Fill the gas tank in your car, charge your cell phones and stock up on cash. If you don't smoke, buy some matches or a Bic lighter. Empty your outdoor trash cans and leave the lids off to catch rainwater. If you've got a small boat outside, fill it with water. If you can't fit it in the garage, toss your lawn furniture into the pool.
Don't make the same mistake I did once... I had plenty of canned food, but didn't have a manual can opener!

If you're prepared, hurricanes can be fun (Cat 3 or less anyway).
