When you come across a tornado you need to get in your house and got to your basement. If u dont have a basement get in a bathtub farthest from a window, If u only have a shower and dont have a basement, grab a bed mattress go 2 ur lowest floor and lay under the mattress. I have experienced 2 tornadoes in my life, 1 severe and 1 mild. But trust me, this is what works. =D
