Wednesday, the 13th, will be generally cloudy nationwide, with rain expected in most areas. The southern regions may show a lull from early morning into the afternoon, and by night, rain will cease in most areas.
According to the Korea Meteorological Administration, the expected rainfall over the next two days starting on the 13th is 50 to 120 mm in Seoul and Gyeonggi, over 150 mm in Incheon, northern Gyeonggi, and the five islands of the West Sea, 30 to 100 mm in inland and mountainous areas of Gangwon, 10 to 40 mm along the northern coast of Gangwon, and 5 to 20 mm along the central and southern coast of Gangwon. In Gwangju and Jeonnam, Busan, Ulsan, and Gyeongnam, along with Daegu and Gyeongbuk, rainfall is expected to be 10 to 80 mm (with some places like the Jeonnam coast exceeding 100 mm), and the mountain areas of Jeju Island are expected to receive 20 to 60 mm.
The morning low temperatures are forecasted to be between 22 and 26 degrees Celsius, while the daytime highs are expected to reach 27 to 33 degrees. Although temperatures may temporarily drop in areas experiencing rain or showers, the perceived temperature in the southern regions will rise above 33 degrees, making it feel hot.
Strong winds, with gusts reaching up to 55 km/h (15 m/s), may occur primarily along the West Coast and in central inland areas, so attention should be paid to facility management and safety accidents.
Dust concentrations are expected to be at a 'good' level across all regions due to smooth atmospheric dispersion and rainfall.
Waves in the East Sea, West Sea, and South Sea are expected to rise to 1.5 to 3.5 meters, likely prompting a gale warning. Additionally, gusts of wind along with thunder and lightning are possible in most maritime areas.
Along the southern coast and Jeju coastal areas, strong swells may result in high waves that could overflow onto tidal flats, breakwaters, and coastal roads, so beachgoers should be especially cautious to avoid accidents.
