Let's find out how long this rainstorm, which I want to stop coming from now, and where to be careful tonight, together with reporter Seo Dong-gyun.

Rain clouds keep moving and come and go soon, but in which area is it raining the most?


I will explain while looking at the current radar.

The colored part is the part where it is currently raining, and the red part is where the heavy rain of 20mm per hour is concentrated.

At a glance, you can see that the rain is concentrated in the metropolitan area and Gangwon-do.

Let's take a look at the amount of rain that has fallen so far.

In the metropolitan area such as Seoul, it rained a lot of 300-400mm.

In Dongjak-gu, Seoul, 453 mm of rain fell.

As of 6pm, it is still raining, so this number is expected to increase.

In the case of Dongjak-gu, Seoul, it fell 141 mm per hour at one point last night, setting the record for the most rainy night in the history of meteorological observations.

The characteristic of this rain is that it is narrow from north to south, long from east to west, and concentrated during the night.

Since 8 pm yesterday, 244mm has fallen in Seocho-dong, Seoul, but only 48mm has fallen in Jung-gu, which is only 7.5km to the north.


As reporter Seo Dong-gyun just mentioned, it seems to have a characteristic that it rains a lot at night.

So can it rain as much tonight as it did yesterday?


As you saw earlier, it's raining a lot on the radar, so I'm worried about it tonight.

The Korea Meteorological Administration has already predicted a lot of rain of 50 to 100 mm per hour centering on the metropolitan area tonight.

In Seoul, there were areas where it rained more than 400mm.

300mm, or more than 70%, were concentrated in these areas overnight.

This is because the water vapor that makes rain clouds is smoothly supplied at night.

During the daytime, the surface overheats, creating turbulence, which blocks the supply of water vapor.

However, at night, this turbulence disappears and the supply of water vapor becomes smoother, and sources that can make rain clouds explosively continue to come in.

At night, as the temperature drops again, the amount of water vapor that the air mass can hold decreases, making it easy to form raindrops.

The rest of the weather news will be provided shortly.
