → caution → vigilance → serious, and the alert is issued when the maximum daily temperature of 33℃ or higher is expected to last for 3 days or more in 40% of the country.

Accordingly, the Ministry of Public Administration and Security has mandated related ministries and local governments to establish management measures for the three most vulnerable areas of heatwave: outdoor workers at construction sites, elderly workers in paddy fields, and the elderly living alone.

In fact, today Seoul, Suwon, and Incheon were the hottest this year, and Gyeongsan, Gyeongbuk, where the daytime high temperature rose to 38 degrees.

According to the Korea Meteorological Administration, the highest temperature in Seoul as of 4:25 pm today was 33.8 degrees, recorded at 4:01 pm.

The previous high this year was 32.7 degrees on the 11th of last month.

The highest temperature in Suwon-si, Gyeonggi-do was 33.7 degrees this year, and Incheon was the hottest this year at 30.6 degrees.

Tropical nights will appear everywhere tonight, and a heat wave will continue across the country tomorrow, Sunday.

The lowest temperature tomorrow morning is expected to be 21-26 degrees and the daytime high is expected to be 29-35 degrees.

The Korea Meteorological Administration (KMA) urged, "The weather is hot and there is a high possibility of heat-related diseases, so please drink plenty of water and salt and refrain from outdoor activities from 12:00 noon to 5:00 pm, the hottest time of the day."
