About Hyper-Reach

Hyper-Reach sends thousands of messages to geographically targeted households in seconds, and can simultaneously deliver them to an even broader audience via social media, as well as sending broadcast messages to most current mobile telephones in an affected area using FEMA’s Wireless Emergency Alert (WEA) system.


Subscribers will get important, geographically-targeted messages from the Allen Police Department and the City of Allen related to:

  • Emergency response information
  • Missing persons
  • Crime alerts
  • Outdoor warning siren tests
  • Road and facility closures
  • Utility service alerts

During the sign-up process, you can also opt-in to weather alerts related to flash flood warnings, severe thunderstorm warnings and tornado warnings from the National Weather Service.
