Susan, that's an outstanding article. As a Hurricane Hugo survivor, I can add one suggestion.
After Hugo, phone circuits were jammed for days. Yes, that was before all of us had cell phones. However, down here in coastal Georgia, cell phone service gets spotty if the electricity goes out after a thunderstorm.
Our evacuation plans include a phone contact outside of the storm area. With family all over the country, they have one person to call for information on us. This really helps free up call loads within the area hit by the storm. It's a great way to quickly let everyone know where you'll be during the storm, and what you may need afterwards.
We've also purchased a small battery pack/charger. This handy item can jump a car battery, or power a cell phone charger.
