The expected rainfall in the Seoul metropolitan area on the 9th and 10th is 50 to 100mm (over 120mm in some places) in Seoul, Incheon, and Gyeonggi, over 150mm in southern Gyeonggi, and 20 to 60mm in the five western islands (Seohae 5do).

Additionally, 50 to 100mm of rain is expected in inland and mountainous areas of Gangwon, the central and southern east coast of Gangwon, and the Chungcheong region; 30 to 80mm in the northern east coast of Gangwon, Jeolla region, and Gyeongsang region; 20 to 80mm in Jeju Island; and 20 to 60mm in Ulleungdo and Dokdo. Among these, some places may receive more than 150mm of rain.

Since very heavy and substantial rainfall is expected, sudden flooding may occur downstream due to rain falling in valleys or upstream of rivers, so camping should be avoided.

The morning low temperature is forecast to be between 21 and 25 degrees Celsius, and the daytime high temperature between 24 and 30 degrees Celsius.

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

Sea waves will range from 0.5 to 2.5 meters in the coastal waters of the East Sea, West Sea, and South Sea.

Wave heights in the offshore waters (about 200km from the coastline) are predicted to be 1.5 to 3.5 meters in the East Sea, 1.0 to 3.5 meters in the West Sea, and 1.5 to 4.0 meters in the South Sea.
