Magic Water

So we were recently out for our longest trip so far. We took our new 2012 Crossroads Z-1 out for a full week (8 days). During that time we had some normal nasty afternoon Florida storms move through while we were out. When we got back my wife asked if I spilled a bottle of water in the bedroom. Turns out the bottom of a laptop bag I had next to the bed was wet.

I didn't think much of it at the time. We recently had some nasty storms move through so after work one day I stopped by our storage facility and checked and there was a small puddle of water right where that bag was. Here is a pic...



I checked around the window. Nothing wet. I looked at the roof. Nothing. I felt around the wall. Nothing. I could find no evidence of water other than the puddle on the floor. Obviously this puddle is quite small - but the wetness of the laptop bag was quite a bit more serious.

Any ideas where this is coming from? Should I worry about it?

Thanks.
