Be sure that you let the wood dry completely--to match the moisture content of the rest of the floor--before you make a decision about doing anything. The one thing that you might want to consider before the middle of the summer is to step lightly on a board at a time and see if you can press some of the cup out. Don't press so hard that you split the boards. If you can move them to flat, drive a couple of nails into a joist and at angles to hold the wood toward the flat side. This is tough to explain without a visual, but you want the nails to be at a Vee shape pushing down the edges or the center, depending which way the cup is pushing. Set the nails and put the wax type filler in the nail holes.
If you have any problem doing this, just stop and let the wood dry.
