If your house has a gas stove, you should be OK as far as cooking goes. Hurricanes don't usually affect local gas lines, since they're underground. All-electric households are obviously the ones that have the most problems here. Even so, many all-electric households still have at least a charcoal barbecue grill, possibly even a gas one. Use that barbecue for boiling water and cooking.
Water can be a problem in areas where there has been extensive flooding.
Sewer lines can back up into the fresh water supply, or water from the lake will contaminate the drinking water. Tainted water is the quickest spreader of disease, so it's very important to listen to news reports in case your water supply has problems. When in doubt, boil drinking water before using. This is why you filled up all of those old milk containers and your bathtubs before the storm hit. These should give you a decent supply of drinking water until you're advised that tap water is once again safe.
