If you're at home, go to your basement or an inside room, without windows, on the lowest floor. The safest place in the home is the interior part of a basement. If you don't have a basement, go to an inside room, without windows, on the lowest floor. This could be a center hallway, bathroom, or closet.
If your apartment building has a basement, that is the safest place to be during a tornado. However, if you're on the 2nd floor and cannot access the basement, find the most secure area available. Cover yourself with something sturdy, like a mattress or thick blankets, to protect against flying debris.
Lowest floor, near the center, away from windows, preferably in a hall closet, or bathroom. Basements are the best.
If you cannot go down go in. Go to an interior room. A bathroom or bedroom closet will work in an emergency. A bathtub is good. Avoid windows and glass doors. If possible grab shoes, pillow, blanket.
In a house with no basement, a dorm, or an apartment: Avoid windows. Go to the lowest floor, small center room (like a bathroom or closet), under a stairwell, or in an interior hallway with no windows. Crouch as low as possible to the floor, facing down; and cover your head with your hands.
In an apartment: Get to the lowest level (go to a neighbor's apartment on the first floor, if possible.) Regardless of what floor you're on, get in a bathtub or interior closet. If you are on a higher level and can't get to a lower apartment, hunker down in the breezeway of the apartment building.
An approaching cloud of debris especially at ground level, even if a funnel is not visible; A loud roar - similar to a freight train - or a strange quiet occurring within or shortly after a thunderstorm. A change in the color of the sky. Debris dropping from the sky.
Being underground in a basement is certainly preferable in all situations. You'll need to be underground to survive an EF5 tornado, as that will completely remove a house from its foundation and can even strip concrete and grass from the ground.
"Always have blankets to be prepared, always cover yourself." Peck-Chapman added: "The idea with a ditch, too, is that it's lower than the ground level, so any debris that's flying from the tornado is gonna pass over top of you."
Homes built with insulated concrete forms (ICF), like Fox Blocks, maintain their integrity during the high winds of a tornado. Insulating concrete forms can withstand winds of over 200 mph.
So, while it's not a foolproof plan — remember that bathtubs aren't inherently heavy enough to stand firm no matter what — sheltering yourself in the tub is a good idea if your bathroom is windowless and located in your home's interior.
Closets and interior hallways are often best because of the lack of windows, which can explode or be blown in during tornadoes.
Sleep on the ground floor.
That's safer than sleeping in a second-story bedroom in case a tree falls on your roof. If you live in a one-story home, sleep on the side of the house with the fewest trees or away from the direction of prevailing winds.
Texas leads the nation in the number of tornadoes that occur each year on average, followed by Kansas. Texas leads the nation for the average number each year only because of its size.
As the air descends, it gets warmer and drier. As it covers an area, things tend to get quiet and calm. Many animals sense the change and know a storm is coming. They take shelter, so you won't see or hear them.
A sound a little like a waterfall or rushing air at first, then turning into a roar as it comes closer. If you see a tornado and it is not moving to the right or to the left relative to trees or power poles, it may be moving towards you.
Try to get to some type of structure for shelter. If nothing is available, as a last resort, go to a low-lying area, such as a ditch, and lie flat. Try to protect your head. Hopefully the flying debris (which is the cause of most deaths and injuries) will fly over you.
There are several atmospheric warning signs that precipitate a tornado's arrival: A dark, often greenish, sky. Wall clouds or an approaching cloud of debris. Large hail often in the absence of rain.
