[Asia Economy Reporter Hyunju Lee] The monsoon rain that began in Jeju is expanding nationwide in the afternoon.

According to the Korea Meteorological Administration on the 29th, this rain is expected to bring typhoon-level heavy rainfall depending on the terrain. Jeju Island, the southern coast, and Chungcheong Province are expected to see 30 to 50 mm per hour, while Gangwon Yeongdong and the northeastern mountainous areas of Gyeongbuk are forecasted to experience heavy rain exceeding 80 mm. Some areas in Chungcheong, Jeonbuk, Gyeongnam, and Gyeonggi, including Daejeon and Sejong City, will have preliminary heavy rain warnings issued starting from tonight.

Heavy Rain Warning

The amount of rainfall is also expected to vary significantly by region. The expected precipitation amounts are 50 to 100 mm in the central region (excluding Gangwon Yeongdong), northern Gyeongbuk, northern Jeonbuk, southern coast of Jeonnam, southern coast of Gyeongnam, and Jeju. Southern Gyeongbuk, southern Jeonbuk, Jeonnam (excluding the southern coast), and inland Gyeongnam are expected to receive 30 to 80 mm.

The expected rainfall in Gangwon Yeongdong and the eastern coast of Gyeongbuk, where rain will continue until the morning of the day after tomorrow, is forecasted to reach 100 to 200 mm. Some areas may receive more than 300 mm. Chungcheong, the southern coast, the Jirisan area, and the northeastern mountainous areas of Gyeongbuk are also forecasted to receive heavy rain exceeding 150 mm due to terrain effects.

Flooding in low-lying and agricultural areas and landslides are concerns due to this. A Korea Meteorological Administration official said, "Since the rain is localized and changes rapidly in a short time, it is necessary to frequently check ultra-short-term forecasts," and added, "Please be especially cautious of safety accidents as valleys and rivers can suddenly swell."

Meanwhile, with rain falling nationwide, temperatures will not rise significantly. The highest daytime temperatures will be 2 to 5 degrees lower than the previous day. Today's highest daytime temperature is expected to be 23 to 29 degrees nationwide. Tomorrow's highest daytime temperature is also expected to be 21 to 27 degrees, not exceeding 30 degrees. However, the perceived temperature due to high humidity will be about 2 to 3 degrees higher than the actual highest temperature.
