A heavy rainstorm hit Mianning, Sichuan at night. How much rain fell?

According to the weather forecast issued by the Liangshan Meteorological Bureau in recent days, it is expected that there will be heavy rain in various places. There may be moderate rain in Suining and Xide, and there will be heavy rain in some areas. There may be flooding; at present, local strong convective weather is very obvious in this state, so it is necessary to prevent the possible harm caused by local strong convective weather, such as short-term precipitation, hail, short-term strong winds and severe thunderstorms.

The flood originated from a small valley east of Yihai Town, Mianning County, Liangshan Prefecture, Sichuan Province, and flowed from east to west. Heavy rain that night turned Hanoi into a disaster. Continuous floods, a devastating mix of rock, silt and branches, raged downstream, leaving chaos everywhere. Asiguji's home is located at the easternmost end of Wu Village, only a few dozen meters away from the river. Asiguji participates in training organized by the government twice a year. The most important thing is to discover and notify village cadres in time.

The upper reaches of the river are narrow and the water level rises quickly. After Asiguji saw this, he called the supervisor downstream. After the result, Asiguji informed his family and one or two families around him to evacuate immediately.

Before Asiguji called, Ojemuyi had called Asiguji to pay close attention to the rising water level in the ditch.

According to the division of labor, we arrived at our home on the edge of the village around 11 p.m. It's too late to knock on doors. He could only shout: "The water is rising, the water is rising, let's go!" ?

Asimuga’s family has eight members. At someone's prompt notification, the whole family ran out quickly. As they ran and shouted, more villagers ran out and evacuated to safer areas away from the river.

The news came that with the efforts of squad leader Asiguji and other village cadres, most of the villagers were safely transferred.

And unfortunately, a family of five in the village died in the flood, and only three of the other eight survived. How much did it rain that night? According to official information, more than 200 millimeters of rain fell in just 7 hours.
