Well, I said I'd try to update, and I am. We're staying here. Not much choice, really. It would have been entirely too difficult for my wife to handle her Mother, me as a near cripple, and the dogs on a 12 hour trip to the mountains. And, as dmmcarty said, the mountains may not be all that safe, anyway. There are no real good options.
Our house is fairly secure -- as good as any in the area, I'd guess -- and we have 3M film on all the windows that's as good as plywood to prevent shattering (although not breakage). The only thing we really worry about is getting strong enough to take off the roof. We'll be in a central hallway during the actual storm, a narrow passage in the center of the house where there is less chance of something falling down on us.
We're finished bringing in everything from the patio, our cars are filled with gas, we have all the batteries, water, etc. that we need. We brought the motor home over from the commercial property where I normally keep it. It's parked in the driveway across the front of the house, providing a bit of a barrier to both the house and the garage door, and available for us to run the generator and have a bit of power after the storm, if need be. It also has a propane refrigerator and a propane stove that we can use afterwards, along with the grills, which we brought inside to protect. The water tank on the motor home is also filled.
I don't know what else we can do. Thank goodness for friends who came this morning to help gas up and move the motor home, and our son, who took time from his own preparations to help his Mother get everything inside. Our son-in-law and daughter are about 45 miles inland in Okeechobee, and they've boarded up and plan to ride it out. My son-in-law is a fireman there and will no doubt be busy. Our daughter will have the two granddaughters, 2 dogs, cat, and is 6 months pregnant, so that will be interesting...
The latest projection, as of 11 AM, has it going straight over our house...
