Damaging wind from thunderstorms is much more common than damage from tornadoes. In fact, many confuse damage produced by "straight-line" winds and often erroneously attribute it to tornadoes. Wind speeds can reach up to 100 mph (161 km/h) with a damage path extending from hundreds of miles. To learn more about thunderstorms go to JetStream - an Online School for Weather.
