I have lived here in Sowal since 1986 and before that, in Fort Walton since 1971. I have never had any damage to any of mine or my parent's homes. I think there is some danger of a branch or someones lawn chair breaking a window but I've never had that happen. During Opal I had every leaf on every tree blown off my yard in old Seagrove but no damage to my house/windows.
Basically, I believe most damage comes from water in low lying areas and tornadoes within the storms. If it is a Cat 1 through 3 the winds are not bad enough to damage your home unless you have loose shingles, poor construction, live in a trailer or something like that. If it is a Cat 4 or 5 your roof will probably blow off and any amount of plywood on the windows is going to make no difference at all. I think people spend far too much time, money and energy on running around "boarding up the house". I makes everyone feel better but broken windows are rarer than most think. I am not advocating anyone do what I have, this is just my personal experience. At any time during even a Cat 1 storm a tornado can take your roof off boarding up or not.
Now, having said that, the above opinion reflects my feeling about stuff, houses and the things that have to do with stuff. I have another opinion about life and limb altogether. I, personally would NEVER stay in any house during any storm above a Cat 1; I have done it and it is too stressful for me. While I am willing to risk a broken window or two, I believe the chances of tornadoes within hurricanes is far to dangerous to roll the dice on. The past few storms I have stayed in large, multi-story concrete buildings. I don't normally evacuate as long as I can stay in a big concrete building; non of which I have ever seen blow over in a storm unless the Gulf was pounding on it like on Pensacola beach.
A lot of the tornado's happen north of here after the storm meets the resistance of the land. If you do evacuate go in the opposite direction of the predicted track IE: If it is going north toward Atlanta, go to Houston or Orlando/Jacksonville way. We have been lucky no direct hits have come to Sowal as far as I know. Time will tell this year.
