If you are in a manufactured home, you should abandon the home in favor of a pre-determined sturdier shelter. This may be a frame home or underground shelter owned by a neighbor, or a community storm shelter. Even weak tornadoes can flip or otherwise cause significant damage to manufactured homes, especially if they are not securely tied down.
If you are caught outside, you should seek out a sturdy shelter, such as a home or office building. If shelter is not immediately available, make an attempt to drive to one. If you encounter flying debris while driving, pull over and park your vehicle. If at all possible, do not park under trees or power lines. At this point you should a.) with seat belt fastened, duck your head below the level of the windows, covering your head with your hands and a blanket OR b.) if it is obvious that you can get below the level of the road, abandon the vehicle and lie down in the lowest spot, making sure to cover your head.
Once you are in your shelter, find a stationary object, such as a workbench, or a sturdy piece of furniture to shelter under. If you are in a bathroom, take shelter in the tub. Cover yourself with heavy blankets, a mattress, or something similar to protect you body from flying debris. Assume the tornado protection position, taking special care to protect your head.
