Severe Weather Safety Information

Warning System Signals:

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.

Sirens are an outdoor warning system designed only to alert those who are outside that something dangerous is approaching.

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.

Sirens are tested monthly on the 3rd Monday of every month at 10:00 am.

Herculaneum has an Early Warning Storm System. The system has two recorded voice messages and warnings.

  • Constant wail – Tornado Warning
  • Intermittent Blasts – Severe Storm Warning
  • All storm warnings and tests are accompanied by loudspeaker voice
  • 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.
