Honda Civic Rain Leaks

I have two Honda Civic Lx's. One is a 2010 and the other is a 2011 (No Sun Roofs). We have had alot of rain this week and I discovered both had wet carpets under the all season mats, in the back behind the drivers seat. The top of the mats weren't wet. I noticed water on the driver side rear door limiter. They where parked side by side on the driveway. The windows where tightly closed. The weather strips are tight, clean and free of debris. A wet vac pulled large amounts of water through the carpeting. I didn't find water on any other surface.
The interiors do not smell musty and in the past I haven't noticed condensation which leads me to believe this is the first time for these leaks.
I would value your input.
