Since China's weather network entered the main flood season in June, the south has experienced five rounds of heavy rainfall. As of today (24th), the Central Meteorological Observatory has issued rainstorm warnings for 23 consecutive days, which is equivalent to seeing rainstorm warnings almost every day. Heavy rainfall caused floods and other disasters in Guizhou, Guangxi, Hunan, and Jiangxi. It is expected that today, southeast Guizhou, northwest Guangxi, central Hunan, central Jiangxi and other places will have heavy rainstorms.
Statistics show that since the beginning of the main flood season in June, the south has experienced five rounds of heavy rainfall, and most areas in the south have been involved. The five rounds of heavy rainfall occurred on June 2-9, June 11-14, June 15-17, June 18-20, and June 20-present.

According to China’s official WeChat official account for disaster reduction, due to heavy rainfall, floods, hail, and geological disasters caused 200 counties (cities, districts) in 45 cities (autonomous regions) in 8 provinces (autonomous regions), including Jiangxi, Hunan, and Guangxi, as of the 8th. 1.736 million people were affected, 9 people were killed and 5 people were missing.
Since mid-June, with the advent of the rainy season in Jiangnan and Jianghuai, the rain belt has obviously moved northward, and rainfall in Jiangnan, Jianghuai, Huanghuai and other places has increased significantly. Starting from June 20, Guizhou to the middle and lower reaches of the Yangtze River also experienced the strongest rainfall since the flood season this year, and there have been heavy rains and even heavy rains in many places. He Lifu, chief forecaster of the Central Meteorological Observatory, said that this round of heavy rainfall has the characteristics of long duration, high intensity, stable position of heavy rainfall, weakening of rainfall during the day, and strengthening at night. This round of heavy rainfall starts on the night of the 20th and will end on the night of the 25th, lasting a total of about 5 days. During the rain, Guizhou was obviously affected.

Today, heavy rainfall is still fierce, and the Central Meteorological Observatory continues to issue yellow warnings for heavy rain. Moderate to heavy rain is expected in northern and western Jiangnan, southern Guizhou, central and northern Guangxi, eastern and western Yunnan, northeastern Hebei, eastern Jilin, northeastern Heilongjiang, and southeastern Tibet. Among them, southeastern Guizhou, northwest Guangxi, and Hunan There are heavy rains or heavy rains (100-180 mm) in parts of central China, central and northern Jiangxi, and western Zhejiang.
Tomorrow, there will be moderate to heavy rain in eastern North China, most of Jiangnan, most of South China, most of Yunnan, southern Gansu, southern Qinghai, and southern Tibet. Among them, southern Anhui, northeast Jiangxi, west Zhejiang, south Hunan, northwest Guangxi, There are heavy rains in parts of northern Guangdong, western Yunnan, and southeastern Tibet, and local heavy rains (100-130 mm).
In addition, there will be more thunderstorms or showers in northern China, northeast China, and central northwest China, and it will be accompanied by strong convective weather such as short-term heavy precipitation and thunderstorms.
According to Hu Xiao, chief meteorological analyst of China Weather Network, since June, the Meiyu District in the south has started the process of entering the plum. This rainy situation will continue until around mid-July.
According to the mid-to-long-term forecast issued by the Central Meteorological Observatory at 10:00 on the 23rd, it is expected that there will be continuous heavy rainfall in the middle and lower reaches of the Yangtze River in the next ten days. Accumulated rainfall in eastern Southwest, Jianghan, southern Huanghuai, southern Jianghuai, northern and western Jiangnan, and northwestern South China The amount ranges from 50 to 120 mm, of which some areas in Jianghuai, northern and western Jiangnan, central Guizhou, and northwest Guangxi have 150 to 200 mm, and the local area can exceed 300 mm; the cumulative rainfall in most of these areas is more than the same period of the previous year4 ~70%, more than double in some areas. In addition, the cumulative rainfall in eastern Northwest China, northern North China, and Northeast China ranges from 10 to 30 millimeters, and in some areas it ranges from 40 to 60 millimeters.
Among them, from the 26th to the 30th, there will be heavy rainfall from the north to the south in the eastern part of the northwest region, the southern part of North China, the Huanghuai, Jianghuai, Jianghan, Yangtze River, and the eastern part of the southwest. Some of the above regions have heavy rains and local heavy rains.
Meteorological experts reminded that the concentrated areas of heavy rainfall have been highly coincident in recent days, especially for the Dabie Mountains in Anhui, western Hunan, central Guizhou and northeastern Guangxi, due to the large amount of precipitation in the early period, the soil water content has been close to saturation and continuous heavy rainfall, The weather risks of mountain floods and geological disasters are relatively high in the above areas, and special precautions need to be taken. In addition, beware of the impact of heavy rainfall on small and medium-sized rivers and urban and rural floods.
