Here are directions from The Weather Channel on what to do in case of a tornado...
In a Frame Home
Make sure you have a portable radio,
preferably a NOAA weather radio, for information.
Seek shelter in the lowest
level of your home (basement or storm cellar). If there is no basement, go to an
inner hallway, a smaller inner room, or a closet. Keep away from all windows.
You can cushion yourself with a mattress, but do not use one to cover
yourself. Do cover your head and eyes with a blanket or jacket to protect
against flying debris and broken glass. Don't waste time moving mattresses
around.
Keep your pet on a leash or in a carrier.
Multiple tornadoes can
emerge from the same storm, so do not go out until the storm has passed.
Do not leave a building to attempt to "escape" a tornado.
In a Mobile Home
Leave your mobile home immediately and take shelter elsewhere.
Outside
Try to get inside and seek a small protected space with no windows.
Avoid large-span roof areas such as school gymnasiums, arenas, or shopping
malls.
If you cannot get inside, crouch for protection beside a strong
structure, or lie flat in a ditch or low-lying area and cover your head and neck
with your arms or a piece of clothing.
In a Car Ideally, you should avoid
driving when tornadoes or other kinds of dangerous weather threaten, because a
vehicle is a very unsafe place to be. If, however, this is not possible, stay as
calm as possible, and assess the situation.
Your best option might be to get
out of the car and lie flat in a ditch or other low-lying area that is
sufficiently deep enough to protect against the wind.
If you do so, beware
of water runoff from heavy rain that could pose a hazard; get as far away from
the vehicle as possible and shield your head from flying debris.
Or, if possible, take shelter immediately in a nearby building
I have lots to do around here to prepare including making a bad weather kit and buying a weather radio. Any ideas about what must be in the kit?
