Whats that strange noise that I hear on the radio when you issue a tornado warning or do a tornado test?
Those are digital data feeds. The federal government requires us to participate in a national program called the “Emergency Activation System”. EAS was designed to provide a means to notify everyone in America of a national disaster. Perhaps the greatest use of the system, though, is local notifications for local emergencies. When there is a tornado, we activate the EAS system. The EAS data burst that you hear is a digital message to other EAS receivers in the area, and we follow it immediately with spoken information on the emergency.
