现在正是暴雨当值的季节，当我们一看到这个词“狂风暴雨”的时候，很自然就会想到它的英语表达“Rain cats and dogs.”

由于英语受北欧文化的影响，在古代北欧神话中，狗象征风，猫象征雨。所以“猫和狗”象征“狂风暴雨”。

例句：

We do not want it to rain cats and dogs.

我们不想让它变成倾盆大雨。

狂风暴雨就是雨下得好大哇，那你也说的狂风暴雨有好多表达的，所以最好paraphrase成你易于理解的差不多就行了吧，反正我感觉下雨总是有风的，风多大，雨就多大，你同意吗？所以地道点的说法有三

① It's pouring/bucketing it down.

Pour：意思就是rain heavily without stopping瓢泼大雨

例句：

It's pouring now.

现在下着瓢泼大雨。

It poured all night.

倾盆大雨下了一整夜。

It was pouring down with rain at three o'clock.

3 点钟的时候下着滂沱大雨。

Pour down/Bucket down：同样地rain very hard雨倾盆而下

例句：

It's been bucketing down all day.

倾盆大雨已下了一整天。

Suddenly rain started to pour down.

突然间大雨倾盆而下。

② Downpour ['daʊnpɔr]

n. 倾盆大雨；注下

是一场突如其来的躲避不及的瓢泼大雨。

比如说：

当我们正在举行野餐的时候，忽然大雨倾盆，是不是很大煞风景？

可以这么讲：

We were having a picnic, when suddenly there came a downpour, which was rather a fly in the ointment.

=Torrential rain 倾盆大雨、暴雨，就是very heavy rain。

例句：

Torrential rain, squalls and wind were expected and the weather forecast warned that downpours would bring more flooding and landslides.

暴雨和狂风预期还会来。气象预报警告，大雨将会带来更多的大水泛滥及山泥倾泻。

③ It's pissing it down.

Piss down

[俚语]下大雨：rain heavily

例句：

Christ, it is pissing down there!

天哪!外面正下着大雨呢!

直译的就是我直接查字典找到的单词，有以下：

Storm / tempest / cloudburst / rainstorms 暴风雨

注意：不要说a strong storm 或 a hard storm，而要说a big storm, a bad storm, 或 a violent storm.

例句：

That night, a storm blew up. 那一夜,风雨大作。

This river used to get flooded whenever there was a rainstorm.

过去一下暴雨， 这条河就发大水。

The north wind came, and driving rain.

北风刮来，接着又下起了倾盆大雨。

The bus was delayed by a cloudburst.

由于大暴雨,公共汽车来迟了。

The sailors took in sail when the tempest was approaching.

暴风雨来临之际,水手们将帐篷放下。

我认为以上这些词你随便替换都无伤大雅，反正大家都懂你就是想说暴风雨，雨好大，风也好大！

其他关于大雨的表达词加点形容词就好了，

a fierce storm 强风暴　

the fury of a storm 狂风暴雨 　　

the bluster of the wind and rain 狂风暴雨

the violent thunderstorms 强烈的雷暴 　　

the violent storm 暴风 　　

一场大雨：

a flood torrent of rain

a heavy downpour

a pounding continuous torrent rain
