Currently, areas where rain is concentrated are Seoul, Gyeonggi and Gangwon.

With strong rain clouds rising slightly norther than yesterday, thunder and lightning strike these areas, pouring about 20 to 50 mm of rain per hour.

Over the last night, over 250mm of rain poured down in Yeoncheon Sinseo, and 51mm of rain fell in Cheorwon 238, Hwacheon 161, Pocheon 141, and Namhyeon-dong, Seoul.

The rainy season is expected to rain in the middle of the region for some time.

First of all, there will be more rain from 100 to up to 300mm in the central region by tomorrow, and rain from up to 100mm is also expected in Yeongdong, Gangwon and northern Gyeongbuk.

The problem is the number 4 typhoon'Hagupit', which is heading north from the east coast of Taiwan.

It is far from the Korean Peninsula and is a weak typhoon, but it supplies hot water from the tropics to the rainy season.

The Korea Meteorological Administration predicted that the cumulative precipitation of more than 500 mm to the day after day was added due to the addition of hot water vapor supplied by the typhoon.

In particular, if a large amount of water vapor is supplied after the typhoon has disappeared, there is a possibility of heavy rains in the second half of this week.

The Meteorological Administration said the rainy season in the central region is expected to continue for at least another week in the future, so it is highly likely that this summer will be the longest rainy season ever.
