Typhoon Maysak brought intense rainfall to China, causing rivers throughout the region to swell beyond capacity. In Nanning, the surge of water proved too much for existing defences, leading to the collapse of a reservoir wall and releasing a torrent of floodwater into the city below.

The disaster has resulted in at least two confirmed deaths, prompting local authorities to declare the maximum level of emergency alert for flood control operations. The incident demonstrates how tropical storms can rapidly overwhelm engineered flood-mitigation systems when precipitation exceeds design tolerances.
