If the storm was bad enough, or if it was an all-day rainy, crappy kind of irop day, then it is possible the bags were offloaded in the rain, also. I don't know if the OP connected, or if it was a direct check-in, but if he or she did connect, it's very possible the drivers were bogged down and late to pick up the bags from the arriving flight. The ramp will try to put bags under the wing, to protect them at least a bit, but most times there are puddles on the ground that everything just sits in. And what makes it even worse is that because it is an irop and most stuff is running late, the crews HAVE to offload the bags as fast as they can, so they can turn the flight back out ASAP. It'd be nice if they could keep the bags in the bins til the drivers showed up to help offload, but most times they "dump" the flight and start loading for the outbound. It sucks, but it's still what is done.
