Outdoor Warning Sirens

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.

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

The siren 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.

The City of Mesquite tests the Outdoor Warning System the first Wednesday of every month at 12 p.m., weather permitting.

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 one inch in diameter or greater.
  • A Chemical Emergency.

Watches vs. Warnings

The most important thing that you and your family can do to prepare for an emergency situation is to know the difference between a watch and a warning.


Conditions are favorable for the development of a hazardous situation.

A watch always means that conditions are favorable. In order to issue a watch, there must be some amount of lead-time which usually involves a type of media coverage about a potential hazard. Some hazards, such as a hazardous material spill, rarely provide any time to allow for a watch to be issued.


A hazardous condition exists. It is time to take immediate actions to protect yourself and your family.

Just like the watch situation, this can be used for any type of hazard that may affect residents in this city. The City of Mesquite may issue warnings as soon as on-scene responders verify assumptions, reports are received from other jurisdicitions, multiple citizen reports confirm supsicions or other similar reports confirm a hazardous situation. Multiple warning devices will be used.

It includes the Outdoor Warning Sirens, Emergency Alert System of North Central Texas, AT&T Cable Override, KEOM Radio and mobile emergency units to allow for multiple alerts.

When a warning is issued in your part of town, make sure that you have your family's Disaster Supply Kit and Emergency Response Plan in tow with you to the shelter, safe room, or to the car if an evacuation has been requested.
