I agree. See if one of your neighbor's might let you ride out the storm with them. Maybe they have an interior room. You guys don't have basements in FL, right? If you did, that would be the place to go, obviously...Also, make sure your dog is securely tied up in the room with you. If a window breaks, he might spook and run, only to hurt himself on something.
You definitely don't want to be in a basement (not that we have them here) during a big storm surge. The storm surge, not the wind, seems to be Charley's biggest danger right now.
No basements in Florida. No rain run off. The basements would be the first to fill with water. I wouldn't recommend it.
