The Tennessee Valley is no stranger to severe weather, in fact, we have two severe weather seasons. Outdoor warning sirens are one of many ways to be alerted during severe weather and here in North Alabama there are a total of 510 sirens.
While these are useful, they are truly meant to be heard by individuals outdoors. Madison County Emergency Management Director Jeffrey Birdwell reminds residents not to “rely on an outdoor warning siren, it’s called an outdoor warning siren for a reason. They were designed to notify people who are outdoors and not in front of their tv, near a radio.”
According to Birdwell, the 131 sirens in Madison County are activated on a polygon basis. What this means is sirens that are located within the tornado warning polygon will be activated. They are able to determine the specific sirens using their computer software. There are only two other counties that activate sirens based on polygons, DeKalb and Marshall counties.
Second Severe Weather Season Fast- Approaching

The remaining counties across the Tennessee Valley activate every siren if a tornado warning is issued within that county. One of the counties that use this method is Colbert County. “Currently ours is manually set off here at the office and we go by the entire county so if any one particular part of the county is under a tornado warning we activate all sirens in the county,” says EMA Director Michael Smith.
Franklin County EMA Announces Mass Alert System
Like all other technology, sometimes these sirens may go down due to maintenance or because they need to be replaced. This is the reason why it is so important to have multiple ways to receive weather alerts.
The Live Alert 19 app is a great way to get weather alerts right away. Other ways to stay up to date when severe weather strikes are purchasing a NOAA radio or signing up for your local EMA’s alert system.
