I seal the windows with plywood cut to size. Storm clips hold these securely in brick, nail to wood. Louvered shutters with working hardware are the best and I am planning to install them on my second floor hard to reach windows.

Double thickness glass provides additional protection for my four smaller windows. Two broke during Katrina.

My double front door faces north and would be blown open by winds over 120 mph. Dropping a bar across the door reduces this chance.

I use one of the sections of my driveway gate as a protective cover for my patio door. It is a glass in wood Anderson door.

It takes me about 6 hours of heavy labor to prepare to evacuate.

Other evacuation checklist items to keep in mind.
0) get things inside....plants present an interesting problem as a long evacuation will kill them no matter where you leave them. I did have a potted ficus that survived a month in the garage after Katrina.
1) Pets are the most common reason people refuse to leave other than just plain stubborness. Having a pet taxi for use in the car is a blessing.
2) Valuable papers and photos (these are the things people have been coming back into their demolished homes to retrieve)
2) Turn off the water and electricity, gas too.
3) Take all the cars (use extra seats to help someone who doesn't have a ride). Even if you dont much like them, you will appreciate having them until you are able to return.
$) You can take valuable stuff like jewelry and silver if you are lucky enough to have any of this...however this stuff is easy enough to replace and you can insure it.
