The Gulf of Mexico Alliance has put together state-specific handbooks to help you get ready for a hurricane and of other natural disasters, including floods and tornadoes. These are free pdf downloads, so, you have no excuse not to take a look at the handbook for your state and see if your disaster plan is missing anything.
The book is more than just a checklist. They include radio stations you can turn to for information in your area, websites that can provide additional information on things like flood risk, and agencies and organization that may be able to provide you with guidance or assistance before, during, or aftter a disaster. Because these are in-depth guides, the files are pretty big. It may take a few minutes for it to download .
Please note, these links are not direct to the pdf, in case the link
changes. They are links to a page that has information about and a link
to the handbooks. You may have to scroll down a bit to find it. These pages also have a lot of other information that you may find useful.
If you live in an Atlantic Coast state, I'd suggest downloading one of
these handbooks anyway, because while they may have some state-specific
info that won't apply to you, they'll have a lot that will be the same
for any coastal community.
