Jeju Island's first Jangmatbi started this year.

It is raining around the coasts of Jeju and Jeonnam right now. The rain will gradually affect other nations as well.

If you look at the details of the rain, it will expand to the west in the evening (10th) and to the rest of the country at night. This rain will continue until tomorrow morning.

In the meantime, the rain is expected to be more than 100mm in the southern part of Jeju, 70mm in the Chungcheong and southern regions, and a relatively small amount of 5-30mm in the metropolitan area and Gangwon-do.

However, it is expected that very strong rain with thunderbolts and gusts will be concentrated mainly in the south of Jeju and Chungcheong provinces during the night.

Today, the heat wave coverage area has been reduced, but the heat will continue until the rain clouds come inland.

Seoul's maximum daytime temperature will rise to 32 degrees and Daegu and Gyeongsan will continue to soar to 35 degrees.

On Friday, it will start raining again in the southern region, and it is expected to expand across the country on Saturday.
