That message will be followed with approximately a 30-second steady tone, followed by an approximate 30-second alternate steady tone, followed by an approximate 30-second pulsed steady tone, followed by Westminster Chimes. The test will end with a test message. The test message is "Attention: This is a test of the City of Tyler outdoor early warning system. This is only a test. If this were an actual emergency, you should tune to your local radio station, 600 on your AM dial. This is only a test." In the event the National Weather Service issues any type of watches or warnings for Smith County, the systems will not be tested.
