According to the Storm Prediction Center in Norman, OK, if a tornado warning is issued, get into a basement or the lowest level of your home and avoid windows.
If possible, get under some sort of sturdy protection, like a workbench or heavy table, or you can cover yourself with a mattress or sleeping bag.
If you're in a location without a basement, it is advised to get into a small center room, like a bathroom or closet, under a stairwell or in an interior hallway. Crouch as low as possible to the floor, facing down, and cover your head with your hands.
A bathtub may offer some protection as well.
If you're driving when a tornado warning is issued, park the car as quickly and safely as possible, out of traffic lanes.
Get out of the vehicle and seek shelter inside a sturdy building.
If you're not in the vicinity of a building, run to low ground away from any cars and lie as flat as possible, face down.
Avoid seeking shelter under bridges and highway overpasses.
