【知识点】
从气象上来说，24小时降水量（24-hour precipitation）为50毫米或以上的雨称为“暴雨”（rainstorm/ downpour/ torrential rain）。特大暴雨是一种灾害性天气（disastrous weather），往往造成“洪涝灾害”（flood），在山区还会引发“山体滑坡”（landslide）和“泥石流”（debris flow）。Landslide（山体滑坡）是暴雨使山体不堪重负，由山体薄弱地带断开整体下滑，而debris flow（泥石流）是暴雨使沙土石达到水饱和，在重力的作用下液化的泥沙石向低洼处流动。
Zhengzhou received average precipitation of 457.5 mm within 24 hours to 5 pm Tuesday, the highest daily rainfall since the weather record began. The city also reported record-high hourly precipitation of 201.9 mm between 4 pm and 5 pm on Tuesday, the Henan provincial meteorological center said.

Waterlog在词典中的解释是to cause (a boat, ship, etc.) to become uncontrollable as a result of flooding（船只等被水淹后失控）或者to become saturated with water（被水浸透），在这里的语境下表示很多地方都被水淹了。在暴雨中被淹的车辆我们可以用waterlogged vehicles表示，即“涉水车辆”。
