On my way to work it was raining pretty hard and I didn't see the flood and drove right into it. I got to work and even was able to get home with no problem. A couple of hours later I had gone to my car to go somewhere, and it wouldn't start. It had no lights, no power, no nothing. When I looked under the hood didn't notice anything wrong except my fan was on.

It sounds like there is a problem with the vehicle electrical control module or the battery has gone out, I would remove the battery and have it tested at the auto parts store first. Here is the location of the VESCM so you can see if the electrical connector got wet. Also try to leave the hood open in a dry area to help remove the moisture from the engine compartment.
