Heavy rainfall occurred in many places in Sichuan, and13,700 people moved to avoid danger in advance. How long will the heavy rainfall last?

The rainstorm in Sichuan has caused more than 3,500 people in Chengdu, Deyang and Mianyang to be affected, and13,700 people moved to avoid danger in advance. The Sichuan Meteorological Observatory issued a blue rainstorm warning. After the early warning was issued, Sichuan Province responded quickly and made careful arrangements. Sichuan Provincial Prevention and Control Office issued risk warnings to cities (states) and member units of the provincial prevention and control office overnight, organized six cities (states) in rainy areas and provincial national comprehensive fire rescue teams to hold special dispatching meetings, and continued to conduct rolling dispatching and spot checks on 12 county prevention office, six towns (streets) and three key enterprises. Continue to pay close attention to rain and water conditions, strengthen consultation, judgment and early warning of all kinds of disastrous weather, promptly and decisively transfer the affected people and carry out rescue and disaster relief.

The rainfall process in Sichuan Basin will last about a week, the subtropical high is stable, and the water vapor on the west side of the subtropical high is continuously transported to Sichuan Basin. As a result, the rainfall intensity is high, the central areas of heavy rainfall overlap, and the accumulated rainfall is large. The soil moisture content in central and northern Sichuan is close to saturation, the hidden danger points of geological disasters are dense, and the geological environment is fragile, which is prone to landslides and mudslides. Recently, it seems that there are only two kinds of weather, either sun exposure or heavy rain, which makes the weather so violent.

The risk of geological disasters of mountain torrents in the western Sichuan Plateau and the western Sichuan Basin will still be high, so it is necessary to do a good job in disaster prevention. Subtropical high prevails in downflow, and Sichuan basin is affected by subtropical high, superimposed by topographic factors. The air convection in the basin is weak, which makes the heat accumulate, and the southerly wind causes the humidity to increase, which makes the heat unbearable. Rainfall is still mainly concentrated in the north. There will be scattered heavy rainfall in the west of Sichuan basin, the eastern part of northwest China, Huanghuai and Northeast China, and there will be heavy rain in the northwest of Sichuan basin. ?
