There has been a noticeable increase in tornadoes in America, especially in the South. There is nothing you can do to prepare your home for an F5 tornado, which produces winds up to 318 mph. Fortunately, F5 tornadoes are rare. Atlas Survival Shelters lists what you can do to prepare your home for a tornado.
You need to find a safe space in your home to shelter from a tornado.
This could be the basement. Ideally, this place is small and windowless, since even F1 tornados can easily smash windows. You could also install residential tornado shelters underneath your home. Underground bunkers usually have toilets.
Basements or bunkers need to be stocked with supplies, in case you and your family need to stay there for a couple of days. Have enough bottled water for three days for every member of the family, including your pets. Have a first aid kit and medication ready. Store blankets, bandages, and beds for the pets. Stock it with non-perishable food that does not need to be heated, like peanut butter and canned fruit. Do not use any food stored in glass because it could break if the tornado is strong enough to rattle your shelter.
Tornadoes are unpredictable, but you can prepare in case of the worst. Along with the shelter, you need to know where public shelters are in your community in case your home is too damaged to live in.
