The country normally experiences heavy monsoon rains and its mountainous topography increases its vulnerability to landslides; however, the reported casualties this season are higher than usual.

[5] According to the Korea Meteorological Administration, the annual monsoon season began on 25 June 2023 and ended on 26 July 2023, with an average precipitation of 648.7 millimetres (25.54 in).

[1] Flooding expert Cheong Tae Sung of South Korea's National Disaster Management Research Institute said that the fact that the rains occurred in the rural parts of the country, which are harder to monitor and reach, could be a reason for the higher death toll.

He additionally stated that climate change was a possible cause, as rain in South Korea has been coming in more intense bursts rather than spread out over a longer period of time due to warming, making it harder to prepare for floods.

[9] On 17 July, Yonhap News Agency reported that 628 public facilities and 317 private properties were damaged by the heavy rain.

[7][12] On 15 July, a landslide occurred in the village of Baekseok-ri, Hyoja-myeon, Yecheon County, North Gyeongsang, which killed five seniors.

[15] A flood warning had been issued four hours before the accident, leading some to criticize the local authorities and the provincial government for not closing the tunnel.

[22] Yoon designated thirteen areas "special disaster zones", which would make them eligible for financial support in relief efforts.

[28] The death and subsequent attempts at investigations provoked significant controversy in South Korea and damaged the public appoval of the presidency of Yoon Suk Yeol.

[33] In September 2024, the Legislation and Judiciary Committee of the South Korean Parliament passed a bill calling for a special counsel probe into allegations of government interference into the investigations on Chae's death.
