Rainfall is expected to range from 5 to 40mm in the southern regions, with up to 60mm of heavy rain forecasted for the southern coast of Jeonnam and Jeju Island.

Due to cold air in the upper atmosphere, the air remains highly unstable.

When these showers occur, they may be accompanied by gusty winds, thunder, and lightning, and some areas may even experience hail, so please take caution.
