Thank you for attending this public hearing on our new Severe Weather Warning System. I’m Helen Dunley. First, I’d like to remind everyone that the main purpose of a weather warning system is to tell people outdoors to move inside. Now, it's important to remember that we will test the system every Saturday at noon, so don't worry about the noise at that time. It's a good idea to go outside and listen when we test the system and make sure you can hear them in your neighborhood. Remember that the loud noise is only one part of the warning system. The loud noises are activated by city officials after we receive warnings from the national weather service. In other words, you might hear a warning on the national news before you hear a warning here. If you do hear one, what should you do? First, take cover. Our city doesn't have public shelters, so go to the inside of any building, away from windows. Second, wait for reports on local media. Finally, stay indoors until you hear the all-clear signal.
