Light rain is expected in the southern coastal areas of Jeonnam until dawn and in Jeju Island until the morning.

The forecast rainfall for the two days from the 28th is 10-40 mm for Gwangju and Jeonnam, and 10-60 mm for Jeju Island.

There will be scattered showers of around 5 mm in the late afternoon in northern Chungbuk and the northeastern mountainous areas of Gyeongbuk.

Morning low temperatures are expected to be between 15-20 degrees Celsius, and daytime highs between 23-27 degrees Celsius.

Fine dust concentrations are expected to be 'good' to 'normal' nationwide due to smooth air diffusion.
