[ARCHIVED] Preparedness Pointers

Did you know?

Severe Weather is full of surprises, but how our village tornado sirens should not be one of them. Here are some interesting facts about our outdoor warning system. 

Did you know...

  • Outdoor Warning Sirens are not meant to be the main source of weather warning indoors.
  • Hanover Park currently has six Outdoor Warning Sirens, including one that is shared with Streamwood.
  • Our Outdoor Warning Sirens are tested on the 1st Tuesday of every month at 10am for one minute.
  • Hanover Park will often hear our neighboring sirens being tested. Due to advancements in siren technology, newer sirens tend to have a wider range of warning.
  • When the sirens stop, that does not mean the threat is over. Monitor social media or local news for the All-Clear notification.
  • The sirens will sound for 3 minutes during a Tornado Warning and re-activated after 10 minutes if the threat is still present.  
  • The National Weather Service does not have the capability to take over the radio airwaves in the Chicagoland area. Your cellphone may be your only way of receiving Tornado notification.
  • The National Weather Service uses criteria to activate these sirens. Which means when you hear a siren, a room full of meteorologists agree that the storm has advanced to a serious level of concern within a few miles of our location.
