[Asia Economy Reporter Han Jinju] Heavy rain of up to 250mm is expected mainly in the central region until the 30th. The rain is expected to weaken during the daytime and then intensify again from night.

On the 29th, the Korea Meteorological Administration (KMA) forecasted rain nationwide until tomorrow, with heavy rainfall of about 30 to 50mm per hour in the central region. As of 8 a.m., the KMA issued a heavy rain advisory for Sejong, Gyeryong and Nonsan in Chungnam, and Iksan, Gimje, and Gunsan in Jeonbuk.

Areas with heavy rain in the metropolitan area and inland and mountainous areas of Gangwon are expected to receive more than 250mm, while the metropolitan area, Chungnam region, and central to northern Chungbuk are expected to receive about 50 to 150mm of rain.

Northwestern Jeonbuk and northern inland Gyeongbuk are expected to receive over 100mm, southern Chungbuk, Jeonbuk, and northern inland Gyeongbuk 30 to 80mm, and the east coast of Gangwon, Jeonnam region, Gyeongbuk region, Gyeongnam region, mountainous areas of Jeju Island, the five western islands of the West Sea, Ulleungdo, and Dokdo are expected to receive 10 to 60mm.

The KMA stated, "Due to recent heavy rain in North Korea’s Hwanghae Province and Gangwon Province, river water levels near Imjingang and Hantangang in northern Gyeonggi and northwestern Gangwon Yeongseo may suddenly rise and flow speeds may increase rapidly," and urged, "Special caution is needed to prevent accidents involving campers and vacationers, loss of vessels, and downstream flooding."

The KMA analyzed that the rainfall intensity is very strong as a low-pressure system combines with the stationary front and warm air inflow. From the night of the 29th to the 30th, heavier and more concentrated rain than the previous day is expected in the central region.

The intensity of the rain cloud band fluctuates, causing significant differences in rainfall amounts by region. Warm and humid southwesterly winds flow along the edge of the North Pacific High, while cold and dry air from the northwest causes the stationary front to move up and down north-south, resulting in high variability in rainfall areas and intensity.

The highest daytime temperature on the 29th will be between 25 and 32 degrees Celsius. Daegu, Gyeongbuk, and Jeju Island, where heatwave warnings are in effect, will experience very hot conditions with a maximum perceived temperature of 33 degrees or higher. Tropical nights are expected mainly along parts of the east coast, Jeju coastal areas, Chungcheong region, and southern inland areas for the time being.

Strong wind warnings are in effect for Seoul, Incheon, western Gyeonggi, eastern Gangwon coast, Gangwon mountainous areas, western Chungnam, Jeolla coast, Gyeongnam coastal areas, and mountainous areas of Jeju Island, with winds blowing very strongly at 10 to 16 meters per second until the morning. Many places will experience strong gusts exceeding 15 meters per second until tomorrow morning.

In the West Sea, East Sea offshore, southwestern South Sea offshore, and Jeju waters, where storm warnings are in effect, winds will blow very strongly until the afternoon, and waves will rise very high at 2 to 4 meters, requiring caution for navigation and fishing operations.
