It is raining more heavily now


The rain is getting heavier

From English Grammar Today (Cambridge University Press):

Adverbs with more and most

Adverbs with two or more syllables form the comparative and superlative with more and most:

We need to treat the environment more carefully.


Heavily is an adverb. It is qualifying the intensity/amount of rainfall.

Heavier is an comparative adjective. It compares a state with another state.

Here, the correct use will be the first one, ie, It is raining heavily. This is a complete sentence itself.

You can use the second one in informal/casual conversation. It is more of a cropped form of : It is now raining heavier than it was earlier.
