South Korean weather officials issued a heavy rain warning for the mountainous regions of Jeju Island as strong storms sweep across the nation [1].
These weather patterns pose a significant risk of flash flooding and landslides, particularly in high-altitude areas and coastal regions. The intensity of the rainfall threatens infrastructure and public safety during the early-June seasonal transition [1].
YTN weather reporters said rainfall in Jeju's mountainous areas is expected to reach at least 150mm by June 21 [1]. Other reports indicate that the maximum recorded rainfall in these same mountainous regions could reach as high as 250mm [3].
The storm is not limited to the south. Strong wind and rain have affected much of the country, including the capital city of Seoul [2].
In the south coast and Jeju areas, the intensity of the precipitation is expected to be particularly severe. Reporters said hourly maximum rainfall in these regions could reach up to 50mm per hour [2].
Local authorities are monitoring the situation as the seasonal weather pattern brings volatile conditions to the peninsula. Residents in the affected areas have been advised to remain vigilant of weather updates and avoid mountainous terrain during the peak of the storm [1].
“Jeju mountainous area expected rainfall of at least 150mm”
The variance in rainfall forecasts—ranging from 150mm to 250mm—highlights the volatility of early-June weather patterns in South Korea. When combined with high hourly intensity, these totals significantly increase the risk of soil saturation and landslides in Jeju's rugged terrain, necessitating high-level emergency preparedness.
