911 for Kids
A Weather Siren System is a system used to warn the general population
of a tornado warning. Whenever severe weather threatens
of Marengo County the E-911 Center is ready. We have the sole
responsibility of turning the weather sirens on in the
event of a tornado
Q: Why can’t I hear the siren in my house?
A: Sirens are designed to be outdoor warning systems. Many
individuals can hear sirens in their homes, but that is not
intended purpose. Sirens are only one part of the warning systems
used to alert citizens. Weather radios, which are better suited
indoor warning, are also part of the warning systems used to alert
citizens. Most newer weather radios have the capability to
citizens inside their homes about dangerous situations through an
Q. Are all of the sirens activated at the same time?
A. The siren system has been created in such a way that not all sirens
have to be activated at the same time. The idea is that only
in the area affected will be sounded. The area where the sirens will
be activated is generally determined by the area
covered by the
warnings issued by the National Weather Service.
If only the City of Demopolis is under a Tornado Warning then the Sweet Water Siren will not be set off.
Q. Is there an “All Clear” signal?
A. There is no all clear sounding for the siren system. If the sirens
sound for a second time, it does not mean it is safe to come out
Please be aware that the weather sirens will NOT sound for the duration of the tornado warning. Just because the weather siren
stops sounding does NOT mean that the chance for a tornado is over. All citizens should listen to the radio or television for
confirmation that the tornado warning has been canceled.
Q. What Should I Do if I Hear the Sirens?
A. If the sirens are activated - and it is not a monthly siren test -
the public should:
* see it as a signal to seek shelter inside
* tune in to radio or television to get information,
instructions and recommendations
* listen to your local media for indications that the
emergency is over.
Q. When will the sirens be set off?
A. Marengo County E-911 will
set off the weather
sirens in the event of a
Warning- Forecast issued when a particular weather hazard is "imminent" or already occurring (e.g., tornado warning). A
warning is used for conditions posing a threat to life or property.
Marengo County E-911 will
set off the weather sirens in the event of a
Watch- Forecast issued well in advance to alert the public of the possibility of a particular weather-related hazard (e.g. tornado
watch, ). The occurrence, location and timing may still be uncertain.
Q. If I call 911 can they give me more information?
A. NO! Our dispatchers do not receive any reports that are not put out
to all citizens. Theses alerts can be received by a having
weather radio, Weather apps, tv/radio, on Facebook at National
Weather Service Birmingham or Marengo County E-911.
