The torrential rain, which the Korea Meteorological Administration also described as 'shock and fear', is expected to continue until tomorrow (12th).

However, especially after Liberation Day, as a new stagnant front is created, heavy rain may fall with a similar intensity, although not as much as during the torrential downpour on the 8th.

If it rains again in a situation where flood damage has accumulated, the damage can be much greater, so it seems that thorough preparation is necessary.

The current stagnant front, centered in Chungcheong and Honam, will gradually weaken as it moves south.

According to today's Meteorological Administration briefing, from 11 am today to tomorrow, 30 to 100 mm in southern Chungcheong, Honam and northern Gyeongbuk, 10 to 60 mm in northern Chungcheong and southern Gyeongbuk, southern Gyeonggi, Gangwon central, southern Gangwon, Gyeongnam, and Jeju It is predicted that it will rain 5-40 mm, and less than 5 mm in Seoul, Incheon, and northern Gyeonggi.

Where it rains a lot in Honam, the amount of precipitation will be more than 120 mm.

Lee Kwang-yeon, a forecast analyst at the Korea Meteorological Administration, said at a briefing today, "It really rained at the level of 'shock and fear' on the 8th and 9th."

Currently, the tropical cyclone located in the south-southwest of Japan separates the subtropical high pressure located in the south of Korea and the North Pacific high pressure.

As the subtropical high pressure contracted, the force of hot and humid air coming from the south weakened.

At the same time, the stagnant front will be pushed down to the south by the dry air coming down from the north.

Therefore, the stagnant front will stay at its current location until this afternoon, and tomorrow it will affect the southern regions mainly.

From the 13th, the whole country will fall under the influence of high pressure.

When the subtropical high pressure expands again and enters Korea, the heat is expected to come again.

The Korea Meteorological Administration said, "From the 13th, there is a possibility that there will be a sweltering heat in South Chungcheong Province."

Some numerical forecasting models predict that a mesoscale cyclone develops in the West Sea, pushing hot and humid air from the south toward the central region.

As hot and humid air flows in, it may rain mainly in the metropolitan area.

From the 14th, as the North Pacific high pressure moves westward, hot and humid air will be raised again from the south, creating a stagnant front again on the 14th and 15th in northern China and on the border between China and North Korea.

At 9 am today, the steam left by Typhoon Muran, the 7th typhoon, weakened from the northeast of Hanoi, Vietnam to the tropical low pressure zone, will help revitalize the stagnant front.

As the stagnant front moves south, it will affect the central region of Korea again on the 16th, and the southern region the next day.

The problem is that this stagnant front is expected to be 'long from east to west and narrow from north to south' as ​​it did when the torrential rain fell this time.

The Korea Meteorological Administration explained that the level of atmospheric instability on the 16th day is similar to or worse than when it rained 141.5 mm per hour in Sindaebang-dong, Dongjak-gu, Seoul on the 8th.

On the evening of the 8th, the amount of precipitable water (when water vapor in the air condensed as rain) was about 70mm over the central region on the evening of the 8th.

However, compared to the 8th, the total precipitation is small and the time is expected to be short.

During the torrential rain this time, the high pressure on the Kamchatka Peninsula side blocked the east-west flow of the atmosphere, so the stagnant front stayed in Korea for a long time.

This 'blocking' phenomenon is expected to be resolved around the 13th, so the stagnant front will move better than before on the 16th and 17th.

Precipitation forecast for the 16th-17th will be announced on the 14th.

The Korea Meteorological Administration emphasized, "The total amount of precipitation on the 16th and 17th may be less than during the torrential downpour, but the amount of instantaneous rain may be similar or greater." .
