Within minutes they can destroy neighborhoods and leave devastation that stretches miles. Tornadoes average a wind speed of 112 mph, but they can produce winds up to 200-300 mph. That's nearly twice the speed of most hurricanes. Straight line winds from thunderstorms often produce tornado-like damage as well. Learn the warning signs.
Tornadoes can develop rapidly and sometimes strike before warnings can be issued.
Postpone outdoor activities if your area is under a watch. A tornado warning means actual tornadoes have been sighted. Choose the right shelter. Even mobile homes with tie downs can be blown away by severe winds. Do not take shelter in a crawl space.
