[Tomorrow's Weather] Cloudy Nationwide with Rain in Some Areas... Daytime Temperature Warm at 20°C

On Sunday the 21st, the whole country will be mostly cloudy with rain in some areas.

According to the Korea Meteorological Administration on the 20th, most of the rain will stop by dawn tomorrow, but rain is expected to continue until the evening in the Jeonnam region and Gyeongsang region, and until the morning of the 22nd in Gangwon Yeongdong, the eastern coast of Gyeongsang, and Jeju Island.

In Seoul, Incheon, northern Gyeonggi, and central to northern Gangwon Yeongseo, light rain will fall at dawn, and in southern Chungbuk and Jeonbuk, raindrops less than 0.1mm may fall from morning to evening.

The expected precipitation over two days from the 20th (until the 22nd on the East Coast) is around 5mm in southern Gyeonggi, Jeonbuk, Ulleungdo, and Dokdo; 5 to 10mm in Gangwon Yeongseo, Daejeon, Sejong, Chungnam, Chungbuk, Gwangju, and Jeonnam; and 5 to 20mm in Busan, Ulsan, Gyeongnam, Daegu, and Gyeongbuk. Over three days until the 22nd, 5 to 40mm of rain is expected in Gangwon Yeongdong, and around 5mm in Jeju Island.

The morning low temperature is forecast to be between 11 and 15 degrees Celsius, and the daytime high temperature between 15 and 23 degrees Celsius. Daytime temperatures will be 2 to 4 degrees higher than on the 20th (13 to 18 degrees), especially in the central regions where many places will rise above 20 degrees, but in Gangwon Yeongdong and the eastern coast of Gyeongbuk, temperatures are expected to be around 15 degrees due to the inflow of easterly winds.

Due to smooth atmospheric dispersion, fine dust concentration is expected to be at a 'good' level nationwide.

The Korea Meteorological Administration also warned that fog will form in most maritime areas, so caution is needed to prevent maritime safety accidents. The sea waves will be 1.0 to 3.0 meters in the East Sea nearshore, 0.5 to 2.0 meters in the West Sea nearshore, and 0.5 to 2.5 meters in the South Sea nearshore. The wave heights in the offshore seas (about 200 km from the coastline) are expected to be 1.0 to 4.0 meters in the East Sea, 0.5 to 3.0 meters in the West Sea, and 1.0 to 3.5 meters in the South Sea.
