As heavy rain warnings were issued for parts of Daegu and North Gyeongsang, an underpass was submerged, leaving vehicles stranded, and residents were rescued from flooded dwellings, among other rain-related damage.
According to the Korea Meteorological Administration, at 10:10 p.m. on the 17th, a disaster-level heavy rain emergency alert text was sent to Jisan-dong in Suseong District, Daegu, as 31.5 millimeters fell in 15 minutes. Earlier, at 10 p.m. the same day, a standard heavy rain emergency alert text had been sent to the same area.
A disaster-level heavy rain emergency alert text is sent when the one-hour accumulated rainfall is 100 millimeters or more, or when both one-hour rainfall of 85 millimeters or more and 15-minute rainfall of 25 millimeters or more are met. The threshold is higher than for the standard heavy rain emergency alert text, which is sent when one-hour rainfall is 50 millimeters or more and three-hour rainfall is 90 millimeters or more, or when one-hour rainfall is 72 millimeters or more. Since this system was introduced this summer, this is the first time it has actually been sent.
More than 100 reports of flooding were filed with Daegu City, mostly concentrated in Jisan-dong and Beommul-dong in Suseong District. Around 10:20 p.m., Daegu City restricted access in both directions on Sincheon-dongno due to concerns about flooding. Earlier, at 10:05 p.m., a driver was rescued from a vehicle stranded on the flooded Sincheon-dongno, and at 10:12 p.m., another driver was rescued from a vehicle at a hospital near Sincheon-dongno.
Also at 8:13 p.m., strong winds and heavy rain caused a tree to touch a high-voltage line, cutting power to about 400 households in Sincheon-dong and Sinam-dong in Dong District. KEPCO carried out emergency repairs, and power was restored around 10 p.m., about two hours later.
Daegu City is responding under level 2 of the heavy rain warning and addressing the damage. A Daegu City official said, "There are flooded roads in many places due to the heavy rain," but added, "So far, we have received reports of damage such as flooded commercial buildings, but there have been no reports of casualties."
Kimcheon in North Gyeongsang, where a heavy rain warning is in effect, recorded 107.5 millimeters of rainfall on the day. The highest hourly rainfall was around 7:42 p.m., at 72 millimeters. In North Gyeongsang, Gyeongsan saw a daily rainfall of 110.5 millimeters, and Gumi recorded 88.5 millimeters.
Across North Gyeongsang Province, a total of 72 damage reports were filed: one rescue of a person, 42 road obstructions, 13 flooded dwellings, and three rockfalls, among others. In Gumi, a family of four isolated by a flooded dwelling was rescued by a fire rescue squad and evacuated.
Heavy rain advisories are in effect for 11 locations in Daegu and North Gyeongsang, and heavy rain warnings are in effect for central Daegu and for Gumi and Gyeongsan in North Gyeongsang. According to the Daegu office of the Korea Meteorological Administration, between now and the 19th, 50 to 100 millimeters of rain (up to 150 millimeters) is expected. An official at the Daegu office said, "After heavy rain through the 19th, rain is expected to continue for the time being."
