It's possible but not definite unless it is a real incline where they are planted. What is most likely is that it floated many of them into clusters and clumps. Once they sprout you can thin them out or transplant them as needed.

Of course you can always over seed the area again to be safe but will likely have to really thin them out then.

I did reseed the area that I planted up the day before the hard rains...it was one solid puddle. But I'm leaving the other beds alone. After those 2 rainy days we had 85 degree weather, and it will be 90 today. If those seeds don't start popping up soon, I guess I'll have my answer!
