rain is going to gradually stop

[E2e4]

It is all about raining which is going to gradually stop.
Are there any other ways to say the sentences below but not using the phrasal verb "ease off".

Rain's begun to ease off.
Seems as if the rain is easing off.
Seems as if the rain is going to ease off.

weaken, decline,fade, ..?

Thanks

First of all, your sentences all lack something, either an article or a subject:

The rain's begun to ease off.
It seems as if the rain is easing off.
It seems as if the rain is going to ease off.

'Easing off' is the most appropriate form and I cannot think of an example which works as well as that. You could say
The rain's not so heavy
which sounds more natural than
the rain's getting lighter.

Would it then be appropriate to say

1) Huh, what a pouring, but it seems as though the rain's getting lighter now.

2) Huh, what a pouring, but it seems as though getting lighter now.

Are there any other words which can be used in such case? (after pouring)

Thanks again

[Beeesneees]

'what a pouring' is not appropriate.

You could use 'what a pour-down'
Huh, what a pour-down, but it seems as though the rain's getting lighter now.
Huh, what a pour-down, but it seems as though it's getting lighter now.
Huh, what a pour-down, but it/the rain seems to be getting lighter now.

If a down-pour with lighting is about to subside, can I say that "it seems the cats and dogs is (are) dying down now".

Thanks

Can't I invent a new idiom? You for sure have got what I meant.
"The cats and dogs are dying down." Let's go!

"The cats and dogs are dying down." is now a new idiom. He he, just wait the confirmation by people all over the world in a decade or two. Thanks

P.S. don't be angry with me for I am an innovative person.

[Beeesneees]

Well done on the innovation.
I predict it won't catch on.

I wonder if you can apply 'petering out' to rain (like conversation) figuratively.

[Beeesneees]

If you mean something like:
The rasin petered out gradually.
The rain seems to be petering out now.
Then yes, those work.

Good thinking.
