Southern regions brace for continued heavy rain; scattered showers nationwide with thunder and lightning expected

Southern regions of South Korea, particularly the southern coast of Gyeongnam, are bracing for continued heavy rainfall on August 18, the final day of the Liberation Day holiday. The Korea Meteorological Administration (KMA) forecasts that rain will persist until the morning in areas like Gyeongnam, southeastern Gyeongbuk, and the southern coast of Jeonnam, with Jeju Island expecting rain into the afternoon.

Currently, areas along the southern coast, eastern inland Gyeongnam, and Jeju Island are experiencing rainfall of 5 to 20 millimeters per hour. The KMA has issued warnings for potential landslides and facility collapses, especially in the southern coastal areas of Gyeongnam, where the ground is already weakened by previous downpours. Residents are urged to exercise caution.

“

Especially in the southern coastal areas of Gyeongnam, very heavy rain has fallen and the ground has weakened. Rain will continue until this morning, so please be careful of landslides, soil erosion, and facility collapses.

The current rain is attributed to a linear precipitation band that developed as moisture flowed in from the edge of a high-pressure system. This rain band is expected to shift northward on August 19, expanding the areas affected by precipitation. The KMA anticipates rain in the southern parts of Chungcheong, Jeolla, and western Gyeongbuk from early morning to mid-morning.

In the morning until noon, rain will fall in Gyeongnam-Inland, Gyeongbuk-Southeast, and Jeonnam-South Coast, and rain will fall in Jeju Island until the afternoon.

Meanwhile, unstable atmospheric conditions due to a significant temperature difference between the upper and lower atmosphere are expected to trigger scattered showers across the country. These showers could bring 5 to 60 millimeters of rain to various regions, including parts of Gyeonggi, Gangwon, Daejeon, Chungnam, Jeonnam, Gyeongnam, and Daegu.

The humid and warm air mass will also maintain the heat, with temperatures on August 18 expected to be around the annual average. Daily lows are forecast between 20.2 and 23.8 degrees Celsius, and highs between 27.1 and 31.4 degrees Celsius. Major cities like Seoul, Busan, and Daegu are expected to reach highs of around 30-32 degrees Celsius.

From the morning to the morning of the 19th, rain will fall in Chungcheong-South, Jeolla, and Gyeongbuk-West.
