g37 floors soaked, please help

i have a 2012 g37 coupe and it recently stormed where I live. I noticed that when i got in my car the air was moist and my windows were foggy. I looked in the back to see if someone had left food or smth back there only to find my rear driver seat floor soaked like a literal puddle. every other floor (passenger, rear passenger, and driver) was moist. I tried getting most of the water out with towels and paper towels, but I really don’t know what the problem is. i did some checks and i think water might be leaking from the bottom of the door panels, but idk. Im really just looking for some next steps because i have 1-2 weeks before the next rain and Id really like to fix this if theres a hole or something somewhere before then. if anyone has any idea whats wrong, Please help, and should I take it to the dealership to get looked at? a collision repair shop? my mechanic? thanks. 🙏🏼
