South Korea Coastal Regions Hit by Extreme Rainfall

Extreme rainfall is battering the coastal and mountainous regions of South Korea, prompting urgent safety warnings for residents in Geoje, Busan, and Tongyeong [1, 2].

The intensity of the storms creates significant risks of flooding and landslides in these specific geographic zones. Because the rain is concentrated in areas where the sea meets mountainous terrain, the potential for rapid environmental degradation and infrastructure failure is heightened.

Professor Baek Seung-ju of the Department of Fire and Disaster Prevention at Open Cyber University explained the meteorological cause of the event during a Tuesday broadcast [1, 2]. Baek said the weather is the result of an interaction between a high-pressure system over the East Sea and a rising low-pressure system linked to the remnants of Typhoon Dolphin [1, 2].

This interaction created a lower-level jet stream that stalled over the region. Baek said that as the system stagnated, large rain clouds formed on an hourly basis, while the jet stream brought heavy wind and rain specifically to the Geoje and Tongyeong areas [1, 2].

Public safety officials are urging residents to minimize movement to avoid accidents during the peak of the storm. Baek said people should refrain from traveling unless the movement is absolutely necessary [1, 2].

Local authorities continue to monitor the coastal-mountainous corridors where the stalled system is most active. The combination of typhoon remnants and high-pressure systems has created a persistent weather pattern that resists quick dispersal, leaving the southern coast vulnerable to continued deluge [1, 2].
