Car cover? I think the wind will blow that off quick and the cable may do more harm than good beating up against the bottom & sides.Parking garage and maybe throw a tight cover on it to offer some protection from flying debris that finds it's way through the sides. Those things are all concrete. It's not going anywhere. Then just hope for the best. This is why we have auto insurance.
What reasons would trump getting out of the direct path of one of the worst predicted hurricanes in recorded history?Can't leave because of several reasons.
^^THIS!If you can't leave and don't have a garage I would try to rent a storage unit that has them for vehicles. It will at least protect it from flying debris. If you are getting one probably better get it soon before they are all rented.
