Seoul to hit 39C as heatwave grips South Korea; Gangwon braces for heavy rain

South Korea is bracing for another day of intense heat, with temperatures in Seoul and surrounding areas expected to soar to 39 degrees Celsius (102 Fahrenheit). The Korea Meteorological Administration has issued "heatwave critical warnings" for regions including the capital, parts of Gangwon Province, and Jeolla Province, forecasting that the highest perceived temperatures will reach around 35 degrees Celsius nationwide.

Specific cities like Seoul, Chuncheon, and Jeonju are projected to hit 39 degrees Celsius, while Incheon and Daejeon anticipate 38 and 37 degrees, respectively. The heat is expected to persist overnight, with tropical nights, where minimum temperatures remain above 25 degrees Celsius, likely in many areas.

Meanwhile, a significant shift in weather is anticipated for the eastern coast of Gangwon Province. Starting Saturday morning and continuing through Sunday, the region is forecast to receive 30 to 100 millimeters of rain, with some areas potentially seeing over 150 millimeters. The forecast includes the possibility of very heavy rainfall, with hourly rates of 30 to 50 millimeters between Saturday morning and afternoon, raising concerns about landslides and flooding.

Coastal areas, particularly around Jeju Island and the southern sea, are also experiencing strong winds and high waves due to a nearby weather system. Waves are expected to reach 2 to 4 meters, potentially exceeding 5 meters in some locations, and coastal areas may see waves washing over breakwaters and rocks.
