For most workers, the holiday 'Labor Day' on the 1st will bring rain nationwide. Strong winds accompanied by thunder and lightning will occur, and some areas may experience sleet.
According to the Korea Meteorological Administration, the expected rainfall on this day is 20–60 mm in northwestern Gyeonggi, 10–50 mm in the capital region (excluding northwestern Gyeonggi), along the coast of Jeonnam and eastern inland areas, along the western coast of Jeonbuk, in Busan and southern Gyeongnam, southwestern inland Gyeongnam, and Jeju Island, and 10–40 mm in inland and mountainous areas of Gangwon, in the Chungcheong region, in the inland areas of Gwangju and Jeonnam (excluding eastern inland), and in the inland of Jeonbuk, and 5–10 mm in the eastern coast of Gangwon, and in the inland areas of Daegu and southeastern Gyeongbuk.
There will be areas where thunder and lightning occur, and in some regions, sleet with a diameter of less than 5 mm may fall. The rain will reduce visibility and make roads slippery, so caution is advised. The rain is expected to mostly stop by tomorrow.
As of 6 a.m. that day, the temperatures in major areas are as follows: Seoul 16.6°C, Incheon 15.7°C, Suwon 13.5°C, Chuncheon 7.8°C, Gangneung 14.6°C, Cheongju 15°C, Daejeon 11.1°C, Jeonju 16.5°C, Gwangju 16.3°C, Jeju 15°C, Daegu 11.5°C, Busan 16.3°C, Ulsan 14.3°C, and Changwon 13.9°C. The highest daytime temperature is forecasted to be between 16°C and 25°C.
In the western coast of Jeonbuk, Jeju Island, and the mountains of Gangwon, wind gusts of 70 km/h (20 m/s) or more are expected, so caution should be taken for facility damage and pedestrian safety. The sea waves will range from 0.5 to 3.5 m in the eastern sea, from 1.0 to 3.5 m in the western sea, and from 0.5 to 2.0 m in the southern sea. The wave height in the deep sea (approximately 200 km from the coastline) is forecasted to be 1.0 to 4.0 m in the eastern sea, 1.0 to 3.5 m in the western sea, and 0.5 to 3.5 m in the southern sea.
The concentration of fine dust is expected to be at a 'good' level in all regions due to smooth atmospheric diffusion and rain.
