As the east coast prepares for Hurricane Irene, it is important to remember that the Centers for Disease Control (CDC) has a Hurricane Helpful Hints website.  The current topic is “What You Need to Know When the Power Goes Out Unexpectedly.”  This topic covers food safety, safe drinking water, extreme heat or cold, first aid for electrical shock, powerline hazards and cars, avoid carbon monoxide, safety at work during power recovery, be prepared for an emergency, and the impact of power outage on vaccine storage. 
If your looking for a list of emergency supplies you should have on hand, the CDC and Red Cross put together a list at the CDC website for Emergency Preparedness and Response – Get a Kit.  From that website is the following list of items you should assemble:

• Water—one gallon per person, per day (3­day supply for evacuation, 2­week supply for home)
• Food—non­perishable, easy­to­prepare items (3­day supply for evacuation, 2­week supply for home)
• Flashlight
• Battery­powered or hand­crank radio (NOAA Weather Radio, if possible)
• Extra batteries
• First aid kit
• Medications (7­day supply) and medical items
• Multi­purpose tool
• Sanitation and personal hygiene items
• Copies of personal documents (medication list and pertinent medical information, proof of address, deed/lease to home, passports, birth certificates, insurance policies)
• Cell phone with chargers
• Family and emergency contact information
• Extra cash
• Emergency blanket
• Map(s) of the area

Hope this helps everyone prepare.  Remember be safe, careful, and cautious.
