A TORNADO is a violently rotating column of air that extends from the base of a thunderstorm. A condensation funnel does not need to reach the ground for a tornado to be present. A debris cloud beneath a thunderstorm is all that is needed to confirm the presence of a tornado.
A TORNADO WATCH is issued by the National Weather Service when conditions are favorable for the development of tornadoes in and close to the watch area. Watches are usually issued for four to eight hours. During the tornado watch, people should review tornado safety rules and be prepared to move to a place of safety if threatening weather approaches. Listen to a NOAA Weather Radio or local TV or radio newscasts for up-to-date weather information.
A TORNADO WARNING is issued by the local National Weather Service when a tornado has been detected by Doppler radar or sighted by storm spotters. A tornado watch does not have to be in effect for a tornado to form. If a tornado warning is issued for your area, seek safe shelter immediately. Tornado warnings are usually issued for 30 minutes. Continue to listen to your NOAA Weather Radio or local TV or radio newscasts for up-to-date weather information.
