You had them outside in that storm?
My above advise was for inside, in that whatever can spill them will spill them.
With only two varieties, you can easily grow them out again next year and likely figure out which is which, unless they are near identical tomatoes.
I once spilled a container with 16 vials of 16 different early determinate small round red varieties. There was no way to grow them out and figure them out. So, I tossed about 16,000 seeds.
Don't worry about sending tomato seeds for this year's swap. There's always been plenty to go around.
