Is accidental flooding covered under comprehensive coverage?

I'm new to area (on a fishing trip). I parked my car where other cars were parked during low tide. The high tide came in and flooded my car.

Sorry to hear about the loss. Yes, comprehensive coverage should cover any kind of flooding that occurs to the vehicle. I would call your insurance company to review it and open the claim. I hope your vehicle gets fixed soon. Please reach out with any other questions that you might have.
