South Korea is preparing for heavy rain and strong winds starting Tuesday morning through Wednesday dawn [1].
This weather shift follows a period of extreme heat and poses significant risks of flooding and wind damage across several regions. The Korea Meteorological Administration has issued strong-wind warnings as a low-pressure system moves through North Korea toward the peninsula [1].
Byeon Ga-young, a forecast analyst at the Korea Meteorological Administration, said rain will fall nationwide due to the influence of the low-pressure system passing to the north. She said that some central regions may experience very heavy rain accompanied by gusts, thunder, and lightning between Tuesday night and Wednesday dawn [1].
The system is driven by rain clouds moving from China and a strong low-pressure center passing through North Korea [2]. This atmospheric instability is expected to produce hourly rainfall exceeding 50mm in some areas [2]. Northern Gyeonggi and northern Gangwon provinces are projected to receive more than 120mm of precipitation [1].
Border regions along the Imjin and Hantan rivers are also under alert. These warnings follow a stretch of intense heat in various cities. Temperatures in Daegu Dong-gu and Hayang-eup in Gyeongsan reached approximately 38°C [2]. Meanwhile, temperatures in Nowon-gu, Seoul, exceeded 35°C [2].
Authorities are monitoring the potential for sudden flooding as the system moves. The combination of high-velocity winds and heavy precipitation increases the risk of infrastructure damage in the northern regions [1].
“Rain will fall nationwide due to the influence of the low-pressure system passing to the north.”
The rapid transition from extreme heat—with temperatures hitting 38°C—to torrential rain and gale-force winds indicates high atmospheric instability. This volatility increases the likelihood of flash floods and wind-related accidents, particularly in the northern border regions and central provinces where the most intense precipitation is expected.
