Tomorrow (4th), which is Tuesday, from late afternoon to 6th, sweet rain will wet the whole country.

In Jeonnam, where the severe drought continues, it will rain enough to relieve the dryness, such as up to 80 mm.

A low pressure system that has developed in central China is moving northeast and approaching Korea, and rain will fall across the country from late afternoon to 6 tomorrow.

Due to the low pressure, there will be a lot of precipitation especially near Jeju, the south coast, and Jirisan, where warm and very humid southwest winds hit the mountains.

In the Jeju Mountains, precipitation is expected to exceed 200mm on 4~6 days.

Up to 120 mm or more is expected to fall in southern Jeju, southeastern Jeolla coast, south coast of Gyeongsangnam, and near Jirisan.

The overall estimated rainfall is 30~80mm in Jeolnam, Jeju (excluding the northern coast), West Sea 5°C, South Gyeongsang coast, and southwest Gyeongsang inland, 20~60mm in the Seoul metropolitan area, inland Gangwon, Chungnam, North Jeolla, North Gyeongsang and South Gyeongsang (excluding the south coast and southwest inland), and 10~40mm in Gangwon East Sea an, North Chungcheong, and Jeju North coast, North Gyeongsang (excluding the northern inland), Ulleungdo, and Dokdo.

The heaviest rain is expected to fall from morning to night on the 5th.

At this time, Jeju, the south coast, and the vicinity of Jirisan will receive torrential rain of 20~30mm per hour.

Regarding this rain, the lower jets, which are fast winds blowing 1.5 km in the air, are blowing stronger than expected from the south to the north, and if more water vapor is supplied, there is a possibility of increasing precipitation near Jeju, the south coast, and Jirisan.

In addition, due to the "secondary pressure trough" that develops behind the low pressure after the low pressure, light rain may continue until the 7th, mainly in the central inland.

The atmosphere has been very dry in recent years as sunny days continue under the influence of high pressure.

A dry warning has been issued for Seoul and Daejeon, and a special dry advisory has been issued for almost the entire country.

The atmosphere has become so dry that there were more than 30 wildfires across the country yesterday.

Looking at the number of non-precipitation days at 66 weather observation points nationwide, the minimum number of days (Seongsan, Jeju) and the maximum of 84 days (Andong, North Gyeongsang) as of the 1st of this month is the same.

In the places where it rained most often, less than half of the 90 or so far this year.

This year's cumulative precipitation was 84.4 mm by the 1st of this month, which is only 67.3% of the cumulative rainfall of a normal year (121.1 mm).

Cumulative precipitation from Jan. 1 to April 1 is the ninth lowest in 51 years since 1973.

Until it starts raining this time, the atmosphere will be very dry, and there is always the possibility of large fires such as forest fires, so be careful.

Also, after a very busy day, the spring falls with heavy rains, which can lead to landslides and collapses in areas where recent wildfires have occurred.

In addition, strong winds will blow all over the country on the 4th~6th, and the entire sea may be harsh.

In island areas such as Jeju, flights and ferries may be cut off, so be sure to check the flight information in advance.

Temperatures will be higher than normal until tomorrow, and then will decline as rain falls.

Especially as the whole country becomes cloudy, the temperature difference between day and night will decrease.

After the 7th, cold air will flow in due to the influence of continental high pressure, and the temperature will drop to a level below normal.

Especially in the central inland, cold seas may occur as temperatures drop below freezing.
