According to the data of meteorological automatic station, from 20: 00 on June 3rd to 20: 00 on June 4th, 20 16, heavy rains occurred in Liuzhou City, Liujiang, Luzhai, Rongshui and Rong 'an, and even in some urban areas.

For Liuzhou, which encounters several rainstorms almost every year, this figure is actually not a "record". The heavy rainfall in the same period of 20 15 was greater than this year, but it is worth mentioning that the rainfall intensity in the urban area 1 hour exceeded 90 mm from 5: 00 am to 6: 00 am on 14. Liu, director of Liuzhou Meteorological Observatory, said that the rainfall intensity in the urban area was rare for many years.
According to the staff of Liuzhou Meteorological Observatory, according to the analysis of relevant meteorological data over the years, Rong 'an and Rongshui are the rainstorm centers within the jurisdiction of Liuzhou, and the probability of heavy rainfall such as heavy rain and heavy rain is high, mainly because of the local topography and climatic conditions. It is easy to form heavy rainfall. Like several heavy rainfall processes experienced by Liuzhou in May, the rainfall and rainfall intensity of Rong 'an and Rongshui are relatively large. From June 13 to June 14, the rainfall system mainly covered Liuzhou City and Liujiang County, and Liuzhou City became a "rain nest".
