Heavy rain and strong winds have spread across South Korea as a stationary front moves northward [1, 2].
The weather system poses a significant risk of flooding and infrastructure damage, particularly in mountainous regions and densely populated urban centers like Seoul.
Meteorologists report that the temporary northward movement of the stationary front is driving the widespread precipitation [1, 2]. This movement has expanded the reach of the storm from the southern regions and Jeju Island toward the central parts of the country [1].
In the mountainous areas of Jeju Island, officials have issued a heavy-rain warning [1]. Forecasts indicate that these regions could receive over 100mm of rain during the night [1]. Local intensity in Jeju's mountains is expected to reach around 30mm per hour [1].
The storm has also reached the capital region. Seoul is expected to see a maximum of 80mm of rainfall [1]. Many other areas across the country are experiencing hourly rainfall intensity between 20 and 30mm per hour [1].
"As the stationary front temporarily moves north, wind and rain are expanding to the central regions, including Seoul, following Jeju Island and the southern districts," an anchor for YTN News said [1].
Reporter Jung Hye-yoon of YTN News said that the heavy rain forecast for the Seoul metropolitan area remains at a maximum of 80mm [1]. Jung said the wind and rain are continuing to expand nationwide [1].
“Seoul is expected to see a maximum of 80mm of rainfall.”
The movement of a stationary front often signals the onset of the East Asian rainy season, where moisture-laden air clashes with colder air masses. When these fronts stall or move slowly, they can trigger extreme localized precipitation, increasing the risk of landslides in mountainous terrain and urban flash flooding in cities like Seoul.
