Myth 1:	When a tornado approaches, the sky will have a green hue, or color.
Fact 1:	Only in a few cases will the sky ever turn green. This is caused by a large amount of airborne debris, mainly dust and dirt, which is filtering the sunlight.
Myth 2:	You should open windows in the house to equalize pressure.
Fact 2:	Pressure will naturally equalize through cracks and small openings in your house anyway. You will waste valuable time opening windows in your house that should be spent seeking shelter.
Myth 3:	Tornadoes are graded by visual size.
Fact 3:	A tornado is graded by the damage it causes not on its size or wind speed. The wind speed is based from damage caused by the tornado. Example... A tornado with 300 mph wind speed which lands in an open field and only scatters dirt will be graded lower than the same size tornado that strikes a metropolitan area.
Myth 4:	Areas bordered by lakes, rivers, or bluffs are safe from a tornado.
Fact 4:	No safety is offered by any natural land feature, unless it's underground. Many towns supposedly thought safe in the Platte River Valley of Nebraska have been struck by a tornado. No disrespect intended but, ask the people in Grand Island about that one.
Myth 5:	You should wait until you hear the sirens sound before you take shelter.
Fact 5:	By the time you hear the sirens sound it may be too late to take shelter. Sounding the sirens is up to the perrogative of those in charge of your area's warning system. Self awareness, not sirens, is the best precaution.
