Autumn heavy rain with gusts is expected to fall across the country between today and tomorrow.

After the rain stops, the temperature is expected to drop significantly. We will connect reporters to find out more.

Reporter Jung Hye-yoon, when does it start raining hard?

[Reporter]
Yes, it is currently raining lightly in inland areas such as Seoul. The heavy rain is expected to start from the west coast during the day.

Heavy rain warnings have already been issued since 7 a.m., with more than 20 millimeters of rain per hour in the mountains of Jeju Island, where topographical influences overlap.

Let's check the rain situation in more detail while watching the radar video.

Rain clouds with strong low pressure are flowing inland from the western sea.

Rain clouds are accompanied by cold air to the upper layers,
Hot air flows into the south of
along strong winds.

For this reason, rain clouds are developing stronger in places as they flow into the central region.

The Korea Meteorological Administration predicted strong rain with gusts of wind in the Seoul metropolitan area, Chungcheong, Gangwon's east coast and southern coast from this afternoon to overnight.

In some areas, strong rain of around 30 to 50 millimeters per hour is likely to be concentrated, so caution is required.

By tomorrow, the weekend, the east coast of Gangwon-do and the mountains will receive up to 120mm of autumn heavy rain,
It is expected that more than 100mm of rain will fall on the southern coast such as
Busan. Seoul is expected to receive up to 60 millimeters of rain.

Along with the rain, there will be gusts of around 20m per second on the coast and inland, and there is a possibility of first snow in the mountains of Gangwon-do, where the temperature is low.

In particular, the contrast period is expected to overlap by Sunday, so it is necessary to prepare for flood damage in low-lying coastal areas.

In Jindo, Jeollanam-do, a "storm tsunami warning" was issued because the danger was expected as the sea water level rose for about an hour from 10:40 a.m.

I heard that the weather gets very cold after the rain stops.

[Reporter]
Yes, after the rain stops, the cold in the north is expected to drop sharply from daytime on the weekend.

In particular, temperatures will plunge below 10 degrees in the central interior overnight on the weekend,

It will be the coldest this fall, with 9 degrees in Seoul, 5 degrees in Paju and Cheorwon, and 4 degrees in Yeoncheon on Sunday morning.

In the mountains of Gangwon-do, the temperature drops close to zero degrees Celsius, and there are places where the rain or snow freezes over the weekend, making thin ice on the road.

Inland daytime temperatures such as Seoul will also stay below 20 degrees Celsius, making it chilly all day.

The chilly autumn weather will continue next week, with another round of rain expected across the country on Tuesday, starting with the southern part of the country on Monday.
