well if you are at your house you should go to your basement or your closet
if you are outside try to get under in the safe shelter
if you at a camp then go on the top hills and have a emergency kit
You should not be in a mobile home if there is a tornado coming. Mobile homes are very susceptible to tornado damage and should be abandoned for sturdier shelter during a tornado warning.
Nothing
I'd be looking for safe shelter.
If you can see the tornado
Where you should go in your basement does not depend on where the tornado is coming from, but how the house and basement are arranged. You will want to be away from windows and preferably in a corner. If there is a small room within the basement, the walls can add protection.
If you are in a mobile home and a tornado is coming you should leave and find a sturdier structure nearby, preferably one with a basement or cellar. Some trailer parks in tornado-prone areas have communal underground storm shelters that you can go to.
yes!
If the tornado is close and approaching you, leave the vehicle for some sort of shelter, preferably underground. If you cannot get inside, lie in a ditch or depression in the ground.
You shouldn't. Contrary to popular belief opening windows during a tornado does nothing to save a house and may in fact make damage worse. If a tornado is coming opening windows is a waste of precious time that you should use to take cover.
The best thing that people can do is to pay attention to weather advisories so they can no when a tornado is coming. When a tornado threatens, people should get to some underground shelter or get to the interior part of a sturdy house or building.
If no shelter is available a ditch is your best option as a last resort.
Generally you should shelter in place during a tornado as you are more likely to survive if caught in your house than if caught in a car. Evacuating from a tornado is not as simple as it sounds, as the paths of tornadoes can be unpredictable and it is possible to get stuck in traffic since peak tornado activity often coincides with the evening rush hour. That said, if you are in a mobile home when a tornado is coming you should leave it for sturdier shelter.
