Emergency Warning Systems

Emergency Warning Systems are real-time watch and warning messages that require your immediate attention due to an advanced or immediate concern for public safety. It is recommended you not rely on just one form of warning, but rather two or more.

Alert Denton

Alert Denton is a new system from Everbridge that has replaced the CodeRED platform for alerts during emergencies and other critical events.

All residents, including those who currently receive text or email notifications through CodeRED, are encouraged to register to receive emergency communications through Alert Denton. Alert Denton Frequently Asked Questions.

To receive Alert Denton messages through SMS, download the Everbridge app on the Apple App Store or the Google Play Store.

Outdoor Sirens

This warning system is not designed to be heard indoors. Denton operates 22 outdoor warning sirens that sound during severe weather events and serve to alert people who are outdoors to take shelter. The sirens are designed to sound for a maximum of 15 minutes when the National Weather Service has issued a tornado warning, or in the event of wind speeds in excess of 70 miles per hour or hail at least 2 inches in diameter.

NOAA Weather Radio

The NOAA Weather Warning Radio will activate and sound an alert for severe weather watches and warnings. They can be purchased at most electronic stores, and many models can be programmed to receive weather alerts specifically for Denton County. This warning system is recommended for individuals who don't live near an outdoor warning siren.

Wireless Emergency Alerts (WEA)

WEA are emergency messages sent to your cell phone by authorized federal, state, local, tribal and territorial public safety and weather officials to alert you and help keep you safe during an emergency. Learn about the FEMA Mobile App.
