- Outdoor Warning Sirens
Southlake operates six outdoor warning sirens that sound during severe weather events. The sirens are placed throughout the city and are designed to warn people who are in common outdoor areas such as parks and shopping centers. The sirens are not meant to be heard indoors. The outdoor warning system will ONLY be used when there is severe life-threatening weather and not for regular thunderstorms and small hail.
The City of Southlake highly recommends each home and business have other means to receive severe weather warnings and alerts, including internet, radio, TV or a NOAA weather radio which can be programmed with a code to activate when there are storm warnings in our region.
The City of Southlake only activates the sirens in the following conditions:
In 2016, the City of Southlake introduced two new mobile warning outdoor sirens. The sirens are the first of their kind in North Central Texas and are utilized during community events. These mobile sirens can act as loudspeakers and are capable of providing event-specific warnings and information to large gatherings of people.
The City of Southlake tests its Outdoor Warning System on the first Wednesday of each month at 1:00 pm, if weather conditions allow. If conditions are favorable for severe weather on a test day, the test will not be conducted.
