Hardwood floor got wet - how can I minimize / fix damages?

Unfortunately a wet jacket got the floor very wet (a small puddle started forming).

I didnt notice til 12 hours later.

floor currently looks like this

Any ideas / tips, what I can do to fix the swollen "seams"?
I have been blow-drying it (cold air) for the past 15 minutes.

Anything else I can or should do?

Thanks for your help.
