SEOUL, March 30 (AJP) - Morning air across the Korean Peninsula remained crisp Monday even as the state weather administration warned that a significant frontal system will bring heavy rain and volatile conditions through Tuesday.


While Seoul and inland regions recorded morning lows as low as 4 degrees Celsius, daytime highs are expected to surge to 22 degrees, creating a 15-degree thermal gap that officials say poses a legitimate risk to public health and agricultural stability.

The disruption marks a sharp transition from the dry, clear conditions of recent days, with clouds expected to thicken by the evening as a weather system strikes Jeju Island and the southern coast with the greatest intensity.

The southern resort island of Jeju sits in the direct path of the most severe rainfall, with projections reaching 80 mm across the province and more than 120 mm in high-altitude mountainous regions.

Further north, Jeolla and Gyeongsang provinces are bracing for 20 to 50 mm of rain, though coastal hubs including Busan and Ulsan could see totals exceeding 60 mm.

Beyond the immediate precipitation, the primary concern for the interior remains the persistence of massive temperature fluctuations. Officials advised the public to take specific precautions to protect their health, noting that such 15-degree swings are particularly taxing on the respiratory system.
