Common questions
What is the difference between a winter storm watch and a warning?
A watch means conditions are favorable for a significant winter storm, so be prepared. A warning means the hazardous weather is imminent or already happening, so take action.
Is it safe to heat my home with the oven?
No. Ready.gov says never to heat your home with a gas stovetop or oven, because of carbon monoxide poisoning and a higher risk of fires and burns.
How much water does the kit builder plan for?
One gallon per person per day, the figure CDC and Ready.gov use, for drinking and sanitation. Children, nursing mothers and people who are sick may need more, and so may anyone in a hot climate. Pets need water too: ask your vet how much.
How many days should my kit cover?
The American Red Cross suggests a 3-day supply for evacuation and a 2-week supply for home. Ready.gov's list says several days. Pick 3 days for a go-bag and 2 weeks for supplies at home.
How much food is that?
Ready.gov asks for at least a several-day supply of non-perishable food. FDA uses 2,000 calories a day as a general guide, so the builder shows that total for the adults in your home. Children's needs vary with age.
Do I have to buy everything on the list?
No. Most homes already have much of it. Tick off what you have and the list shows only what is left. Our picks are there if you want a starting point, and every comparison page says who shouldn't buy.
