This typhoon Maysak has brought extremely severe losses to Guangxi. Hengzhou was cut off from water and power, seawater backed up into Fangchenggang, Guigang suffered severe waterlogging, and the Liulan Reservoir burst its banks... Although its wind strength was only at the tropical storm–severe tropical storm level (8–10), which is not classified as a strong typhoon, the flooding disasters it caused were more severe than those caused by many typhoons rated 12–14, with enormous losses. In meteorology, this is referred to as a “weak-level, strong-disaster” phenomenon. For this Maysak typhoon, the wind strength was not the strongest in history (Typhoon Rammasun in 2014 was a level-17 super typhoon), but the unusually wide flood coverage in small and medium rivers, and the large number of rivers simultaneously exceeding warning levels, are rare in the past two decades; large areas of urban waterlogging and many reservoirs at risk meant that the scale of the flood-and-drowning disasters ranks among the top five since the founding of the People’s Republic of China.
