Yes it is correct, but you wouldn't need to say 'after the rain' in actual conversation. You could just say:
So two work colleagues enter office at the same time.
'Did you get caught in the rain too?'
'Yeah it caught me just as I was leaving the house, it hasn't stopped! I'm soaked.'
A little later...
'Have you dried off yet?
'No, not really'
'I've been putting my jacket under the hand-dryer in the bathroom, it seems to have done the job!'
Hope that helps :)
