WOW !

Have you thought about writing a book? Seriously.
I think what they mean is to go at right angles from the direction the tornado is traveling. In other words if the wind in the tornado is 100 mph it may be advancing towards you at only 20 mph, go sideways, not straight away from it.
Easy to say now, not so easy to do.
