    Tornadoes appear as rotating, funnel-shaped clouds extending to the ground from thunderstorms. Winds associated with tornadoes can range from about 40 mph to over 250 mph. Damage paths can exceed a mile wide and 50 miles long.

    Tornadoes can occur anywhere at any time - often near the trailing edge of a thunderstorm, often with​​ clear skies behind them.
