Mesquite Siren Systems
The City of Mesquite has an extensive system comprised of 25 Outdoor Warning Sirens strategically located throughout the city. These are activated from the Police Department. 

View the locations of the Outdoor Warning Sirens. 

Mesquite's Outdoor Warning system is meant to warn residents who are outside only. Because of the way homes and vehicles are built today, it is difficult to hear them inside. We encourage residents to purchase a NOAA weather radio in order to hear alerts indoors. 

The type of siren that the City maintains will rotate 360 degrees sounding a steady tone for 3 minutes. Depending on the type of situation, it may be continually activated until the danger passes. There is no all-clear message. 

Monthly Siren Audible TESTING
The City of Mesquite tests the Outdoor Warning System the first Wednesday of every month at 12:00 p.m., weather permitting. 

When Sirens Will Sound 
 The City of Mesquite Office of Emergency Management will activate the Outdoor Warning System when: 

• The National Weather Service (NWS) issues a Severe Thunderstorm Warning with destructive winds in excess of 70 mph or a Tornado Warning, for areas within or around the City of Mesquite.
• Trained storm spotters have reported a tornado in the City of Mesquite, or in neighboring jurisdictions, that could potentially affect the City of Mesquite. Reported hail of 1.25 inch in diameter or greater.
