Public alert and warning tools are essential to save lives and protect property during emergencies and disasters. Before, during and after an emergency, it is important that you know how to receive essential information and announcements from authorities. Consider how you will get alerts and information when you are at home, work, school, travelling or in other locations. This page provides you with some resources on staying informed on potential or developing situations. Please remember to get emergency information from trustworthy and reliable sources!

Communicating Before, During, and After Disasters
iceIt is important to be able to communicate with your friends and family during and after a disaster. You can prepare in advance and be ready to tackle disrupted networks, loss of power and interrupted service. For instance, a short text message is more likely to make it through a crowded network rather than a phone call. The Federal Communications Commission (FCC) and Federal Emergency Management Agency (FEMA) have created a short brochure that might help you prepare your communication plan.


Automatic Alerts:


Emergency Alert System (EAS)

EASThe Emergency Alert System (EAS) is a national public warning system that requires broadcasters, cable television systems, wireless cable systems, satellite digital audio radio service (SDARS) providers, and direct broadcast satellite (DBS) providers to provide the President with communications capability to address the American people during a national emergency. The system also may be used by state and local authorities, in cooperation with the broadcast community, to deliver important emergency information targeted to specific areas. To hear an EAS broadcast, simply tune into a television, radio or cable station. (Source:


Wireless Emergency Alerts (WEA)

wireWireless Emergency Alerts (WEA) are very short (<90 characters) emergency messages sent by authorized government alerting authorities. WEA are sent through your mobile carrier and will look like a text message. The WEA message will show the type and time of the alert, any action you should take, and the agency issuing the alert. They are designed to get your attention in a critical situation, but may not give all the details you receive from other notification services. With WEA, warnings can be sent to your mobile device when you may be in harm's way, without need to download an app or subscribe to a service. You are not charged for WEA messages. WEA may include:

  • Extreme weather, and other threatening emergencies in your area
  • AMBER alerts
  • Presidential alerts during a national emergency



Outdoor Warning Sirens

SirenAlmost all communities have a number of outdoor warning sirens. The sirens are called outdoor warning sirens because their primary purpose is to alert people who are outside to severe weather. The system is not designed to provide notification inside of your home or business.

Contact your municipality to learn more about the siren locations in your area.

In Case of Emergency (ICE)

The acronym ICE stands for In Case of Emergency. This program encourages participants to enter “ICE” into their cellular phone’s contact list and attach the name and number of someone who should be contacted in an emergency. Emergency responders seeing this will know who to call if something has happened to the owner of the phone. ICE was the brainchild of a paramedic who had encountered difficulties getting contact names from shocked or injured patients. 


American Red Cross -- Safe and Well

redAfter a disaster, letting your family and friends know that you are safe and well can bring your loved ones great peace of mind. However, amidst the chaos and communication interruptions, this may not be simple to do. The American Red Cross has designed a website to help make that communication easier. On the Safe and Well website, users can register themselves and loved ones can search through a database of registrants.


American Red Cross --Patient Connection

When local emergencies happen, searching for an injured loved one can be a slow and complicated process. The American Red Cross created the Patient Connection program to help expedite this R2process. The program reunites hospitalized disaster victims with family and friends, offering one central hotline where families can obtain information. This eliminates the need to call or drive around to multiple hospitals to look for a loved one. Patient Connection is activated when a local incident sends 10 or more people to hospitals. A call center is opened so people can inquire about those who may have been hospitalized. Patient Connection is available in Illinois and northwest Indiana.


Emergency Contact Database -- IL Secretary of State

215px-Seal_of_Illinois.svgThe Illinois Secretary of State allows residents with an IL driver’s license, driving permit or ID card to enter emergency contact information into a secure database.
