If a shelter is not available, get in a bathtub with a mattress over you. Kneel on the floor, put your head on the ground facing an interior wall, and fold your arms over the back of your head. Even when they are tied down, mobile homes are not safe. If no shelter is available, get out and lie on the ground. Don't lie in a drainage ditch or stream bed.
Flash floods happen often with tornadoes.
Don't make the mistake of thinking only those in the midwest need to worry about tornados. While you may not be ready to remodel your home for a saferoom, be aware of the safety risks tornados bring and be prepared to handle them. Thinking ahead will be valuable to you and your family later. Pick a place in your home where you will go during a tornado warning. Sound a tornado warning, and practice going to your meeting spot with your family.
