Mass Notification


​​​​​​Being Informed Matters -- Get Notified

The City of Coppell employs a comprehensive emergency warning program and has access to several tools 
that are used to alert the public of emergencies or disasters. It is important to always have multiple ways of 
receiving emergency warnings. A single method alone may not provide be effective at all times or in all situations. 

​​​​​​​Emergency Notification System (NotifyCoppell)​​

  • ​Receive alerts about emergencies and other important community news by signing u​p for NotifyCoppell, an EverBridge system.
  • This system enables us to provide you with critical information quickly in a variety of situations, such as severe weather (with optional opt-in weather notifications), unexpected road closures, missing persons, and evacuations of buildings or neighborhoods.
  • You will receive time-sensitive messages wherever you specify, such as your home, mobile or business phones, email address, text messages, and more. You pick where, you pick how.
  • We recommend you include a cell phone number capable of receiving SMS text messages, as well as email addresses as less invasive ways to receive non-emergency messages.

​​​​​​Wireless Emergency Alerts (WEA) System

  • ​The Wireless Emergency Alert system is a public safety warning system that allows customers who have certain wireless carriers and an enabled mobile device to receive geographically-targeted, text-like messages alerting them of imminent threats to safety in their area.
  • The technology ensures that emergency alerts will not get stuck in highly congested areas, which can happen with standard mobile voice and text data services.
  • The service is free (i.e. you will NOT be charged for any incoming messages), but requires registration:
    • Find more information on WEAs here.
  • The three types of alerts through this system are:
    • Alerts issued by the President of the United States
    • AMBER Alerts (missing persons)
    • Alerts involving imminent threats to safety of life. In our area, the National Weather Service issues Tornado Warnings and Flash Flood Warnings via WEA.

​​​​PARKS DEPARTMENT'S thorguard lightning prediction system​

  • ​The City of Coppell Parks Department utilizes the ThorGuard Lightning Prediction System in the city parks system.
  • ThorGuard Lightning Prediction units continuously monitor the atmosphere's electrostatic energy and evaluates the potential for lightning within a 15-mile radius.
    • When a detector dete​​rmines the atmospheric conditions will support a lightning strike in the area, a 15-second air horn blast will sound and strobe light will turn on.
    • Upon hearing or seeing these signals, individuals who are outdoors should seek ​appropriate shelter in a sturdy, enclosed structure immediately.
    • When the detector senses conditions are safe, the strobe light will turn off and the horn will sound three short 5-second blasts; normal activity may resume.
  • ​The ThorGuard Lightning Prediction units are active from 7:00am to 11:00pm, seven days a week.
  • ​An interactive map of Coppell's ThorGuard unit locations can be found here.
  • It is important to remember that lightning can occur at any time, even if overhead cloud conditions do not seem ominous; though it may appear to be clear and sunny where you are, "bolts from the blue" can occur up to 10 miles away from its parent thunderstorm.
    • If you see lightning or hear thunder, halt activity and seek shelter for at least 30 minutes without observing any additional strikes/thunder.
    • Head to NOAA's lightning safety page for more information.

​​​​​​​Noaa All-hazards weather radio​

  • ​National Oceanic and Atmospheric Administration (NOAA) All-Hazards Radios are used nationwide, and broadcast weather information directly from the National Weather Service (NWS) from a collaborative network of radio stations. During dangerous weather, they are activated automatically by the local NWS Weather Forecast Office (WFO) when the weather threatens their responsible domain.
  • The City of Coppell highly recommends that you purchase an All-Hazards Weather Radio with the S.A.M.E. (Specific Area Message Encoding) and selectable alert features, and program it accordingly to deliver weather warnings when issued for our area. 
    • Examples of consumer models that offer both these features include the Midland WR300 and Midland WR400.
  • Most weather radios operate on both an AC power wall adapter and battery backup, which is important for emergencies experiencing power failure, as traditional communication mechanisms (TV, radio, landline phone) may not function.
  • Our local area county codes are:
    • Denton County: 048121
    • Dallas County: 048113
    • Tarrant County: 048439
    • Collin County: 048085
  • For more information on NOAA All-Hazards Weather Radios, click here.
  • For help programming your weather radio, you may also call the local Weather Forecast Office in Fort Worth at (817) 429-2631, or look for special​ severe weather awareness events in your community.

​​​​​​​Smartphone Applications

  • ​There are many different phone applications that offer "push" notification services during severe weather. Some are free, and some cost money. Depending on your particular preference, these apps can be downloaded to your smart phone or other device as a tool for weather warning information. 
  • Be sure to enable the "push" notification feature, which allows the app to continuously poll for alerts, and set the alerts to an audible tone that will wake you up at night.
  • Here are a few examples of phone apps that offer push notification alerts for dangerous weather:
  • Many other applications are available for download via the Apple App Store or Google Play, and can be found by performing a simple 'Weather Radio' subject search.
  • Remember: downloading a smartphone application is not a substitute to having a working weather radio.


​​When it comes to receiving important emergency alerts, remember:

"Two is one and one is none!"
