The expected rainfall over two days from the 18th is 30 to 100 mm in the Seoul metropolitan area, Gangwon Province, Chungcheong region, and Jeolla region (with some areas exceeding 150 mm, and northern Gyeonggi exceeding 180 mm). During the same period, the northern Gyeongsangbuk-do, Daegu, southern Gyeongsangbuk-do, Busan, Ulsan, and Gyeongsangnam-do areas are forecasted to receive 30 to 80 mm of rain, while Jeju Island is expected to get 5 to 40 mm.

Inland areas of the Gyeongsang region are predicted to experience heavy rain of 20 to 30 mm per hour during the early morning of the 19th. Due to the stationary front causing continuous rain, there is a risk of damage such as facility collapses and water backflow in sewage and drainage systems, so special caution is advised.

After the rain stops in most areas, the humidity will remain high and temperatures will rise again, resulting in hot weather. Especially in the Jeonnam region and Jeju Island, the highest perceived temperature will rise above 33 degrees Celsius, making it very hot, so it is advisable to be cautious of heat-related illnesses.

The morning low temperatures are forecasted to be between 21 and 26 degrees Celsius, and the daytime highs between 27 and 33 degrees Celsius.

Fine dust levels are expected to be 'Good' nationwide due to smooth atmospheric dispersion and the influence of precipitation.

Sea waves will be 0.5 to 2.0 meters in the East Sea and South Sea coastal waters, and 0.5 to 1.5 meters in the West Sea coastal waters.

Wave heights in the offshore waters (about 200 km from the coastline) are expected to be 1.0 to 3.0 meters in the East Sea and South Sea, and 0.5 to 2.0 meters in the West Sea.

For the time being, sea fog will occur in most maritime areas, and some island regions will experience dense fog with visibility less than 200 meters.

Additionally, in the southern and western maritime areas, gusts accompanied by thunder and lightning are expected, so special caution is required to prevent maritime safety accidents.
