Emergency Management uses a variety of tools to warn you of severe weather or other hazardous conditions. The tools we employ will depend largely upon the type of hazard. But of all of our emergency warning tools, none is more misunderstood than our warning sirens.
When you hear the sirens, DO NOT call 9-1-1 for more information. Go inside and turn on your local radio station, local TV, or listen to your NOAA radio for further instructions.
When the sirens are activated, additional information will be provided as soon as possible on our local TV, radio or NOAA radio system. By calling 9-1-1, you may tie up the phone system, preventing someone with a true emergency from getting the potentially life-saving services they need.
If you are inside and hear the sirens, stay inside! The purpose of the emergency sirens is to notify those of us who are outside to seek shelter inside immediately. San Angelo has 27 warning sirens placed throughout the city. To assure our warning sirens are working correctly , we test them regularly. Every Monday at noon, a "growl" test - a very short activation of the sirens - is conducted. The first day of every month at noon, a complete test of the sirens is conducted. If severe weather is expected during these times, the sirens will be tested the next clear day.
In cooperation with the National Weather Service, Emergency Management uses the Emergency Alert System (EAS) to notify you of a number of hazards beyond severe weather. The best way to receive these alerts is to purchase a NOAA all-hazards radio and keep it in your home. Businesses should get one, too. These radios will sound an alarm and automatically present the warning information for our area.
In addition, to the EAS, Emergency Management works with the City's Public Information Office and the local media to get other announcements to the public, including the weather crawls often seen at the bottom of TV screens.
