Storm Warning Sirens
- What should I do when I hear the sirens?
- When you hear severe storm sirens, go inside and tune to local media to get more information.
- Why can’t I hear the sirens in my house?
- Sirens are an outdoor warning system designed only to alert those who are outside that something dangerous is approaching.
- How can I get alerts when I’m at work or in my house?
- For alerts indoors, every home and business should have a NOAA Weather Radio All-Hazards. NOAA Weather Radio is like a smoke detector for severe weather, and it can wake you up when a warning is issued for your area so you can take appropriate action.
- When are sirens tested?
- Sirens are tested monthly on the 3rd Monday of every month at 10:00 am.
- Will the sirens warn me of every dangerous storm?
-
Herculaneum has an Early Warning Storm System. The system has two recorded voice messages and warnings.
Warning system signals:
Constant wail - Tornado Warning
Hear an example of the Tornado Warning Siren
Intermittent Blasts - Severe Storm Warning
Hear an example of the Severe Storm Warning Siren All storm warnings and tests are accompanied by loudspeaker voice announcements.
- The safest approach is to be proactive and use all of the information available to protect yourself and your family from threatening weather. Nothing can replace common sense. If a storm is approaching, the lightning alone is a threat. Sirens are only one part of a warning system that includes preparation, NOAA Weather Radio, and local media.
- Who activates the sirens?
- Sirens are activated by city officials through the Pevely police department.
