Storm and Outage Prep Checklist

The best time to prepare is long before the storm. Work through this list in stages, and tick items off as you go.

Weeks before storm season

• Read your generator manual and run the unit for 15 to 20 minutes under load
• Change oil and check the spark plug and air filter
• Buy fresh fuel, add stabilizer, and store it in approved containers
• Test every CO alarm and replace the batteries
• Buy heavy-duty outdoor extension cords sized for your loads
• Decide where the generator will sit, 20 feet or more from the house, and how you will keep it dry
• List the devices you must power and their watts (see our sizing guide)
• If you want circuits wired to the generator, hire an electrician for a transfer switch or interlock (see our home backup guide)
• Keep a battery-powered or hand-crank radio, flashlights and spare batteries
• Store water, about one gallon per person per day, for at least three days
• Stock non-perishable food and a manual can opener

48 hours before a forecast storm

• Charge power stations to full, along with phones and power banks
• Fill vehicle fuel tanks
• Top off your generator fuel and set out your cords
• Set the fridge and freezer to their coldest settings
• Freeze containers of water to help keep food cold
• Withdraw some cash, since card readers and ATMs may be down
• Refill prescriptions and pack any other needed supplies
• Bring the generator to its outdoor spot and keep fuel stored away from living areas

During the outage

• Start the generator outdoors and confirm that nothing is blocking the exhaust
• Connect appliances one at a time, biggest startup load first
• Keep the fridge and freezer doors shut. An unopened refrigerator keeps food safe for about four hours, and a full freezer for about 48 hours (24 hours if half full)
• Turn off the generator and let it cool before you refuel
• Unplug sensitive electronics until the power is stable
• Keep away from downed power lines and report them
• Check on neighbors, especially older adults

After the power returns

• Turn off the generator before you switch back to utility power
• Throw out refrigerated food that was above 40°F for more than two hours
• Let the generator cool, drain or use leftover fuel as your manual advises, and wipe it down
• Note how many hours it ran and schedule an oil change
• Restock fuel, batteries and water
