Thank you cjedge08. I had the same issue and was also looking at the door seals, etc. Your reply got me on the right track.
Here is a picture for reference for anyone else with this issue. As you can see in the picture, the hose came loose and was dumping rain water into the foot well. Before I re-attached it, i pushed a long zip tie through to make sure it was not clogged up, and blew the compressor down through the white 90deg elbow.
I also removed the drivers seat, and door trim and B-pillar trim to pull back the carpet and expose the underneath padding. It was soaked, as there was about 1" of standing water in the well, mostly near the pedals as I was parked on my driveway sloped downward. I put a fan blowing on the underneath of the padding to help dry it out.
