(Ulsan = Yonhap News) Reporter Jang Ji-hyeon = A sudden torrential rain poured down on Ulsan on the morning of the 29th, causing damage, including soil and sand leaking from the retaining wall of a construction site and flooding of houses.

According to the Korea Meteorological Administration, as of 9:45 a.m. on this day, the accumulated precipitation by observation point in Ulsan area was 34 mm in Ganjeolgot, Ulju-gun, 33.5 mm in Jeongja, Buk-gu, 27.5 mm in Ulgi, Dong-gu, and 11 mm in Jangsaengpo, Nam-gu.

At 8:24 a.m., soil leaked from a retaining wall at a construction site in Hwajeong-dong, and a parked car became trapped in a pile of dirt.

The wheels of the car were submerged in a pile of dirt mixed with mud and rubble, but there were no casualties as there were no people in the car.
