Dry time for rained on bales

I rolled up 64 4x5 round bales of coastal Saturday. I normally put it in the barn the next day, but we got 5 inches of rain Sunday (today) on the bales. How long do I need to wait before putting in the barn? Tips on what to look for before I store it.

I stack the bales two high barn.
