I grew up in New Orleans and went through Hurricane Betsy in 1965, among other hurricanes. Two weeks of no electricity, three weeks of no school and no telephone, but at least our house was still there, minimally damaged.
For hurricane preparations, besides evacuation plans, you also need a battery operated radio, fresh batteries, bottled water, nonperishable food, a manual can opener, some way to heat the food (charcoal grill outside, natural gas stove inside), candles and matches. It also helps if your house is built so that opening the windows allows breezes. Plywood to cover your windows with, or else crisscross them with duct tape (plywood is better but you have to be able to nail or screw it into the window frame). Some modern houses are built with hurrican shutters -- great invention! Also make sure the gas tank in your car is full! Now I know I've left something out....
