A tornado watch does not mean tornadoes are imminent - just that conditions might favor their development. Watches mean just that- 'watch' and be alert. Weather Warnings are issued by the local offices of the National Weather Service. Warnings are only issued when severe weather is imminent. A Tornado Warning means that a tornado has been spotted, or that Doppler radar indicates a thunderstorm circulation which can spawn a tornado .
Any tornado sighting causes a tornado warning to be issued.
If the weather looks bad, turn on a radio or television. Local media is well aware of the priority placed upon accurate weather information by persons in Central Indiana. Most local TV channel have a crawler or a graphic on the screen which indicates a weather concern. Radio stations frequently repeat weather information, particularly a watch and most definitely a warning. Remember that in many instances a tornado warning is not issued until the tornado is already on the ground- not a good time to consider what is a safe place.
