100mm of heavy rain per hour in Gangnam, Seoul… flooding all over the road


[앵커]

hello.

Rain is pouring loudly in the metropolitan area and central regions.

The Seoul Dongjak area is now 130 millimeters per hour, the highest ever recorded in Seoul.

All roads are flooded with water.

Although the ‘Ipchu’, the threshold of autumn, has passed, the fierce rain and the scorching heat continue to rise.

First, we will connect to the KBS Disaster Media Center to learn more about the rain situation at this time.

Reporter Lee Jung-hoon! There is a lot of thunder in Seoul right now, but are you worried about whether there is any damage?

[기자]

Yes, heavy rain in Seoul is unusual.

It has been raining heavily in Gangnam, Seoul since about two hours ago.

Let’s take a look at the real-time situation with the KBS disaster monitoring CCTV.

It is near Boramae Station in Dongjak-gu, Seoul, where it rains the most.

It is currently raining at 130mm per hour.

As you can see, the road is submerged and cars are waving through it.

There is also Boramae Station on Line 7.

It is a situation in which water can enter even into the history.

Please refrain from passing vehicles and pedestrians in this area.

The following is the situation of Gangnam-daero, Seoul, a little further east.

Again, the road was filled with water up to the height of an adult’s ankle.

In fact, you can see how the road is paralyzed.

Various safety accidents such as electric shock may occur on flooded roads.

Please refrain from going out and stay in a safe place.

[앵커]

What about other areas in the metropolitan area?

[기자]

Yes, today (8th), it rained unexpectedly all over the metropolitan area.

At one time in the morning, it rained 100mm per hour in Yeoncheon, Gyeonggi Province.

Around lunchtime, in Incheon, and late in the afternoon in Paju, Gyeonggi-do, torrential downpours of around 80mm per hour fell.

This is because this narrow band-shaped rain cloud shown in the radar image repeatedly increased and weakened.

In recent times, band-shaped rain clouds are developing again in Incheon and Seoul, where strong rain clouds have escaped.

Because of this, as you saw earlier, strong rain of around 100mm per hour is concentrated around Gangnam, Seoul.

In particular, the rain clouds in these areas continue to stagnate and develop.

This situation is likely to continue for more than an hour.

The torrential downpours in the central region will be repeated until the day after tomorrow (10th).

It has been analyzed that long, thin rain clouds will pour strong, heavy rain at a rate of 50 to 80 mm per hour as they move up and down the metropolitan area, Gangwon, and northern Chungcheong.

[앵커]

Just last week, heat waves were rampant. What is the cause of the sudden downpour?

[기자]

This rain, the so-called second rainy season.

The ‘first rainy season’, which usually continues in early summer, falls in three battles between the hot North Pacific high pressure and the cold air from the north.

After the first rainy season, Korea entered a heat wave for a while. From late August to early September, the rainy season front came down again with cold air, and it was common to rain for about a week.

But this year, the so-called ‘second rainy season’ started almost a month early.

It will continue to rain in the central region in the future.

First of all, the amount of rain expected until the day after tomorrow is up to 350 mm or more in southern Gyeonggi, southern Gangwon, and northern Chungcheong, and 100 to 250 mm in most other central regions and inland northwest of Gyeongbuk.

Although the ‘secondary rainy season’ is short, it is characterized by strong and heavy rain.

Especially this year, it overlaps with the holiday season, and heavy rains are expected to come early and cause great damage.

So far, it has been delivered by the Disaster Media Center.
