South Korea is bracing for extreme rainfall and strong winds across its central-northern regions and the Seoul metropolitan area starting Tuesday night [1].
These weather conditions pose a significant risk to urban infrastructure and public safety, particularly in densely populated areas where rapid flooding can occur. The timing of the storm is critical as it coincides with the overnight hours of July 14 and early July 15 [1].
According to reports from YTN, the severe weather is the result of moisture and rain clouds left behind by a recent typhoon [1]. Forecasters expect the most intense period of precipitation to occur overnight, which will be the peak of the storm's impact [1].
In the central-northern region, including Seoul and western coastal areas, officials have warned of an extreme rainfall rate of 50 mm per hour [1]. The total rainfall is expected to reach 120 mm or more [1].
"Due to the influence of rain clouds left by the typhoon, heavy rain of up to 120 mm or more, accompanied by gusts, will fall across the country until tomorrow," a YTN anchor said [1].
Seoul has also been placed under a strong-wind warning to alert residents of potentially dangerous gusts [1]. The meteorological alert remains valid through the following day as the system moves through the peninsula [1].
"Extreme heavy rain of more than 50 mm per hour is forecast for the metropolitan area and central-northern regions, and the overnight period is expected to be the maximum crisis," a YTN anchor said [1].
Local authorities are monitoring the situation closely to prevent casualties and property damage caused by the sudden influx of water and wind [1].
“Extreme heavy rain of more than 50 mm per hour is forecast for the metropolitan area”
The convergence of lingering typhoon moisture and high-intensity hourly rainfall rates increases the likelihood of flash flooding in Seoul's urban corridors. Because the peak intensity is forecast for the overnight hours, the risk to commuters and residents is amplified by reduced visibility and slower emergency response times.
