Tornado and Lightning Myths

MYTH: I'll see an approaching tornado in time to take cover.
FACT: You won’t always see a tornado. The approach of many tornadoes is masked by heavy rain or hail. In forested, hilly, or built-up areas, tornadoes may not be visible until they are imminent. Some tornadoes do not have a visible column from the cloud to the ground and are noticed only when the debris-laden surface winds are close.

MYTH: I can outrun a tornado in my car.
FACT: The average forward speed of a tornado is 40 to 65 km/h but some travel more quickly than this. Your car may be able to travel faster than a tornado, but you need to follow the road. Tornadoes don't. If you are in a vehicle and a tornado is advancing on you, drive out of its path or seek an alternative sturdy shelter.
