Stationary Front and Low Pressure System: Heavy Moisture Influx Overnight

[Anchor]

As you have just seen, heavy rain, so intense that visibility is severely limited, is being recorded in various parts of the country, including Seoul. Some areas have already recorded around 100mm of rainfall overnight, which was caused by a large amount of moisture brought in by strong winds.

Overnight, heavy rain of around 50mm per hour poured down across the country.

According to the Automatic Weather System (AWS) managed by the Korea Meteorological Administration, 72mm of rain per hour was recorded in Gimcheon, North Gyeongsang Province, while Gumi recorded 65.2mm, Gyeongsan 50mm, and Boryeong 45.2mm.

In Daegu, where emergency text alerts for disaster-level rainfall were issued, local government monitoring equipment recorded 89mm per hour last night (July 17).

As of 5:00 a.m., over 100mm of heavy rain has fallen in less than 12 hours since last night, mainly in the Seoul metropolitan area, including 123.5mm in Gimpo, 117.5mm in Gangseo-gu, Seoul, and 100mm in Dongducheon.

The stationary front was activated as high-temperature, humid air from the south collided strongly with dry air from the north. In particular, a low-pressure system developed along the front, bringing even more rain.

Overnight, the influence of the low-pressure system, combined with strong winds, brought in a large amount of moisture, causing the rain clouds to grow even more explosively.

The Korea Meteorological Administration forecasted that very heavy rain of 50 to 80mm per hour could fall in southern Gyeonggi Province, southern Gangwon Province, and northern Chungcheong Province until this morning.

The stationary front is expected to gradually move southward from this afternoon, and from tonight, it will bring monsoon rain again, mainly to the southern regions.

[Lee Gwang-yeon / Korea Meteorological Administration Forecast Analyst: The area of concentrated precipitation is also expected to gradually move southward. For the southern regions, heavy rain is expected from the night of July 18 to the morning of July 19.]

The Korea Meteorological Administration urged citizens to be extra cautious about safety accidents such as soil erosion and landslides, as a large amount of rain has already fallen.
