From the night of July 18, an obvious rainfall process will bring heavy rain to parts of 9 provinces and cities such as Hubei and Henan.

According to the Central Meteorological Observatory, in the past week, rainfall was biased towards the north, and rainfall in most parts of northwest China, southern North China, eastern Huanghuai, central Northeast China, western and eastern Inner Mongolia, northern and central Sichuan was significantly higher than normal. It is predicted that the rain will come again from the night of 18, and the local accumulated rainfall is relatively large. The eastern part of southwest China, Huanghuai, northern Jiangsu, Anhui and other places need to be alert to the secondary disasters that may be caused by heavy rainfall. At the same time, the rain will also "quench thirst" for northeastern Sichuan, northern Chongqing, western Hubei, southeastern Shaanxi, southwestern Henan and other places, which is very beneficial to alleviating their high temperature and drought.

Rainfall forecast: It is predicted that from July 18 to July 20, 2022, there will be an obvious rainfall process from west to east in Sichuan Basin, Yunnan, Guizhou, Huanghuai, Jianghuai and other places, and there will be heavy rains in the above areas, including northeastern Sichuan, northern Chongqing, western Guizhou, northwestern Hunan, central Hubei, southern and eastern Henan, southern Shandong, northern Anhui and Jiangsu. Some of the above areas have short-term heavy rainfall, the maximum hourly rainfall intensity is 30 ~ 70 mm, and the local area exceeds 70 mm, accompanied by strong convective weather such as thunderstorms and strong winds. The cumulative rainfall is generally 40 ~150mm, and the maximum rainfall can reach180 ~ 240mm in eastern Henan, southern Shandong, northern Jiangsu and Anhui, northeastern Sichuan and central Hubei.

Main precipitation periods: from the night of Sichuan, Chongqing, Yunnan, Guizhou and Shaanxi 18 to 19, and from Hubei, Henan, Shandong, Anhui and Jiangsu 19 to 20.

Meteorological disaster risk warning: It is predicted that the meteorological risk of mountain torrents will be higher in the night of 18, such as southern Shaanxi, northeastern and southern Sichuan, northern Chongqing, western and northern Hubei, western Guizhou, northern Yunnan and southern Shandong. During the period, the meteorological risk of floods in some sub-basins of Huaihe River Basin is high, and the meteorological risk of floods in small and medium-sized rivers in southern Shandong Province is high.

Meteorologists have warned that the geological conditions in Sichuan, Chongqing, Yunnan, Guizhou, southwestern Shaanxi and western Hubei are fragile. The public should guard against disasters such as flash floods, landslides and mudslides that may be caused by short-term heavy rainfall, stay away from areas with high risk of meteorological disasters, and pay attention to safety. In addition, eastern Henan, southern Shandong and northern Jiangsu and Anhui need to pay attention to the adverse effects of floods in small and medium-sized rivers, urban waterlogging and local heavy rainfall on traffic travel, and the public should pay attention to weather forecast and early warning information in time before going out.
