When will the rainstorm in the middle and lower reaches of the Yangtze River end? What is the signal of termination?

The feature of this heavy rainfall is that it will last longer and its intensity will be greater than the same period. The location of heavy rainfall will be relatively stable, the daytime rainfall will be weak, and the nighttime rainfall intensity will be strengthened. This round of heavy rainfall is expected to start at 10 night and end at 15 night, lasting about 5 days.

Heavy rainfall will continue in the future, and rain belts will gather in the middle and lower reaches of the Yangtze River.

This rainfall is mainly concentrated in Guizhou and the middle and lower reaches of the Yangtze River. It is also the strongest rainfall process since the flood season, and there may be persistent heavy rainfall in the future. Therefore, it is necessary to prepare for mountain torrents from southern Guizhou to Lu 'an, Anhui.

The main area of rainfall will be concentrated in the middle and lower reaches of the Yangtze River, and the accumulated rainfall in the center may reach 200 mm to 300 mm, and even exceed 400 mm in some areas. Judging from the overall rainfall, heavy rainfall will continue to develop in the next three days, and participants will gradually press south, with heavy rains in central and northern Hubei, southern Anhui, southern Jiangsu and northwestern Guangxi.

Cold and warm air flow confrontation brings heavy rainfall and prevents the risk of geological disasters.

On the one hand, the weak cold air from the plateau and mid-latitude areas has been continuously supplemented in the rear, and on the other hand, the warm and humid airflow on the north side of the subtropical high is relatively strong, and the cold and warm air has accumulated in the middle and lower reaches of the Yangtze River for a long time, resulting in heavy rainfall in the above areas, and the intensity is relatively strong. Although the rain belt has moved slightly in recent days, the heavy rainfall in some areas is still very coincident.

Especially in Dabie Mountain area of Anhui Province and central Guizhou Province, there was heavy rainfall in the early stage. At present, the soil moisture content is close to saturation, and continuous heavy rainfall will bring certain geological disasters and meteorological risks to the local area. Therefore, the above-mentioned areas need to strengthen prevention, and this heavy rainfall superposition may cause various problems such as floods in small and medium-sized rivers and waterlogging in rural areas. Relevant departments must strengthen monitoring and evacuate people when necessary.

Extreme weather is frequent, so citizens should travel less.

Since the middle and lower reaches of the Yangtze River entered the precipitation concentration period, the accumulated rainfall of continuous heavy rainfall for several days is more than that of the same period in history. At present, the heavy rainfall caused by the confrontation between hot and cold air will not end in the short term. There seems to be no signal that can be used as a sign of the end of heavy rainfall. This rain belt has drifted to other places, so it doesn't rain.

In fact, it is the rainy season, and rainfall itself is very common. It just means that extreme weather is more frequent this year, so the number of heavy rainfall this year will be much more than last year and the historical data of the same period. If it is not necessary, residents had better not go out, because this rainy season will also usher in a typhoon season, which will also bring a relatively strong rainfall process. Generally speaking, this year is mainly a rain dam. If it is not necessary, try to reduce the proximity to areas where flash floods may occur.
