South Korea is experiencing nationwide rain and cloudy skies with gusty winds and lightning expected to continue through the morning [1].

These weather conditions create significant hazards for commuters and road users across the peninsula, particularly in high-altitude regions where heavy precipitation is forecast.

Weather officials have issued heavy rain warnings for mountainous areas. The Gangwon east coast and mountain regions are expected to see maximum rainfall of 80 mm [1]. Other high-elevation areas, including the North-East Gyeongbuk mountain regions, may receive up to 40 mm [1].

Inland areas are seeing more moderate precipitation, with rainfall estimates ranging from five to 30 mm [1]. The system is affecting a wide geographical area, including Seoul's Sangam-dong, the central region, and Jeju [1, 2].

Temperatures remain mild across the country. The daytime high in Seoul is forecast to be 20 °C [1], while Gwangju is expected to reach 21 °C [1].

Authorities said residents should remain vigilant of lightning and sudden wind gusts as the system moves through the region [1, 2].

The concentration of heavy rainfall in mountainous zones increases the immediate risk of landslides and flash floods, which often disrupt critical transport arteries in South Korea's rugged interior. While urban centers face moderate rain, the combination of lightning and gusty winds suggests an unstable atmospheric system that could lead to localized power outages or transit delays during the morning commute.
