The Role of Tornado Warning Sirens in Public Safety

Tornado warning sirens play a crucial role in public safety by providing audible alerts to communities about imminent tornado threats.

It's important to note that sirens are designed to be heard outdoors and may not be effective indoors, especially if windows are closed. Therefore, it's essential to have multiple sources of information, such as weather apps or NOAA Weather Radio, to stay informed about severe weather conditions.
