Zhuhai issued a red rainstorm warning. Will this rainstorm cause waterlogging in the city?

I don't think we can give a very definite answer according to the rainstorm whether there will be urban waterlogging this time. Because whether waterlogging will happen in the city depends on how heavy the rain is at that time and what the drainage system of the city looks like under heavy rain.

First of all, we can analyze how heavy the rain is. In essence, such a heavy rain in Shenzhen is rare, and during this time, Shenzhen has been dry and rainy in previous years, so the weather this year is actually abnormal. In autumn, it rains continuously and heavily in the south, which is a very abnormal weather. In the face of abnormal weather, what we should do most is to establish the drainage system of our own city. As long as the drainage system in our city is good, it is very likely that we will try our best to avoid urban waterlogging.

But if our drainage system is not built and there is less rain, urban waterlogging may occur. In fact, the essence of solving urban waterlogging is to strengthen the drainage system. As a city in the south of China, Shenzhen should have a very strong drainage system, so in the face of not very heavy rain, the drainage system is completely adequate, so there is no need to worry about urban waterlogging. However, regarding this weather anomaly, our forecast of the rainstorm is not very accurate, so we are likely to face a heavier rainstorm than we expected at this time, and the relevant departments in Shenzhen also issued a report on this rainstorm when this rainstorm came, so that residents can strengthen their prevention.

In essence, if we can make our urban drainage system excellent, then we don't need to worry about whether there will be waterlogging in the city at all. On the contrary, if the urban drainage system construction is not in place, then a better drainage system should be established immediately when the rainstorm comes, so that residents' lives will not be disturbed.
