Why is my car making a loud static noise after driving through a big puddle?

What is your question?

I went through a big puddle on my way into work this morning. I didn't see it so I didn't slow down at all. The car is still driving normally, but whenever it's moving, there's this loud noise throughout the whole car that sounds like static. It stops when my car is completely stopped. It did that for my whole 45 minute drive in. What could be making this noise? And if the noise has stopped by the time I drive home from work tonight do I still need to be worried about it?
